Our next generation webinar was a great success with guests joining from all over the world to listen to Frank Marangell, President of BigRep America Inc, and Abbey Delaney, Marketing Manager, discuss the limitations of old FFF technology, why the additive manufacturing market needed a solution, and what BigRep’s new MXT technology®, which powers our latest industrial printers—the PRO and the EDGE—will do for large-scale, industrial 3D printing.

The webinar closed with a dynamic Q & A session, but unfortunately, we didn’t have time to answer all of your questions, so in this article we will dive deeper into what listeners really wanted to know about BigRep’s next generation 3D printers.

What is the layer thickness options and Z build rate at layer height 1,2,3 etc?

The MXT has all the flexibilities in layer heights of a traditional extruder. Specifically, since the extrusion is very fast, the first release is using a 0.6 mm nozzle, for which we recommend a 0.4 mm layer height—a finer resolution is also possible.

Could you specify the max working extruder temperature for the PRO?

The max extruder temperature is 300C as the extruder is designed for a wide range of materials.

Is the max throughput of 1,000 mm/s reliable for long prints?
Certainly. Both the BigRep PRO and the EDGE were built to print large parts and to run in industrial environments—around the clock. The maximum speed at which the X-Y gantry can move is 1,000 mm/s on the EDGE. The PRO has printing speeds of up to 600 mm/s, with throughput of around 400 cm³/ hour.

What speed and acceleration should xy motors move in order to keep up with these extrusion rates?
The speed and acceleration are dynamically set by the Bosch CNC control system to allow for an optimal printing experience and material performance.

What is the accuracy of the PRO and the EDGE?
The accuracy of the printers is considerably better than their predecessors the ONE and the STUDIO, but the important factor is repeatability: the repeatability is much higher than any other extrusion printer on the market, awakening the potential of large-scale industrial 3D printing.



Could you share more details about the new toolpath generation? What makes it so innovative?
The new toolpath is optimized for high-speed and stability and is currently still in development. Stay tuned to our blog for more details as they emerge.

How much do the printers cost?
If you are interested in receiving additional pricing information, please submit a request here.

How does the internal structure of printed parts appear on the EDGE, as compared to the ONE, in reference to the slide titled ‘how it really looks’?
As the EDGE is pre-beta, we have yet to formally compare the internal structure, but we will publish results in 2019. A study of the PRO will be published early in 2019.

According to the material compatibility table, neither the PRO or the EDGE can use PLA. Can you confirm?
The PRO and the EDGE are industrial materials printers; nevertheless, the target applications for the PRO and the EDGE are in the area of industrial/technical plastics—not PLA. However, the BigRep ONE and STUDIO are PLA compatible.

Is it possible to use two spools of two different types of filaments, using the same fusion temperature?
Although the same melting temperature does not mean the same extrusion characteristics, in general, the use of two different types of filament is achievable, but this needs to be tested and validated, prior to its release.

Regarding materials, are you looking into developing polymers with low CTE, as this will expand the use of AM for aerospace composite cure tooling?
The materials we develop and release in 2019 will unlock new applications for forms and molds—including aerospace applications. With reference to technology and the temperature of the various systems, it all depends on the resin systems used for its components. The curing of parts after production is also possible at 60°C. BigRep is currently speaking with prospective clients to gain insight into their requirements. Knowledge sharing is essential to help advance the additive manufacturing industry.

What printer will PEEK material be available on?
The EDGE—the industry leader for high-end thermoplastic materials.

How do support materials work on BigRep machines?
This is where the second extruder comes in to play: this enables the support material to work. BigRep will introduce special support materials for high-end/high-temp build materials.

Are there any food safe plastic filaments offered by BigRep?
PETG is already available and it is FDA approved ( Furthermore, PP is on the materials roadmap and PC also. FDA compliant BigRep materials: PLA, PVA, ProHT, ProHS, and PETG.
With respect to food safety, the material used is one thing, the complete process of producing food products for consumption is a whole other thing.

