What Are the Benefits of Autocalibration?

Autocalibration

To achieve the best possible results, 3D printers must be calibrated before printing. That includes the correct positioning of the print bed and the extruder(s) to eliminate dimensional deviations of the 3D print as much as possible. At the same time, correctly adjusting the distance between the nozzle and the print bed ensures good adhesion resulting in better overall quality, less warpage, and fewer failed prints.

The complexity of calibration depends on the type of printer, machine equipment, and application used. It requires knowledge and experience with the machine and is time-consuming and costly. Calibration can also become a significant time factor in the case of frequent material changes or a switch between an operation with and without dual extrusion. To address this, the new BigRep PRO offers autocalibration, taking this task off your hands and saving you time and money.

Autocalibration on the PRO - How Does It Work?

The first step to ensure a properly calibrated BigRep PRO is bed leveling. This can be done by running the 'bed level' function, which initiates the ball sensor to scan a number of points on the print bed. The PRO's user interface will report which areas are not level within an acceptable tolerance and then you simply adjust the bed screws. Bed leveling does not need to be done frequently, but only after initial installation or semi-annual check ups.

The BigRep PRO performs several calibration tasks before each print. The first is bed mapping, which is also used during the bed leveling process. In this case, a sensor ensures that the distance between the print nozzle(s) and the bed is the same over the entire surface of the print bed.

If inconsistencies are measured, the PRO can automatically adjust the thickness of the print layers to compensate for differences. This is particularly crucial for the first print layer, which is essential for successful adhesion between an object and the print bed. This can save you a lot of time on the BigRep PRO. Without precise calibration, the first layer is typically over-extruded to ensure that the print sticks on the printer bed, but this results in sub-optimal quality, as seen in the image below.

Autocalibration
The print on the left is over-extruded. The print on the right has appropriate extrusion, a result of printer autocalibration.

Secondly, the PRO calibrates the distance between the two extruders. This alignment is paramount when bringing out the full benefit of dual extrusion. Only when the control software knows the exact distance between extruders can perfectly aligned structures be printed. Doing this step manually can take a lot more time. Automatic calibration also enables a superior level of precision to manual calibration.

How Does Bed Mapping Work?

The flatness of a print bed, which usually consists of a solid aluminum plate, is an approximation as the surface may slightly deform when heated. This is the case with everything on the FFF printer. However, the larger the print bed, the greater the deviation from the ideal flat surface. Since 3D printers from BigRep - such as the BigRep PRO - are among the largest machines available on the market, a perfect calibration is crucial.

With the aid of the sensor, a network of measuring points is recorded over the entire surface of the print bed. The relative height of each measuring point above an ideal theoretical surface is automatically stored in the software. This enables the printer to adjust the size of the print head—the result is a perfect first layer with a constant material thickness and ideal material adhesion.

The principle used for distance measurement has a direct influence on calibration precision. BigRep decided to use mechanical-inductive surface scanning for the BigRep PRO. Compared to purely inductive or optical methods, it is independent of surface conditions or appearance and allows the detection of printed structures.

A sensor scans the print bed to measure any minor inconsistencies, which are instantly analyzed to adjust the print layers to compensate for bed irregularities.
A sensor scans the print bed to measure any minor inconsistencies, which are instantly analyzed to adjust the print layers to compensate for bed irregularities.

How Does Extruder Calibration Work?

There are some scenarios when dual extrusion is beneficial - or even necessary.

  1. When printing several identical parts at the same time. Both extruders move in parallel, cutting production time per part in half and increasing productivity.
  2. When printing a part using a support material. Since different extruders process both primary and support materials, they can use other materials. For example, they can combine a stable primary material with a water-soluble support material.
  3. When printing two different primary materials in the same component. This procedure allows chemically identical materials to be combined with other colors to achieve visually desirable effects. Alternatively, materials having different mechanical properties can be combined.

In the first case, the exact alignment of the extruders to each other still plays a minor role, as it only influences the position of two parallel created objects on the print bed. These are usually made with sufficient spacing, while exact compliance does not affect print quality.

In cases 2 and 3, extruder calibration is very important. Since printing occurs in the same component, any offset of the extruders is immediately visible and noticeable on the print surface. Support material misalignment results in inadequate support functioning, causing unclean overhangs and concave horizontal surfaces. If different materials are used to print a single part, incorrect extruder calibration can lead to poor material bonding. There are also adverse effects on appearance and dimensional accuracy. The larger the print, the bigger the deviations, resulting in more sunk costs.

Autocalibration
A sensor measures the printed structures to calibrate the dual extruders before printing.

At the push of a button, the BigRep PRO measures printed test lines and uses them to calculate the relative positions of the extruders. In this way, measurement errors are avoided.

Extruders 1 and 2 create two patterns that are offset from each other. The sensor scans the printed structures and determines their distance. These values are now stored in the machine control system and are used to achieve maximum accuracy during dual extrusion. Once the calibration is complete, your BigRep PRO is ready for precise printing.

What is PA12 CF 3D Printing Filament?

PA12 CF is a high-strength engineering-grade filament with excellent mechanical, thermal, and chemical properties. The material is primarily composed of Nylon 12 (PA12), a polymer with wide industrial applications (in packaging, food manufacturing, electronics, and more), and has 10% chopped carbon fiber reinforcement. These carbon fibers enhance the material’s stiffness, heat resistance, and durability, creating even more applications for the 3D printing filament in industrial sectors.

Like all of BigRep’s filaments, PA12 CF has been optimized for large-format 3D printing. This filament in particular is engineered for the BigRep PRO, but it can also be used with fused filament fabrication (FFF) systems with open materials and 2.85 mm diameter nozzles. The material’s primary properties, which we’ll dive into in more detail, are high strength and heat resistance, durability, stiffness, and excellent surface quality—right off the 3D printer.

Benefits of 3D Printing BigRep PA12 CF

When it comes to 3D printing PA12 CF filament, one of the biggest benefits to users is that the large-format filament is easy to work with and requires minimal post-processing. Right off the 3D printer, the material is characterized by a smooth surface finish, minimizing or even eliminating the need for additional chemical or mechanical post-processing. This has a huge benefit: you can save enormous time and resources by being able to use a printed component straight off the build platform.

In the printing process itself, PA12 CF also has certain advantages. For one, the carbon fibers embedded in the Nylon 12 matrix reduce warping on the print bed, which makes for a more reliable printing process and can even enable more complex part geometries. You can achieve the best print results by using an appropriate print bed surface, such as the BigRep SWITCHPLATE on the BigRep PRO.

