Smart Manufacturing

Operating the BigRep PRO is simple and intuitive. Begin by installing BLADE slicing software and take a moment to review the material profiles available on the BigRep PRO. Although the PRO is an open system platform capable of running a variety of 3rd party materials, we include custom material profiles with our own proprietary filaments, which were developed and certified specifically for the PRO. This dramatically reduces print setup time and allows engineering to immediately begin print requests. Custom sensors are integrated into the PRO which enables real-time equipment feedback and the remote monitoring system allows you to monitor printer performance at any time. Printing large parts takes hours, sometimes days, so it’s certainly convenient to occasionally check in on your parts while finishing other tasks. This is smart manufacturing.

  • Smart sensors for real-time equipment feedback
  • Remote monitoring that enables lights-out manufacturing

High-Performance Processes and Materials for Improved Functionality

Fixtures on an automotive assembly line must be rugged and durable. Before 3D printing, fixtures were designed and machined using subtractive manufacturing. This process was reliable but designs were limited, lead times were too long, and the costs didn’t always outweigh the benefit. Even worse, some production facilities needed to bond or weld tooling fixtures together which may lead to structural deficiencies and major problems on the manufacturing floor. Using the BigRep PRO, automotive OEMs and suppliers are embracing the ability to immediately build tools that are sized appropriately and require no additional post processing. In this particular case, BigRep prints HI-TEMP CF (carbon fiber) that is built to withstand significant forces with no warping or part degradation. It’s ideal for large parts that require ultimate strength and functionality.

  • High Temp CF is a lightweight material ideal for stiff and durable applications
  • 65 MPa tensile strength
  • Low moisture absorption

BigRep and Forward AM Expand Strategic Partnership with new Material, CONCRETE FORMWORK

3D Printed Concrete Formwork

BigRep and Forward AM, the 3D printing business of BASF, are excited to introduce a new material, CONCRETE FORMWORK, targeted to the architecture and construction industry.

Berlin, Germany. May 10, 2021. Architecture is the representation of a cultural era. By transforming its design language, creators can redefine the world around us. However, reality comes crashing down when conventional formwork solutions quickly reach their limits as construction elements become more complex. To overcome this challenge, Forward AM and BigRep are expanding their partnership and have joined forces again to leverage the synergies between their main areas of expertise: Virtual Engineering, Additive Manufacturing, advanced material development, and large-format printing.

Formwork, the molds used in concrete construction, can make up 40 - 60% of a total budget, especially for complex shapes. Without 3D printing, some designs like organic geometries, double-curved surfaces, and cavities are simply not feasible to produce. They require highly skilled laborers to build customized formwork resulting in high costs, long lead times, and material waste.

“We are excited to work with Forward AM to bring more solutions to the architecture and construction industry,” said Dr. Sven Thate, Managing Director of BigRep. “Our customers are seeing huge gains in terms of cost and speed thanks to our large-format machines and the new CONCRETE FORMWORK filament. Our solutions are opening the doors to many new possibilities.“

BigRep 3D printers, which are up to 1 cubic meter in build volume, can produce large, complex formwork up to 3x faster at a fraction of the cost of traditional methods. With BigRep's new CONCRETE FORMWORK filament enabled by Forward AM, the massive benefits of 3D printed formwork are yours for the taking.

“At Forward AM, we developed a highly dimensionally stable, rigid formwork material, especially tailored to work seamlessly on the BigRep’s large-format3D printers. We are excited to be able to deliver this ready-to-use, end-to-end fabrication solution for bespoke formwork,” says François Minec, Managing Director BASF 3D Printing Solutions.

Demonstrating the material's effectiveness and advantages for the construction industry, Forward AM and BigRep showcase the “Bespoke Stair at Nest Step2,” designed by DBT at ETH Zürich with ROK, SW Umwelttechnik, and WaltGalmarini. The innovative concrete staircase expands the design possibilities of structural architectural elements, while minimizing costs, material waste, and skilled labor. NEST, to be built at EMPA in Zürich, is an innovative building utilizing digital fabrication and circular economy.

4-Hour Parts! Fast 3D Printing in Large Scale

Fast 3D Printing

Fast 3D printing has been the goal of new additive manufacturing technology forever. Unfortunately, when it comes to industrial 3D printers, the size of parts just hasn't been conducive to quick and quality prints. Now, as innovative new technologies hit the market that change the extrusion process allowing industrial 3D printers to produce large-scale parts in just 4 hours, that's finally changing.