What is the max temperature capability of your materials from an end use application perspective?
The max extruder temperature is 450° C or 842° F.

Are the materials listed for the PRO and the EDGE all plastic based or can these be printed with metal?
We are an industrial 3D printing company, specifically a thermoset plastics company. There is no plan to print with metal in the future.

Can this new system work with a carbon filled polymer like Nylon?
We are in the development/testing phase with fiber filled plastics. Watch this space!

Opening a new dimension for Additive Manufacturing

E-Motorbike - Additive Manufacturing Applications


BigRep premieres innovative 3D­ printed prototypes for E‐Mobility and automation applications: showcasing a new dimension of additive manufacturing.

3D printing thought and innovation leader BigRep showcases the world’s first fully (FFF) 3D printed, functional E-Motorcycle and bionic passenger seat, as well as an adaptive robotic gripper and 360° mobile industry platform for automation applications.

Opening a new dimension for Additive Manufacturing, these prototypes designed by NOWLAB the BigRep innovation consultancy, and printed on BigRep’s large-scale 3D printers, include two groundbreaking prototypes for e-mobility applications: the world’s first fully 3D-printed and functional electric motorcycle, the NERA, and a bionic passenger seat, the Aero Seat. Advancing applications in AM are two other new prototypes, the Adaptive Robotic Gripper, designed for flexible handling applications, and the Omni Platform, a 360° mobile industry platform for fully automated manufacturing environments.

"These exciting prototypes not only demonstrate the unprecedented capacity of FFF large-scale 3D printing technology in Additive Manufacturing”, said Stephan Beyer, PhD, CEO of BigRep GmbH. "They also emphasize our unique ability as the market’s innovation and thought leader to bring cutting-edge technologies from design to reality, providing a market value added lead for our industrial customers.”

NERA E-Motorcycle
Lead Design: Marco Mattia Cristofori with Maximilian Sedlak


Using 3D printing technology for cutting-edge e-mobility solutions, NOWLAB has developed the world’s first fully (FFF) 3D-printed and functional e-motorcycle, the NERA e-motorcycle. As a distinction from similar prototypes, all NERA parts, excluding electrical components, have been 3D-printed, including tires, rims, frame, fork and seat.
"The NERA combines several innovations developed by NOWLAB, such as the airless tire, functional integration and embedded sensor technology”, explains Daniel Büning, Co-founder and Managing Director of NOWLAB. "This bike and our other prototypes push the limits of engineering creativity and will reshape AM technology as we know it.”

NERA illustrates the massive benefits that 3D printing offers for the production of end-use parts, particularly for batch sizes between lot size one to small series by reducing lead times and costs, optimizing supply chains, and limiting dependency on supplier networks.

In building NERA, the engineers didn’t simply adapt existing motorcycle designs, but instead envisioned a bike for large-format FFF technology, setting a benchmark for truly creative design; breaking the limits of traditional mechanical engineering. Among the many innovations featured in NERA are the airless tires with customized tread; a lightweight rhomboid wheel rim, flexible bumpers (instead of suspension) and the electric engine, which is fitted in a customizable case.

Aero Seat
Lead Design: Maximilian Sedlak


Another prototype for an e-mobility application is NOWLAB’s Aero Seat, based on aerospace developments and game-changing passenger seat designs for autonomous driving technology. This exciting seat shell design has an almost bionic touch, look, and feel as the seat adapts to the driver’s individual body shape: using a 3D body scan prior to the seat production, the shell will provide its users with an unprecedented level of comfort to reduce the stress and physical discomfort of long-distance travel. Last but not least, flexible material (TPU) was used for printing the seat cushions, which molds to the passenger’s body shape. In addition, they are attached to the shell using only a few fixing points to reduce vibrations.