In order to unlock the most benefits from BigRep PA12 CF filament and maximize the material’s properties, it’s important to use the right combination of print settings.

Recommended print settings

  • Nozzle temperature: 270 - 300 °C
  • Print Bed Temperature: 40 - 60 °C
  • Chamber Temperature: n/a
  • Print Speed: 30 - 60 mm/s

Mechanical Properties

PA12 CF is currently BigRep’s strongest 3D printing material, with a tensile strength of 71 MPa. For comparison, HI-TEMP CF has a tensile strength of 65 MPa, while ABS has a tensile strength of 30 MPa. This effectively means that parts made from PA12 CF can withstand greater stresses before breaking.

Thermal Properties

If you are looking for a material that must be able to withstand high temperatures and retain its strength in demanding environments, PA12 CF is a good bet. With its exceptional heat deflection temperature (HDT) of up to 130°C, higher than BigRep’s other high-temperature material HI-TEMP CF (115 °C). PA12 CF does require a high nozzle temperature (between 270 and 300 °C), and a moderate print bed heat (40 to 60 °C).

Chemical Properties

PA12 CF not only stands out for its mechanical and thermal properties, the large- format filament also boasts very good chemical resistance. The material can withstand exposure to various types of chemicals, including bases, alcohols, oils, and salts without adverse effect. This helps to increase the material’s durability for functional components.

What to Look Out for When 3D Printing BigRep PA12 CF

As with other carbon fiber reinforced filaments, it’s important to update your 3D printer hardware when working with PA12 CF. The fibers make for an abrasive filament that can quickly wear down printer nozzles made from brass. It’s therefore recommended to use a wear-resistant nozzle, such as a hardened steel nozzle, which can print PA12 CF without succumbing to rapid wear. Compared to BigRep’s other carbon fiber filament HI-TEMP CF, PA12 CF also has more demanding hardware requirements, particularly when it comes to nozzle temperature.

Carbon fiber reinforced filaments such as PA12 CF, while being stiffer than neat filaments, also tend to be more brittle. To account for this, you can orient parts strategically on the build platform to ensure that the part is strongest in the direction of stresses and loads. Finally, if you do plan to post-process PA12 CF parts, the material is compatible with a wide range of processes, including sanding, drilling, and milling, as well as coatings like fillers, paints, and epoxies. When post-processing, be sure to wear suitable protection, like safety glasses, gloves, and a dust mask.

Best Practices for Storing and Handling BigRep PA12 CF

To maximize PA12 CF’s resilient properties and final print quality, users should follow proper storage and handling guidelines for the material. The first thing to know is that PA12 CF is a highly hygroscopic material, meaning it easily absorbs moisture from the air. If the filament is stored in a humid environment, the material quality can degrade, and moisture in the filament can cause printing issues, like stringing.

To avoid any moisture-related problems, BigRep advises storing PA12 CF filament spools in a dry environment, such as the BigRep SHIELD or BigRep Keep Dry Box. This is particularly important once the spools have been opened. You can also dry your PA12 CF filament before printing at 80°C for 6 to 8 hours.

In terms of handling, the material requires very high printing temperatures, so users should take necessary precautions and avoid touching the printer nozzle or melted filament. Additionally, good ventilation in the printing environment is recommended (as with all filaments), and personal protection equipment should be worn when performing any post-processing.

Use Cases: Recommended Applications for BigRep PA12 CF

Within BigRep’s extensive filament portfolio, PA12 CF stands out as the most heat resistant and highest strength. These properties, in addition to its excellent chemical resistance, make the filament a good match for a broad range of industrial applications, including molds that can undergo multiple production rounds, jigs and fixtures, and various end-use components.

Along with BigRep’s other carbon fiber filament, HI-TEMP CF, PA12 CF has been of interest within demanding industries like aerospace and automotive, as well as in manufacturing, where custom tools that must withstand the pace and pressures of industrial processes are needed.

In the automotive sector, PA12 CF is ideal for the production of large-format end-use parts. Using the BigRep PRO platform, automotive manufacturers can benefit from the material’s excellent resolution and surface finish, cutting back significantly on time and money spent on post-processing—especially compared to near-net composite parts. The material’s excellent strength-to-weight ratio is also appealing to automotive adopters, who can increase a vehicle’s fuel efficiency by cutting down on weight without compromising on durability and performance.

Another notable use case for PA12 CF is carbon fiber molding. PA12 CF is engineered to withstand high temperatures and pressures, such as those present in an autoclave environment during the carbon fiber curing process. The filament can, therefore, be used to produce large and complex cure tools, which are then laminated with prepregs and placed in an autoclave to cure. Printing the mold directly can eliminate the need for a master pattern, resulting in a more streamlined carbon fiber production process.

Benefits of 3D Printing BigRep HI-TEMP CF

HI-TEMP CF offers a number of benefits to users. In addition to its heat deflection and robust material properties, which are ideal for tough applications, the filament is easy to print. More specifically, the filament is not prone to warping (though it can still be used with a bed adhesive) and has a high quality matte surface finish. This high quality finish straight off the build platform is characteristic of carbon fiber reinforced filaments, which have less distinguishable layer lines. Of course, BigRep HI-TEMP CF can be post-processed using a variety of methods to achieve a superior finish and tolerances.

HI-TEMP CF has a unique combination of material properties that offer many advantages to users, particularly if they are looking for heat resistance and superior durability. The most benefits and best printing results when using HI-TEMP CF can be unlocked by implementing the right printer settings.

Recommended print settings

  • Nozzle temperature: 210 - 240 °C
  • Print Bed Temperature: 50 - 80 °C
  • Chamber Temperature: n/a
  • Print Speed: >40 mm/s

Mechanical Properties

HI-TEMP CF is perhaps best known for its excellent stiffness and durability. With a tensile strength of 65 MPa, the material can withstand significant stresses and loads without breaking. BigRep HIGH-TEMP, by comparison, has a tensile strength of 61 MPa, while ABS has a tensile strength of 30 MPa. The HI-TEMP CF carbon-fiber composite is also lightweight, with a density of 1.20 g/cm³.