A Fast Extruder for On-Demand Solutions

Thanks to the inclusion of BigRep’s proprietary Metering Extruder Technology (MXT®), the BigRep PRO is 3D printing large-format parts in just 4 hours - in this case a manifold for automotive applications. It's able to achieve these exceptional speeds because, unlike FFF, MXT melts filament in advance and stores it in an internal reservoir. The extra step enables unprecedented speed and precision in the printing process by separating the filament melting and material deposition processes, ensuring material passes through the hot end at its ideal temperature and viscosity.

With an identical nozzle size and layer height on a standard traditional 3D printer the parts take 14 hours, a far cry from the astounding 4 hours with MXT. At this speed, the PRO can help fulfill last minute or urgent part requests faster than any other large-format 3D printer. Beyond simply fast production, the full-scale manifolds were 3D printed with exceptionally strong PA6/66 filament (Nylon) - an advanced material with superior layer bonding. Even at speeds 3x faster than traditional FFF technology could produce with a standard PLA material the parts are stronger, breaking across layers before delamination. In urgent circumstances like Kawasaki’s 5-hour fixture for an aircraft cargo door, that kind of quality and on-demand responsiveness is priceless.

When we talk about why you should invest in additive manufacturing the rationale is usually hard numbers: lower costs, faster lead times, and overall increases to productivity. Those are great talking points that speak to the metrics most businesses are looking to improve with a technology investment – or why your boss will be happy you bought a BigRep PRO. But really all of these metrics are just pleasant, measurable effects of how an industrial 3D printer makes your manufacturing operations more flexible. Having the fastest 3D printer in its category, capable of producing engineering-grade parts on-demand at high speed, just extends that flexibility.

The BigRep PRO is our ultimate industrial offering. It provides manufacturers with a variety of features to handle any circumstance you might be faced with. Its massive one-cubic-meter build volume enables the production of exceptionally large parts, or batches of parts that are either all the same or varying iterations. With other built-in quality of life features, like IoT connectivity to monitor ongoing prints and sequential printing to streamline print organization, the PRO gives manufacturers a lot of flexibility in how they want to produce parts. But what makes the PRO really special is that it raises the bar in not just how a part is produced, but the versatility of parts themselves – giving you the power to balance the PRO's enhanced production speed, strength, surface finish and other material properties as you see fit.

An Industrial Machine for Fast 3D Printing

Sometimes speed isn’t your first priority. MXT is unmatched in the fast creation of strong parts but, as a new technology, its compatible materials and resolutions are limited. That’s why the PRO includes BigRep’s fiber-ready Advanced Capabilities Extruder (ACE). It's a traditional FFF extruder for a variety of engineering-grade materials and resolutions to ensure the PRO meets your every need.

The PRO comes stacked with advanced components for faster printing with traditional FFF extruders, too. BigRep’s Precision Motions Portal enables high acceleration and stable printing with high-quality servo motor, a stiffened axis and a unique double rail that evenly distributes the weight of its advanced extruders. Meanwhile a Bosch Rexroth CNC Control System provides elevated responsiveness and repeatability with its 32 integrated sensors and spline interpolation for smooth surfaces. With its top-tier construction, even the PRO’s ACE extruder is capable of printing 1.5x faster than competing industrial 3D printers.

Manufacturing with industrial 3D printers costs less and produces more because they eliminate outsourcing, expensive molds, and all those other inefficiencies of traditional manufacturing. They’re faster because they can run unattended to produce parts in a lights-out manufacturing setting, and because they don’t need any retooling to work. But where industrial 3D printers really shine, and especially the BigRep PRO, is what can’t be expressed so well with metrics. The flexibility that the BigRep PRO brings to industrial manufacturers, from the how to the what, has enabled many businesses to rebalance production for any given task with just a single industrial tool.

BigRep Unveils Two New Industrial 3D Printers With MXT- Metering Extruder Technology

BigRep next generation

Powered by BigRep MXT® and state-of-the-art CNC control systems and drives by Bosch Rexroth, the PRO and EDGE deliver unprecedented speed, precision and quality for industrial applications and full connectivity to integrate additive manufacturing with Industry 4.0

BigRep, the global leader in large-scale 3D printing, today at formnext, the world's leading exhibition for additive manufacturing, unveiled a significant breakthrough in Thermoplastic Extrusion (Fused Filament Fabrication – FFF). BigRep’s new proprietary MXT® will power its two new 3D printers and set a new standard for and redefine additive manufacturing.