Adaptive Robotic Gripper
Lead Design: Tobias Storz


The Adaptive Robotic Gripper has been designed to advance the full integration of robotics into automated AM, more specifically to grip finished parts from BigRep printers. Created on a BigRep STUDIO large-scale printer, the bionic gripper is mounted on a robotic arm. The gripper has three modular fingers and an opposable thumb and is capable of handling objects of any shape by wrapping its fingers around it instead of using excess force. It is responsive to pressure with a force-monitoring system that automatically adjusts its grip.
The bionic design of the robotic finger tips is inspired by the lamellae of geckos that help them climb walls. Each finger segment of the robotic gripper has an additional pad made of flexible lamellae. When force is applied these fine rib structures gently hold the gripped object by their restoring force.

Omni Platform
Lead Design: Marco Backenhaus with Mirek Claßen


The equally innovative Omni Platform is a 360° mobile industry platform (size: 100 by 80 cm) for highly flexible applications in automated manufacturing environments and smart factories. It can both serve as an automated logistics carrier (loading capacity: up to 200 kg) and as a platform for additional devices such as robots, for example, to be mounted.

The 3D-printed platform has a fully integrated design, i.e. any bearings or electronics can be integrated during the printing process. Two key elements are special 3D-printed omni wheels with two different materials, allowing the platform to move sideways, and an integrated safety feature (human detection antenna), which was also 3D-printed.

Learning in 3D: Equipping the Next Gen of Engineers & Designers

3D printing and education


We’re excited about this next generation of students finishing their studies with demonstrated practical abilities to use 3D printing technology, and a thirst to change the way we design and build. From the BigRep Innovation Award, which recognizes 3D design talent, to working with universities and students on realizing their complex prototyping projects, BigRep is committed to supporting education about FDM and additive manufacturing.

A new video by BigRep zooms in on three innovative projects that are underway at universities in Denmark, Germany and Britain, all of which exemplify the potential of 3D printing and how it can enhance tertiary or vocational education.

Learning Your 3D ABCs - Large-Scale 3D Printers for Education

One engineering student at Kingston University in London has been designing a 3D-printed injector for a rocket engine and spoke about how the 3D printer has transformed the way designs are developed in real life for testing. Creating a design, producing it, machining it to make changes – this process can be difficult and time-consuming, but the 3D printer makes it easy to develop multiple versions for testing at the same time for a faster turnaround.

One student project has involved using Kingston University’s BigRep ONE to print molds for Caterham racing car parts, such as a carbon fiber door for the driver. As engineering lecturer Dave Haskell says, they print the pieces, which can then go straight into the wind machine for testing.

As Haskell puts it, a main benefit of large-scale 3D printers is that they do not limit your imagination. Practically, you can print big. He says that if there’s any easier way to do it, an engineer will find it. For example, 3D printing is so much easier than trying to make something out of foam. We would also argue, that if there’s a more innovative way of doing something, clued-in students are likely to find it.

At Aalborg University, a pair of students doing their Masters in Offshore Energy Systems are working on a project to create a floating turbine. The blackboard where the pair have sketched out their calculations looks like a jumble of numbers to the average untrained eye, but it represents the working out on a complex design for the 3D printer. They have scaled the design and printed it large scale to test.

For more information and video content on the exciting 3D-printed bicycle project at Aalborg University, which was covered on Plastics Today and All3DP, then click here to watch the bike in action. Just quietly, we’re curious to see whether their frame would work with our world-first, 3D-printed bike tires, printed using our TPU-based Pro FLEX.

The Technical University (TU) Wildau in Brandenburg, Germany, has a BigRep 3D printer that their engineering students use to develop prototypes with different functionalities. In the video, TU Wildau’s FabLab Manager and Ph.D. candidate Markus Lahr, shows a 3D-printed casing for a gear.

He speaks of the great opportunity that large-scale 3D printing technology brings to students to bring their ideas to life in such a formative time in their professional lives and education. An extended video by BigRep offers insight on another student project at TU Wildau, involving printing a bicycle with the BigRep ONE.

Though it is not only university-age students that should be learning about FDM! Guillaume Kouyoumdjian, BigRep’s Head of Online Services, recently gave a presentation on 3D printing to his daughter’s 5th grade class at the bilingual French-German Märkische Grundschule in Berlin.