Thermal Properties

As the name suggests, HI-TEMP CF was engineered with thermal resistance as a top priority. The filament has a high heat deflection temperature (HDT) of up to 115 °C, surpassing the heat resistance of ABS, ASA, and HI-TEMP materials. In terms of printing temperatures, the filament requires a nozzle heated to between 210 and 240 °C, and best quality print results are achieved with a heated print bed up to 80 °C.

Chemical Properties

HI-TEMP CF is characterized as a chemically stable product, and is resistant to UV exposure. However, the PLA-based material with carbon fiber reinforcement is susceptible to some chemical degradation: it’s recommended to avoid exposure to strong oxidizing agents and strong acids when post-processing or when in use.

What to Look Out for When 3D Printing BigRep HI-TEMP CF

The primary thing to be aware of when printing BigRep HI-TEMP CF is that the material is more abrasive due to the addition of carbon fiber. This means that the printing process requires a heavy-duty nozzle, preferably made from hardened steel. Upgrading your BigRep 3D printer nozzle to accommodate this engineering-grade filament will help to prevent hotend wear and improve print outcomes.

Although warping is not a significant issue when printing HI-TEMP CF, users can benefit from the use of print bed adhesives to improve first-layer adhesion. There are a few adhesion options that work well with this filament, including Kapton tape and Magigoo glue (or a combination of both). Alternatively, BigRep’s removable and flexible print surface, SWITCHPLATE, works well with HI-TEMP CF and does not require additional adhesives.

Best Practices for Storing and Handling BigRep HI-TEMP CF

To achieve the best print outcomes with HI-TEMP CF, it’s important to follow proper storage and handling guidelines. Like many filaments, HI-TEMP CF is hygroscopic, meaning it absorbs moisture from the environment. Printing “wet” filament can lead to issues like stringing and compromise print quality. Fortunately, this can be avoided by storing HI-TEMP CF spools in a dry environment, such as the BigRep SHIELD.

If your spool of filament has been exposed to humidity, you can also dry HI-TEMP CF before printing for 4-6 hours at 50°C. Other storage best practices include keeping the filament out of direct sunlight and storing it at room temperature. If you follow these recommendations, a spool of HI-TEMP CF will easily last for up to 24 months.

In terms of handling, it’s always a good idea to print in a well-ventilated space. Dust and vapors generated in the printing process can cause irritation, so installing the proper vents or a local exhaust, particularly if multiple printers are in use, is vital. Moreover, because HI-TEMP CF requires high print temperatures, users should be cautious around the hot printhead, print bed, and molten filament.

Use Cases: See How Customers Use BigRep HI-TEMP CF

HI-TEMP CF has proven to be a versatile material with applications in a number of different areas. As we saw, the material has high heat resistance (able to withstand temperatures up to 115 °C) and is resistant to bending and stresses, which makes for a well-rounded filament that can meet the requirements of various engineering-grade applications, from functional prototypes to molds, to robust end-use components.

Airflight, a Danish aerospace company specializing in drones and flying cranes, has adopted BigRep 3D printing and HI-TEMP CF filament to streamline and improve its design and production workflows. In one use case, the company 3D printed a large-scale carbon fiber drone mold from HI-TEMP CF, which enabled it to cut its costs by five times compared to traditional CNC milling. The process consisted of 3D printing the mold, reinforcing it with filler, post-processing and waxing the print, and covering it with carbon fiber prepreg. From there, the mold and carbon fiber prepreg were sealed and cured at 100 °C, resulting in a high-quality finished drone component. In addition to the lower costs, using BigRep 3D printing and HI-TEMP CF is enabling Airflight to accelerate lead times and explore more complex shapes.

Also in the aerospace segment, SFM Technology’s AeroAdditive division developed a helicopter blade restraint cradle—the first of its kind—using BigRep’s technology and HI-TEMP CF filament. The part was designed to keep folded helicopter blades safe and steady while the aircraft is aboard a ship, or exposed to wind while stationary. The printed blades made by the AeroAdditive team were designed for aerospace and defense giant Leonardo, which wanted higher-performing cradles for its aircraft. The final products, printed on the BigRep PRO and measuring 900 x 230 x 160mm, certainly delivered. SFM Technology reported that the printed cradles made from HI-TEMP CF outperformed the original components, and the material also provided the necessary durability and weather resistance for the demanding application.

What is ASA 3D Printing Filament?

ASA (Acrylonitrile Styrene Acrylate) is a thermoplastic filament known for its high strength and weather resistance. The engineering-grade material bears many similarities to ABS, one of the most widely used 3D printing filaments, but has some distinct advantages. Similar to ABS, ASA is characterized by good temperature resistance, high impact resistance, and toughness. Where ASA starts to stand apart from ABS is when we look at weather resistance, and specifically UV resistance.

BigRep ASA filament is engineered to withstand UV exposure and is therefore ideal for outdoor applications, like automotive components, consumer goods, sporting equipment, and more. The robust thermoplastic filament also offers a range of other beneficial properties when 3D printing, including a low rate of shrinkage and good layer adhesion.

BigRep Materials

Why Use BigRep ASA Filament?

BigRep ASA is a good fit for many applications, like functional prototyping, tooling, and end-use parts. Optimized for BigRep’s large-format 3D printing—and specifically the BigRep STUDIO G2 and BigRep PRO 3D printers—the filament is particularly handy for making large parts (up to 1020 x 970 x 985 mm) that are used in outdoor environments or are exposed to sun and heat.

In addition to its UV and weather resistance, ASA filament demonstrates excellent impact strength (30 kJ/m²) and good heat resistance. For instance, BigRep ASA has a Heat Deflection Temperature (HDT) of up to 86 °C, meaning that printed parts will not deform under certain loads below that temperature. Ultimately, if you’re looking for a material with similar properties to ABS but with superior mechanical properties, aesthetics, and UV resistance, ASA is it.

Benefits of 3D Printing BigRep ASA

Among the main benefits of 3D printing BigRep ASA are the material’s high UV stability, impact resistance, and heat resistance. Compared to ABS, ASA filament is also easier to print: it tends to warp less and can be post-processed using mechanical methods like sanding or drilling, as well as chemical smoothing methods, like acetone vapor. When printing ASA, it is possible to achieve high quality surface finishes that will last through various climates and weather conditions.

In order to unlock the most benefits from BigRep ASA filament and maximize the material’s properties, it’s important to use the right combination of print settings.