The BigRep PRO and BigRep EDGE are the German-engineered company’s next-generation 3D printers, promising to provide engineers and designers with the ability to create functional prototypes, as well as composite tooling, end-use parts and small-number serial production. Capable of printing with high-performance materials, the PRO and EDGE will firmly establish 3D printing as an innovative, added value production technology in industries such as automotive, aerospace, consumer goods, manufacturing and more.

Unveiled on Tuesday, the new printers are embedded with BigRep MXT®, an exclusive Metering Extruder Technology, and equipped with a state-of-the-art Bosch Rexroth motion control system – delivering unprecedented speed, precision and quality and IoT connectivity that fully integrates with Industry 4.0.

BigRep PRO is available to order immediately. BigRep EDGE is scheduled for release in Q2 2019.

“This new technology delivers the type of innovation that the industry has been awaiting, as our groundbreaking MXT® system makes our new printers five times faster – with greater precision and quality – than current extrusion speeds,” said BigRep CEO, Stephan Beyer, PhD. “This is one giant leap for additive manufacturing, allowing BigRep customers to make full use of today’s most advanced large-scale 3D printing technology.”

BigRep PRO is specifically designed for 3D printing of large-scale industrial parts and features a build envelope of one cubic meter and a large, temperature-controlled spool chamber allowing for continuous printing with high-performance materials, like ASA/ABS, nylon and more. The insulated, enclosed metal frame ensures an optimal even temperature control, while glass doors offer a view of the print. The heated print bed is mounted with polyimide foil for enhanced adhesion during the printing process, and an integrated inductive sensor allows for semi-automatic leveling.

BigRep EDGE, with a build chamber measuring 1500 x 800 x 600 mm, is specifically designed for high-end, high performance materials in large-scale format, allowing for end-use parts, functional prototypes and composite tooling. Its heated build chamber provides a controlled, high-temperature environment of up to 200° C in the chamber and 220° C in the print bed. The EDGE also features a premium user experience with automatic, upward-moving doors and an easy-to-use graphical interface on a large screen that enables full control over all print settings.

formnext-2018-unveiling-2

The new technology powering these 3D printers is significant because extrusion technology has largely been unchanged for a quarter-century. The first major advancement is a result of the development partnership announced earlier this year between BigRep and Bosch Rexroth, one of the world’s leading suppliers of drive and control technologies. Through this partnership, the PRO and the EDGE will be the first 3D printers by BigRep incorporating a state-of-art CNC control systems and drives by Bosch Rexroth, making 3D printing a truly IoT-ready machine with full connectivity and data.

Thomas Fechner, General Manager of the Business Unit New Business at Bosch Rexroth, commented: “Thanks to professional control systems technology, 3D printing is establishing itself as an industrial manufacturing application. In terms of hardware, the CNC control system by Bosch Rexroth is delivering the necessary performance, precision and durability. In our development partnership with BigRep, we are advancing the potential of 3D printing for its use in the environment of the Factory of the Future.”

The second major advancement is BigRep MXT®. Unlike its predecessor, BigRep MXT® establishes a clear separation between filament feeding and melting and molten extrusion, which allows for full control over the amount and speed of material extruded at any given time. This new technology is also designed to make full advantage of the innovative printing materials BigRep, in its partnership with BASF, continues to develop.

PRO and EDGE are equipped with two MXT® modular extrusion heads, which manage and synchronize the extrusion and printing operations. This translates into:

  • Printing speeds of >600 millimeters per second (mm/s), when the PRO is used with its finest 0.6 mm nozzle, making it five times faster than any FFF printer on the market. The EDGE surpasses that with speeds of up to 1,000 mm/s with the finest 0.6 mm nozzle in place.
  • Demonstrated filament throughput rate of 5x at the maximum extrusion rate and 3x at the average extrusion rate, compared to FFF technology, delivering material deposition control that allows for unmatched quality, repeatability and precision.

Creating a New 3D Printing Filament – How BigRep Made Pro HT

pro ht

“When 3D printing started, everybody was printing ABS. It is one of the most common materials used in injection molding. Everybody wanted to replicate it in 3D printing.”

Acrylonitrile Butadiene Styrene (ABS) is a thermoplastic, and previously seen as the ideal kind of material for 3D printing extrusion. Using it is not exactly simple though, says BigRep’s Materials Product Manager Markus Bucher, “You need a very controlled ambient temperature to print ABS, which is difficult to achieve. ABS is also not so safe, in terms of the toxic fumes being emitted while melting, so we cannot tweak the machine to reach those temperatures.”