Using a small 3D printer – for space and time reasons it was not possible to use a BigRep large-scale printer! – Kouyoumdjian showed the young students how to design, slice and print a small object in 30 minutes as part of his presentation. The object was used as part of an interactive story aimed at showing the children how 3D printing could easily reproduce objects. Most of the students had never heard of 3D printing before, and one student exclaimed, "I have so many questions in my head. 45 minutes was much too short!"


Class teacher Ms Bénédicte Sigalas said, “There was a well-established link between the different subjects the children are studying and their daily lives. The presentation on the evolution of past, present and future jobs was very interesting.”

We look forward to hearing how some of these students are changing the face of additive manufacturing a decade down the track!

Your Questions Answered – 3D Printing Webinar Q&As

Picture of 3D printing experts brainstorming about their next architectural project


Our recent webinar ‘How to Revolutionize Your Architecture and Construction Business with 3D Printed Formwork’ was an exciting opportunity for us to connect with other 3D printing, construction and architecture enthusiasts. We had a great group of attendees there on the line asking questions of our webinar hosts, Jörg Petri and Tobias Wallisser. Due to limited time, Petri and Wallisser were not able to answer all questions on the day, so we contacted each participant with answers to their questions afterwards.

Many of the questions were very topical and great opportunities to explain some more context behind the scenes of BigRep and NOWlab projects, and Petri’s view of construction in the future with additive manufacturing. So, we decided to publish the answers here below!

Remember, you can easily watch the webinar for free here.

Can you go over the purpose and type of sensors you are embedding? Are you embedding them in the concrete or the plastic part?

The sensors were embedded in the concrete using a 3D-printed protection ring. We used capacitive sensor technology, so the closer you get with your hand, the stronger the signal. The sensor itself can be printed as well, as we did in another project: The Modular Wall.

Discover our Industrial Use Cases

Can you address cost of 3D printing vs. milling at this scale? We have found machining to be a lot cheaper.

To do a proper calculation, you have to look at the whole process chain. As print times are increasing, this calculation is no longer valid anyway. One of the clear advantages of 3D printing the formwork is less material waste. If you are milling, you will always use a massive block of a low-quality material like styrofoam, the waste for which cannot be easily recycled. After on-site use, the casting element is declared as toxic waste that has to be disposed of at high cost to the producer. In addition to this, you generally have to cover the milled part with epoxy to achieve the necessary strength.

The advantage of 3D printing over milling is that you only use the material you need to form the concrete, and you can print using high-quality polymers that are recyclable. If the strength is sufficient, you can print PLA as a biopolymer – you do not need to recycle it, as it is biodegradable. It is also possible to produce undercuts with flexible materials like a TPU-based filament (Pro FLEX) or a water-soluble PVA.

For each company, the cost and time saved used 3D printing will vary. However, we have found that many customers manage to significantly reduce their time to market. Milling can be cheap, but then can also take up to
several weeks longer than 3D printing molds, for example. So, the saving in terms of resources, material and competitive advantage are substantial. Here is a video providing some examples of time and cost savings that some of our customers have experienced.

Furthermore, the advantage of 3D printing is that it can fit into the production process – it does not have to replace it all together. We find that sometimes customers use traditional milling methods for some parts, while they use 3D printing technology at other stages of the production chain.

Can you also address direct 3D printing of concrete without molds vs with molds?

As mentioned briefly in the webinar, both technologies will play their part on the future building site. The current resolutions for 3D printing do not allow for the production of a visible concrete wall with the necessary surface quality demands.

Furthermore, speed will be an issue. If you reduce the printing resolution,it will be too slow and thus the advantages of using 3D printing are somewhat diminished.

The issue of reinforcement of 3D printed concrete walls is still waiting be solved. That is the advantage of the molding – we are tapping into an existing method and simply changing it slightly. This way, we retain the standards and methods used on-site with in-building pipes, establishing reinforcement, etc. Eventually, this technology and requisite methods will have been developed, but for now, it’s a good start: we’re focused on how replace or optimize some parts in the process chain.