Recommended print settings

  • Nozzle temperature: 200 - 240 °C
  • Print Bed Temperature: 40 - 80 °C
  • Chamber Temperature: n/a
  • Print Speed: >40 mm/s

Mechanical Properties

Starting with ASA’s mechanical properties, the material is known for its high impact resistance and strength. ASA boasts a higher tensile strength (40 MPa) than standard ABS (30 MPa) as well as a superior tensile modulus (1900 MPa) than ABS (1400 MPa). Put another way, ASA is more ductile than ABS and can withstand greater stresses without breaking.

Put another way, ASA is more ductile than ABS and can withstand greater stresses without breaking.

What to Look Out for When 3D Printing BigRep ASA

As we saw, BigRep ASA has numerous benefits, but the material also comes with a couple of challenges. Fortunately, these can be easily overcome by simply adjusting print settings and implementing some print preparation techniques.

The main issue you may encounter when 3D printing ASA filament is warping. Like ABS, ASA is prone to warping on the print bed. This is the result of the printed part cooling too rapidly or unevenly, which causes the material to shrink and pull up from the print surface. The first line of defense against ASA warping is to use a print bed adhesive, such as BigRep Kapton print bed foil and/or Magigoo glue. You can also minimize warping by slowing down the print speed in the first layers of your build. This will help to ensure strong first layer adhesion as the printer deposits more and more layers.

Best Practices for Storing and Handling BigRep ASA

You can make the most out of BigRep ASA filament by following proper storage and handling guidelines. In terms of storage, ASA is fairly low maintenance and can easily last upwards of a year under the right conditions. In this case, the right conditions consist of a dark, ambient environment that is protected from moisture.

A dry environment is important because ASA is somewhat hygroscopic, meaning it absorbs moisture from the air. In order to preserve the quality of BigRep ASA spools, you should therefore store the material in a dry room or a sealed container with desiccant. (That said, ASA is less hygroscopic than other common filaments like PLA and Nylon, so it may not be as critical to dry it if it is briefly exposed to humidity.) For best results consider storing ASA in the BigRep SHIELD, an industrial dry cabinet designed to protect materials from degradation.

ASA filament does not come with any serious health warnings, but significant exposure to fumes created in the printing process can become hazardous to users. To avoid any potential health risks associated with 3D printing ASA, ensure you are 3D printing in a well-ventilated space. If you are running a 3D print farm or a multi-printer operation, for instance, it’s a good idea to install a local exhaust ventilation system.

Use Cases: See How Customers Use BigRep ASA

BigRep ASA has been enthusiastically adopted by a range of industries, but perhaps none more than automotive. The material’s high strength, as well as its resistance to impact, high temperatures, and weather, have made it a popular option for printing automotive end-use components as well as jigs and fixtures for automotive manufacturing and assembly processes.

Zoeller-Kipper, a specialist in waste disposal technologies, has adopted BigRep 3D printing to produce bespoke modifications for waste disposal vehicles. Thanks to its durability and ability to withstand UV exposure, ASA has been a perfect fit for its needs. In one use case, for example, Zoeller-Kipper 3D printed a large ASA part to be mounted on the rear corner of a garbage truck. The end-use part, which weighed 1,824 grams, was printed on the BigRep PRO and was ready within just two days.

Other uses for ASA in the automotive industry include jigs and fixtures, brackets, mirror housings, and manifolds. Outside automotive, ASA is also a popular material choice for 3D printing electronic enclosures, sporting equipment, parts for the maritime industry, and more.

BVOH

WATER-SOLUBLE SUPPORT

AVAILABLE COLORS

BigRep's BVOH support material is a water-soluble filament that drastically reduces post-processing for 3D-printed parts. Created for use with dual-extruder printers, BigRep BVOH is compatible with a wide range of materials to provide efficient support during the printing process. BVOH is ideal when 3D printing complex geometries where breakaway support be difficult to remove or impossible to access after printing. When the surface appearance of your part is paramount, BigRep BVOH results in better surface quality with less post-processing effort.

BVOH easily dissolves in water, cleanly freeing parts from support structures without manual post-processing. While the dissolving time depends on part geometry and slicing settings, BVOH’s solubility increases with higher water
temperature and delivers faster results.

What is BVOH 3D Printing Filament?

BVOH (Butenediol vinyl alcohol co-polymer) is a water-soluble support material. That means it is designed to print temporary support structures that can be dissolved in tap water — cold or warm.

Many 3D printer users prefer water-soluble supports because removal is faster, easier, and doesn’t leave unsightly marks. Supports printed in an insoluble material typically have to be removed with a knife, which creates a surface blemish.

Overall, BVOH behaves a lot like PVA, another common support material. However, BVOH offers superior adhesion to build materials like ABS and is less likely to cause nozzle clogs. It also dissolves at a faster rate, making the support removal process as short as possible.

BVOH Filament - Support Structure

Why Use BigRep BVOH Filament?

BigRep BVOH filament is compatible with all BigRep large-scale 3D printers (and other open-material FFF printers with dual extruders). By 3D printing support structures in BVOH, the support removal process is drastically shortened.

Although BVOH works best with PLA — it has similar temperature requirements and good natural adhesion to it — it is compatible with all BigRep filaments. By contrast, some water-soluble materials on the market are not compatible with certain build materials such as ABS. Naturally, BigRep BVOH is especially practical for large-format 3D printing, as it is available in very large spools: available sizes include 0.75 kg, 2.5 kg, and 4.5 kg (8 kg upon request).

Users of BigRep’s industrial 3D printers will find it easy to incorporate BVOH into their workflow. This is because BigRep has developed a preconfigured BVOH print profile for its BLADE slicing software.

Benefits of 3D Printing BigRep BVOH

There are several benefits to 3D printing BigRep BVOH over other water-soluble support materials like PVA. These include superior adhesion to build materials — even tricky materials like ABS — and ultra-short dissolving times. The fastest speeds can be achieved with warm water, but cold water also works.

So, what makes BigRep BVOH stand out over other BVOH filaments on the market? In addition to the range of spool sizes, BigRep BVOH has been optimized for improved melt flow to prevent clogging and has a slightly lower print temperature than some comparable products.