BigRep had plans for printing with a filament stronger than ABS, so the team set about engineering a solution with similar properties. The result: BigRep’s Pro HT.

They managed to find a material with thermal stability comparable with that of ABS, as well as making it easy to handle – it is printable in a similar way to BigRep PLA on the BigRep ONE, in an open build space. Bucher wanted the renewable material to present with good adhesion to the print bed, minimal shrinking and warpage, which they achieved.

Once they had the temperature resistance fixed (115°C) Bucher and the team tested their new material internally, with a new in-house materials verification system. They scouted for materials suppliers and got their certifications in order.

BigRep-car-wheel-rim-mobile-web

As well as designing and manufacturing the highest quality large 3D printers, BigRep is dedicated to material innovation of this kind. BigRep’s materials engineers look in detail at every parameter, consistently fine-tune current materials and when looking to release another 3D printing filament, feedback is always followed by more fine-tuning of the parameters. It is a difficult yet worthwhile process, particularly in the case of Pro HT and engineering-grade materials.

“We were one of the first companies to release a filament with a matte finish, and for that we received a lot of good feedback,” said Bucher, speaking on the positive response from customers who have been happy with the properties of Pro HT. Bucher says the black color filament has been the most popular product in the Pro HT range. It is also available in Nature and Silver colors.

Given its high-level heat deflection temperature, Pro HT is an ideal candidate filament for 3D-printed functional rapid prototyping in industrial settings and is a high-strength, weather-proof filament.

For example, in designing and printing an aesthetically fascinating wheel rim prototype, BigRep Designer Marco Mattia Cristofori says Pro HT was the best filament for the job. “For the angles and declination of the print design, Pro HT properties were ideal,” said Cristofori. “It allowed us to create a highly accurate model for functional testing.” BigRep True Support PVA (water-soluble material) was used with PLA for the rim prototype, then black Pro HT was chosen for the final product, due to its sleek matte finish.

BigRep continually works with clients across a variety of industries on custom material solutions for their individual business applications. As well as the recent release of TPU-based filament Pro FLEX, the materials team has much more in store for the coming months, so stay tuned!

Lean on PVA, When You Need Support

PVA - 3D printing support material

Many of us wish our worldly worries could just dissolve away, but it never seems to work that way. Though if it’s about support structures for large-scale 3D objects, then BigRep’s PVA is the cure for all concerns.

PVA (polyvinyl alcohol) is commonly used in industrial 3D printers with dual-extruders, like the BigRep ONE, to provide support for an object with overhang issues. Some complex prints involving multiple extended overhangs (of over 45°) can only be performed by printing such a support structure. Otherwise, the printed structure would warp or simply collapse – nobody likes that.

BigRep PVA is unlike any other 3D printing filament on the market. It is non-toxic, odorless and easy to extrude, as well as being water soluble. The warmer the water, the faster it dissolves, so users can spend more time creating those tortuous prints and less time refining the results. Moreover, it has been optimized for improved melt flow characteristics, meaning users need not spend their precious time unclogging the hot end. A new video by BigRep shows how easy the process can be, as well as the quality prints resulting from PVA integration.

Wheel Rim

For complex geometries, PVA can be the ideal support structure to enable printing of angles over 45 degrees. Designed by Marco Mattia Cristofori, this 3D-printed wheel rim challenges aesthetic norms for such vehicle parts. The intertwining braces are designed such that they would not be possible with CNC and other traditional methods of milling a wheel rim. Furthermore, for Cristofori’s design, there was no need for manual post-printing curing, sanding, or grinding, thanks to the PVA support – it melts right off the final print.

3D Printed wheel rim

BigRep Longboard

3D printed on the BigRep STUDIO, this BigRep bionic longboard is a model of structural integrity and fascinating aesthetics. It was printed using BigRep PLA with PVA support and integrated carbon pipe, as designed by Beatrice Müller. Once the print had been soaked in water for 20 minutes, BigRep’s team was able to use a soft spatula-type implement to begin scraping the residue off the print.

Longboard

While BigRep already sells a range of high-quality, meticulously engineered 3D printing filaments through its online shop, there is always room for consultation on additional materials. When customers are looking for a specific kind of filament for a custom application, BigRep’s team is pleased to take on the challenge – read more about collaborations between BigRep and Deutsche Bahn, Etihad Airways Engineering and BASF.