Unique advantages of BigRep BVOH:

  • Improved melt flow to prevent clogging
  • Adequate tensile strength (34 MPa) to support large prints
  • Wide material and machine compatibility
  • Available in large spool sizes: 0.75 kg, 2.5 kg, and 4.5 kg (8 kg upon request)

Recommended print settings

  • Nozzle temperature: 190 - 210 °C
  • Print Bed Temperature: >60 °C
  • Chamber Temperature: n/a
  • Print Speed: >30 mm/s

Material Properties

BigRep BVOH filament has a low melting temperature of 175 °C. This makes it easy to print: the required nozzle temperature is 190–210 °C, with a bed temperature of 60 °C. These print settings are similar to those for PLA.

Since the purpose of support material is to hold up heavy structures, it also needs to be strong. BigRep BVOH has a fairly high tensile strength of 34 MPa, which is slightly higher than ABS.

The most important property of BVOH is its solubility in water. Support structures can be washed away in cool or warm water, although warm water helps speed up the process. However, keep in mind that the material’s solubility can make it vulnerable to humidity.

What to Look Out for When 3D Printing BigRep BVOH

Newcomers to dual extrusion additive manufacturing may encounter some challenges when 3D printing BVOH. Although the material prints well at moderate temperatures, it has some quirks that require care and attention.

The most common issue with any water-soluble support material is nozzle clogging. And while BigRep has developed a highly clog-resistant BVOH formulation, users should still take steps to minimize clogging by performing regular nozzle cleaning. One option is to perform a cold pull with a dedicated cleaning filament; another is to use a long needle to manually clear out debris.

Finally, users of standard and professional 3D printers may find that BigRep BVOH adheres better to the build surface with the help of an adhesive coating like Magigoo glue stick.

Best Practices for Storing and Handling BigRep BVOH

Like other soluble support materials, BigRep BVOH is highly hygroscopic. This means it absorbs moisture easily, which can become an issue in humid environments.

Because of its hygroscopic nature, BVOH should always be stored in dry conditions at a temperature of 15–25 °C. With a humidity of just 0.01%, the BigRep SHIELD filament dry cabinet is an ideal form of storage, holding up to 60 kg of filament. For non-industrial users, a sealed container with a desiccant should be the bare minimum.

Drying out BVOH filament before use can also lead to better printing results and prolonged printer life. BigRep recommends drying the filament at 60 °C in a hot air dryer or vacuum oven for four to 16 hours.

filament-dry-cabinet-air-flow

Use Cases: See How Customers Use BigRep BVOH

BigRep BVOH filament can be used for any build that requires support structures. Suitable parts include those with overhanging areas that cannot support themselves.

Water-soluble support material like BVOH is especially useful for parts that have internal or otherwise inaccessible overhangs. This is because cavities in the part can be easily filled with water to remove soluble internal supports. Conversely, it is not always possible to reach into a cavity to remove insoluble supports with a knife.

AVI Boston seamlessly weaves technology into crafting personalized and bespoke automotive parts like dashboards, radar installations, door panels, and beyond.

What puts them ahead of the curve is their expertise in integrating cutting-edge audio and visual systems, elevating both the car’s aesthetics and functionality. Their innovative approach is amplified by their use of 3D printing to manufacture end-use parts with BigRep’s STUDIO 3D printer to bring their concepts to life.

Many of these complex parts would be impossible to produce without BigRep's water-soluble BVOH support filament. Owner of AVI Boston, Safi Barqawi, says “We’ve been designing these parts in-house and building clean structures for such intricate pieces. We would never be able to do that by hand. Getting down to that small of a detail is really hard.”

Benefits of 3D Printing BigRep HI-TEMP

When it comes to 3D printing BigRep HI-TEMP, the material has many benefits. For one, the material overcomes many of the challenges associated with printing other stiff, temperature-resistant materials, such as warping and peeling. In addition to minimal warping, HI-TEMP can be printed in an open, low temperature environment, offering excellent adhesion and dimensional stability without an enclosed build chamber.

A low-maintenance material, BigRep HI-TEMP is also known for its excellent surface finish. The filament’s matte appearance minimizes layer lines and results in a smooth finish that requires minimal—if any—post-processing. This is true for both small and large-scale components. It’s also worth re-emphasizing that HI-TEMP is a biopolymer, meaning it is biodegradable in the right conditions. This is a particular benefit when compared to fossil-fuel-derived filaments like ABS.

Recommended print settings

  • Nozzle temperature: 190 - 230 °C
  • Print Bed Temperature: 50 - 70 °C
  • Chamber Temperature: n/a
  • Print Speed: >40 mm/s

Mechanical Properties

With a tensile strength of 61 MPa, HI-TEMP filament offers excellent stiffness and rigidity, particularly when measured against ABS (30 MPa). And while comparable to PLA on the strength front, HI-TEMP far exceeds the brittle filament in terms of unnotched impact strength (45 kJ/m² vs 7.5 kJ/m²).

Thermal Properties

HI-TEMP is perhaps most notable for its thermal properties. While the material can be processed using standard 3D printing hardware and relatively low temperatures, it can withstand temperatures up to 160 °C. Technically speaking, the material has a Vicat softening temperature of 158 °C and a heat deflection temperature of 58 °C. For applications where even greater heat resistance is required, HI-TEMP CF has an HDT up to 115 °C.

Chemical Properties

The biopolymer HI-TEMP is based on is chemically stable, offering some resistance to UV exposure and weak acids.  The material is, however, primarily recommended for indoor use. HI-TEMP is also non-toxic and is suitable for food contact applications.

What to Look Out for When 3D Printing BigRep HI-TEMP

Overall, BigRep HI-TEMP is a filament that offers many pros and few cons. As we’ve seen, the material is easy to print, while still offering high stiffness and temperature resistance up to 160 °C. On top of that, it has an excellent matte aesthetic quality.

Unlike its fiber-filled counterpart, HI-TEMP CF, HI-TEMP does not require any specialized printing equipment, printing well with standard nozzles at around 195 °C. While the material does offer good adhesion on its own, you can still benefit from the use of a bed adhesive, like Kapton tape or Magigoo glue. BigRep’s flexible SWITCHPLATE can be used to facilitate part removal post-printing.

Best Practices for Storing and Handling BigRep HI-TEMP

When using any filament, it’s important that users adhere to the proper storage and handling requirements. By storing HI-TEMP spools out of the sun in a dry, room temperature environment, users can ensure the material’s quality will be maintained for up to 24 months.

BigRep HI-TEMP is considered hygroscopic, meaning the plastic absorbs moisture from the air around it. This moisture can diminish the integrity of the filament, leading to issues like stringing and blobbing when extruded. You can avoid exposure to humidity and wetness by storing the filament in a dry box or the BigRep SHIELD, which can hold up to 60 kg of filament. In a pinch, you can also dry the filament before using it. BigRep recommends drying HI-TEMP for 4-6 hours at 50 °C.

In terms of handling, users of HI-TEMP should follow standard 3D printing protocols, such as printing in a well-ventilated space, avoiding contact with the melted filament, and wearing proper personal protective equipment (PPE) while post-processing parts.

Use Cases: See How Customers Use BigRep HI-TEMP

Sky’s the limit when it comes to BigRep HI-TEMP applications. After all, who wouldn’t benefit from the material’s easy printability, high accuracy, aesthetic quality, and temperature resistance? Among the most common uses for HI-TEMP filament today are industrial prototypes, jigs and fixtures, and end-use parts like homeware appliance components, electrical enclosures, and aesthetic models.

Optimized for BigRep’s large-format printers, including the BigRep ONE, the material can print large-scale components, like customized production aids. In this context, manufacturers can benefit from being able to design and iterate one-of-a-kind jigs or assembly fixtures in-house, reducing lead times by up to 90% and quickly getting production workflows up and running. By turning to 3D printed tooling and strong, temperature resistant materials like HI-TEMP, manufacturers can also seek to reduce production costs by as much as 94%. HI-TEMP also has another important benefit for tooling applications: because the material is resistant to warping and shrinkage, and has a smooth surface finish, printed parts require minimal post-processing before implementation on the production line.

Walter Automobiltechnik (WAT), a Berlin-based automotive manufacturer specializing in the production of vehicle frames, is dramatically improving workflows in their facilities with custom 3D printed tools. The production tools, created with WAT’s BigRep ONE industrial 3D printer using BigRep HI-TEMP, are implemented into quality assurance workflows, reducing time spent on control lines with simple jigs to help semi-automate quality assurance checks. The control systems have cut workflows in half, freeing employee time and reducing order fulfillment time.

On top of that, the filament is a biopolymer, meaning it is derived from renewable sources, and can biodegrade in the right circumstances.

As we’ll see in more detail, PRO HT is a filament with well-rounded properties, offering strength, a good quality finish, and heat and chemical resistance. Thanks to this combination of characteristics, PRO HT has broad potential for many applications, from prototypes to outdoor components, functional parts, wearables, and more.

BigRep Materials

Why Use BigRep PRO HT Filament?

It’s no surprise that BigRep PRO HT has been adopted for many applications across a range of industries. The robust yet easy-to-print filament has been successfully used as a PLA and ABS alternative in the production of industrial-grade prototypes and end-use parts that require a good finish and weather resistance, such as wearables. Unlike PLA, which has limited viability for outdoor applications, PRO HT has excellent UV and heat resistance. Additionally, PRO HT is FDA compliant for food safety and meets EU Directives on food contact, which opens up possibilities for printing homeware and other products that come in contact with food.

BigRep PRO HT is also optimized for a range of printing scales. The filament performs well on desktop machines as well as large-format systems, like the BigRep ONE and BigRep PRO. The filament is therefore an ideal choice for printing both small and large structures for technical industries, such as automotive.

Benefits of 3D Printing BigRep PRO HT

When 3D printing BigRep PRO HT, users will find they are working with an easy going filament. The biopolymer does not require any special settings or hardware, including an enclosed chamber or high-temp 3D printer, and has a smooth, matte surface finish. PRO HT is also formulated for easy post-processing: breakaway supports come off easily with minimal traces left on the part surface finish. (PRO HT is also compatible with BigRep BVOH water-soluble supports.)

Another key benefit of PRO HT is that the material is more sustainable than ABS and other high-temperature petroleum-based plastics. The material is made from a biopolymer sourced from renewable resources and can be biodegraded under the right conditions.

Recommended print settings

  • Nozzle temperature: 195 - 205 °C
  • Print Bed Temperature: 55 - 60 °C
  • Chamber Temperature: n/a
  • Print Speed: >40 mm/s

Mechanical Properties

While PLA maintains a slightly superior tensile strength than Pro HT (60 MPa vs 45 MPa), Pro HT offers more balanced mechanical properties. In other words, where PLA is very strong but brittle, Pro HT is more flexible and impact resistant, with an elongation at break of 13% and unnotched impact strength of 40 kJ/m².

Thermal Properties

Where Pro HT really stands out from PLA is in its heat resistance. The filament has a comparable heat deflection temperature to PLA—meaning they both start to deform under loads when heated to around 54-60°C. However, where PLA starts to soften when exposed to moderate heat (around 60 °C), Pro HT has a far superior softening temperature of 116 °C.

Chemical Properties

Another key advantage of Pro HT compared to standard PLA is the material’s chemical resistance. Pro HT has been engineered for UV resistance, making it viable for outdoor use without degradation.

What to Look Out for When 3D Printing BigRep PRO HT

BigRep Pro HT is a well-rounded filament with few, if any, pitfalls. In terms of printing, the material does not require any special settings and is resistant to shrinkage and warping, even without an enclosed print chamber. As we covered, post-printing the material is seamless thanks to easy breakaway supports. All in all, the filament overcomes many of the challenges associated with standard PLA, like poor heat resistance and UV resistance, while maintaining easy printability.

Best Practices for Storing and Handling BigRep PRO HT

BigRep Pro HT is a non-toxic material that requires standard filament storage and handling. This includes storing filament spools in a dry environment, away from extreme temperatures and sunlight. The BigRep SHIELD, an industrial storage box for filament spools can keep the material protected from all these elements. Should a spool of Pro HT be exposed to moisture, simply dry out the filament for between 4 to 6 hours at 50 °C.

In terms of handling, normal precautions should be taken when 3D printing Pro HT. Ensure there is proper ventilation in the 3D printing environment, including a local exhaust where multiple printers are in use.

Use Cases: See How Customers Use BigRep PRO HT

The application possibilities for BigRep Pro HT are limitless. Users can readily design and print high-quality prototypes, as well as functional parts for outdoor use, wearable devices, homewares, and more. We want to highlight the following case study, from BigRep client JK Automotive Designs, which exemplifies the material’s potential for large-scale production applications.

Based in Massachusetts, JK Automotive Designs specializes in designing and manufacturing custom interiors for cars, including dashboards, consoles, and door panels integrated with audio and visual systems. Over the years, the BigRep STUDIO G2 has proven to be a huge asset to the company, enabling it to print large-scale panels and frames for these custom designs. Pro HT has also become indispensable to the company’s operations, offering good printability, strength, and temperature resistance.

When the company was designing a full interior for a 33 Ford Roadster, it turned to BigRep 3D printing and Pro HT filament to create a custom door panel. In the design process, the JK Automotive Designs team 3D scanned the original door frame, reverse engineered it, and applied the customizations in CAD software. The large door panel was then 3D printed using Pro HT on the BigRep STUDIO G2. In the end, the printing process took just 56 hours and the printed door panel cost $896. Had they used CNC machining for the large component, it would have taken at least double the time to produce, and cost upwards of $3,000. Post-printing, the part was fitted onto a machined panel and finished before JK Automotive Designs integrated a 3D printed armrest and custom electronics.

What is PETG 3D Printing Filament?

PETG is a thermoplastic based on PET (polyethylene terephthalate), which is among the most widely used plastics in the world. PET is known for its strength, chemical resistance, and easy processing, and can be found practically everywhere: it’s used for beverage bottles, food packaging, industrial films, and more. PETG, for its part, shares many properties with PET, only the addition of glycol enhances the material’s durability and printability.

Recognizable by its transparent sheen, BigRep PETG has been optimized for the company’s machines but is compatible on all open-build FFF systems. The material’s excellent strength, toughness, and temperature resistance—not to mention its excellent printability and adhesion—make it a popular alternative to classic filaments like PLA and ABS, as well as a lower cost alternative to engineering-grade materials.

BigRep’s mechanically and thermally resistant PETG Filament

Why Use BigRep PETG Filament?

BigRep PETG’s material properties are a good match for many applications, particularly prototypes, tooling and visual end-use parts. Though it is not as tough as BigRep’s engineering-grade thermoplastics or carbon fiber reinforced materials, PETG does offer enhanced strength, impact resistance, and thermal resistance compared to PLA—all at a comparable price point. This lowers the adoption barrier for the material compared to industrial materials.

In terms of applications, BigRep PETG is popular for creating large-scale design iterations (for prototypes and end-use parts) across many industries thanks to its good quality finish and transparent aesthetics. The material is also a good fit for functional prototypes or end-use parts that require UV resistance and resistance to oils, alcohols, fuels, and weak acids.

Benefits of 3D Printing BigRep PETG

One of the main benefits of PETG filament is that it is painless to print. Compared to other filaments, like ABS, that have a tendency to warp, PETG is largely resistant to shrinkage and warping, and generally displays excellent bed adhesion. The filament can also handle high printing speeds without significantly compromising quality or resolution, and does not require very high printing temperatures.

In fact, BigRep PETG prints best with a nozzle temperature of about 200 °C (BigRep does emphasize that its filament can achieve a smooth flow at temperatures between 190 and 240 °C). The material does not need a heated print bed, but the best results can be achieved with a heated build surface up to 80°C. Another benefit of 3D printing BigRep PETG is that the filament does not generate any odor while printing, unlike ABS and PLA which are known to emit a strong plastic smell when extruded.

Recommended print settings

  • Nozzle temperature: 200 - 250 °C
  • Print Bed Temperature: >60 °C
  • Chamber Temperature: n/a
  • Print Speed: 30 - 60 mm/s

Mechanical Properties

Among traditional filaments, BigRep PETG demonstrates good strength and impact resistance. The material has a tensile strength of 50 MPa, which is notably lower than PLA (60 MPa), however its elongation at break is substantially higher at 15% (compared to PLA’s 4%). This means that PETG is more flexible than PLA and can better withstand impacts without breaking.

Thermal Properties

Where PETG really starts to stand out, particularly compared to PLA, is when it comes to heat resistance. The thermoplastic has a heat deflection temperature (HDT) of up to 70 °C, making it resistant in temperatures up to 10°C higher than PLA. PETG also has a higher glass transition temperature (85°C vs. 60°C), which means it can withstand more heat exposure without starting to soften and melt. In terms of applications, PETG is therefore better suited to outdoor use.

Chemical Properties

One of PETG’s key selling points is its high resistance to chemicals. Not only is the material able to withstand UV exposure, it also holds up in environments where other chemicals are present, including oils, fuels, alcohols, and even weak acids.

What to Look Out for When 3D Printing BigRep PETG

While PETG’s good adhesion is generally a good thing, it can happen that a print gets stuck to the print bed. This happens most frequently with glass print beds and can be prevented by using a buffer layer between the print bed and the first layers of the part. Kapton tape works well with PETG filament, as well as filament adhesives like Magigoo. Alternatively, the BigRep SWITCHPLATE, a removable and flexible build surface, can facilitate the removal of PETG prints.

When it comes to post-processing, it’s also worth keeping in mind that because PETG is very chemically resistant, it’s not a good candidate for acetone smoothing. Instead, the best quality finishes can be achieved using other post-processing techniques like sanding or epoxy resin coatings. When post-processing PETG prints, it’s always a good idea to wear protective equipment, like gloves, mask, and eyewear.

Best Practices for Storing and Handling BigRep PETG

To get the best results printing PETG filament, it’s not only vital to use the right print settings, it’s also essential to follow proper storage and handling guidelines. Like almost all filaments, spools of PETG should be stored at an ambient temperature and away from moisture and direct sunlight.

PETG is considered “moderately hygroscopic”, which means the plastic absorbs water molecules present in the air. These change the composition of the filament and can lead to inconsistent extrusion and stringing when printed. It’s therefore a good idea to store the filament in a dry box, such as the BigRep SHIELD. It is also possible to dry out the filament before use. BigRep recommends drying PETG at 60 °C for 4 to 6 hours.

Finally, even though PETG filament doesn’t emit a strong odor when 3D printing, you should always print in a well ventilated environment. When operating a multi-printer operation, BigRep recommends installing a local exhaust system.

Use Cases: See Applications Using BigRep PETG

BigRep PETG is a versatile filament and can be used to multiple different ends, such as design prototypes, jigs and assembly aids, outdoor products, and end-use parts that require a high aesthetic quality.

One specific application that stands out for BigRep PETG is the GENESIS Eco Screen, an urban architecture project spearheaded by a design team at BigRep. The structure, which stands at four meters, is a fully 3D printed urban biodiversity habitat that was 3D printed using four BigRep ONE printers and a combination of BigRep PETG and BASF’s recycled Innofil3D rPET filament.

The GENESIS Eco Screen’s impressive design was generated based on solar radiation analysis and integrates optimized plant placement based on the environment as well as built-in watering and drainage systems. The large-scale installation also integrates insect habitats to encourage biodiversity in an urban environment. The Eco Screen is a good demonstration of the complex large-scale structures that can be achieved using PETG as well as the transparent, glossy quality of the printed filament.

What is PLA 3D Printing Filament?

PLA (polylactic acid) is a thermoplastic material that has been one of the most popular filaments since the early days of 3D printing. There are a number of reasons for its ongoing popularity. For one, the material is derived from renewable plant-based resources, giving it an environmental edge compared to petroleum-based thermoplastics like ABS. Second, PLA is an easy-going material that prints well at lower temperatures and high speeds. Third, PLA is available in a range of colors and is typically the cheapest filament to buy.

On top of all that, BigRep PLA offers users an appealing combination of strength and stiffness, while being straightforward to print. It’s also worth noting that BigRep’s filament has been tailored for the company’s large-format 3D printers, so that even at big scales, the filament is resistant against warping and shrinking. Natural-colored PLA is also compliant with FDA and EU requirements for food contact.

Why Use BigRep PLA Filament?

PLA filament is often described as a good option for 3D printing beginners. And while this remains true thanks to the material’s excellent printability, the statement doesn’t really reflect the material’s full potential, particularly when we’re talking about BigRep’s optimized PLA filament.

BigRep PLA is a versatile material that has successfully been used for rapid prototyping, visual models, and end-use parts. The low cost of the material; as well as the generally high quality of prints, have made PLA a go-to for prototyping large components, enabling product designers and engineers to iterate and verify designs quickly and affordably.

In terms of end-use parts, BigRep PLA has been used for a range of creative and innovative design projects, like architectural models, 3D signage, marketing installations, and even furniture. The easy-to-print material is also viable for certain industrial applications, demonstrating good strength and stiffness.

Benefits of 3D Printing BigRep PLA

BigRep PLA comes with many advantages. The filament is among the most low maintenance, offering minimal warping, good bed adhesion, and low moisture absorption. Unlike more heavy-duty filaments, PLA does not require any special hardware to 3D print, working well with standard nozzles and low temperature settings. Moreover, because the material does not easily warp, the filament can be used in an open printing environment, not requiring a cooling system or enclosed build space.

Another of PLA’s big benefits comes from the fact that the thermoplastic has a smaller environmental impact than most other filaments. As we saw, PLA is a bioplastic made from renewable plant-based sources like corn and sugarcane. When disposed of in the right environment, the material is also biodegradable:

Recommended print settings

  • Nozzle temperature: 200 - 2§0 °C
  • Print Bed Temperature: 50 - 70 °C
  • Chamber Temperature: n/a
  • Print Speed: 30-60 mm/s

Mechanical Properties

PLA has an interesting combination of mechanical properties. In terms of strength and stiffness, PLA demonstrates a significantly higher tensile strength (60 MPa) and tensile modulus (3500 MPa) than ABS (30 MPa and 1400 MPa, respectively). However, this strength is mitigated by the material’s brittle nature: BigRep PLA has lower impact strength compared to ABS (2 kJ/m² vs. 35 kJ/m³).

Thermal Properties

With a glass transition temperature of 60°C and a melting temperature around 160°C, PLA is one of the least thermally resistant filaments in BigRep’s portfolio. The material has a maximum heat deflection temperature of 60°C, lower than both ABS (91 °C) and PETG (70°C). The upside to its lower melting point is that it can be processed easily at lower temperatures.

Chemical Properties

PLA is not generally considered to have strong resistance to chemicals. Common chemicals like acetone, which is used to smooth layer lines on ABS 3D prints, can degrade PLA and compromise its strength. PLA is also not resistant to UV rays. That said, PLA does offer good water resistance.

What to Look Out for When 3D Printing BigRep PLA

While BigRep PLA doesn’t have many of the warnings that come with other filaments—like possible issues with bed adhesion and warping—there are certain things to take into consideration when using the filament. For instance, despite PLA’s high tensile strength, the material is brittle, resulting in parts with limited impact strength and durability.

PLA also has a low melting temperature and glass transition temperature compared to many filaments. This, combined with poor UV resistance, limit the filament’s viability for outdoor applications, since PLA will start to degrade and deform when left in the sun. For the same reasons, the material is also unsuited for high-temperature applications.

Best Practices for Storing and Handling BigRep PLA

As we’ve covered, BigRep PLA is a low-maintenance material when it comes to 3D printing, and the same is true for storage and handling. By following the proper storage recommendations, a spool of BigRep PLA can have a shelf life of 24 months.

PLA is slightly hygroscopic, so it should be stored in a dry environment, such as a dry box with desiccant or the BigRep SHIELD. When not in use, the material should be sealed and kept at an ambient temperature. If left in a humid room, PLA filament can be dried before printing at a low temperature (50°C) for between 4 to 6 hours. This will help to reduce the risk of stringing, which is a symptom of wet filament.

When 3D printing PLA, it’s normal to notice a smell from the melting plastic. While non-toxic, PLA should be printed in a ventilated room or facility. As with other filaments, if many 3D printers are in use, a local exhaust system should be installed. PLA is also considered flammable and should be kept away from ignition sources.

Use Cases: See How Customers Use BigRep PLA

Thanks to BigRep PLA’s excellent printability and affordable cost, the material is used for a wide array of applications, from rapid prototypes, to large-scale models for architecture, marketing, and furniture.

In one notable use case, BigRep PLA and the company’s large-scale printer technology were used to bring one of renowned architect Mies van der Rohe’s last designs to life. The project was a collaboration between BigRep and the Mies van der Rohe House in Aachen, Germany to celebrate the 130th anniversary of the architect’s birth.

The model in question was based on Mies van der Rohe’s last architectural design, which was never built. According to the architecture house, BigRep’s 3D printing and PLA material enabled them to realize the scaled-down model much faster and for a smaller cost compared to traditional model-making methods. BigRep PLA is also commonly used by architecture studios to produce realistic miniature models of future builds.

The wide color variety of BigRep PLA has also opened up exciting opportunities for next-gen furniture designers, who are leveraging the material’s strength and stiffness—as well as aesthetic quality—to make innovative pieces that break the design constraints of conventional furniture making processes.