What are the UV properties of BigRep materials? Have you done any testing for outdoor end-use applications?

We are moving through this process currently, to put our latest materials through new tests. We are using modified PLA, which resists temperatures up to 115 degrees Celsius. This is enough for the concrete, which would likely be exposed to the heat from sunlight. Our material development continues, and we will be working on new ones to withstand high temperatures and retain their strength and surface quality. Stay tuned for the end of the year when we have a big announcement surrounding this topic!

Can you develop on formworks recycling process?

We are in the process of testing this right now, to understand the best ways to clean the prints, ensure the safety of any toxic materials etc. So, there is no firm guideline for recycling yet, but it certainly is an important factor in the construction process, as 3D printing moves forward to become an important part of the process.

School is in Session, with Canadian ‘Innovation Enablers’ CAD MicroSolutions

CAD Microsolutions logo


This summer heralds a big change for the rapidly expanding CAD MicroSolutions. They’re looking to move into their new, larger headquarters in Toronto, Canada, which will also serve as their demo facility. As one of the most recent partners to join the BigRep reseller community, they plan to showcase one of our machines on the demo floor – BigRep’s are the first large-scale printing machines they have added to their portfolio of 3D printers.

“BigRep was the sweet spot,” said Hargurdeep Singh, Director of Additive at CAD MicroSolutions. “We were missing the large-build envelope from our portfolio.” He zeroes in on what it was about the technology that motivated them to bring BigRep products to their customers: namely, the open source technology regarding materials and German engineering.

The Canadian firm has been servicing businesses across the country providing mechanical and electrical CAD solutions since 1984. They have expanded into additive manufacturing as well as VR/ AR and IoT solutions. At the helm of CAD MicroSolutions’ additive program, Singh and the team are based in Toronto, with an office in Cambridge and representatives across Canada, including in Montreal and Ottawa. They have a strong technical team, providing both remote and field support, as well as customized training.

Long-time resellers of Solidworks, CAD MicroSolutions was very selective as they expanded into additive manufacturing. They wanted to be sure their technology partners provided solutions that their clients would value. Singh says this has worked to their advantage. He explains that they are now in an advantageous position, being able to pick the solutions that best fit customer needs.

There’s a core focus on education, as training lies at the heart of what they do. Offering webinars, assisting SMEs find funding to explore additive manufacturing potential, and more, CAD MicroSolutions is intent on spreading the word about 3D printing technology. Singh said, “We don’t just want to sell a box,” – it’s ideas and potential they want to offer, as their company tagline ‘Innovation Enablers’ indicates. Students are, in his view, the ‘future force’, as they’re going to make equipment recommendations to their future employers.

The company has also recently partnered with the Canada Makes network, which is a manufacturing industry-led initiative to boost Canadian innovation by encouraging adoption of additive manufacturing technologies. CAD MicroSolutions has seen enormous potential in Canada for shortening production cycles in the furniture industry with large-scale additive manufacturing. Singh said, “It has become very much like the fashion industry – they want to feel, touch, analyze the product. You just can’t do that digitally, so you need a physical, life-sized model in front of you.”


As well as working with the furniture, foundry, and mechatronics industries, CAD MicroSolutions sees the immense possibilities for educational institutions to further explore industrial 3D printing and specifically additive manufacturing. For Singh, it’s personal. “If I hadn’t had the chance to use, to play with them [a 3D printer] at my university, I don’t think I would have the passion and the desire I have today for additive.”

It’s a lucky thing he did come across a 3D printer in his institute, as it spurred the researcher on to win a host of accolades for the papers he has written on the subject, such OACETT’s Best Publication Award in Year 2014, for his paper titled ‘Cost Optimization of FDM Additive Manufactured Parts’. Singh has a technical research and development background, with a mechanical engineering specialty, and joined CAD MicroSolutions in May 2017 to head up their additive manufacturing division.

Fusing Creativity & Technology for Innovation


Some say working in the tech sector doesn’t leave much room for creativity. I beg to differ, and so do most others when they see what my team and I do every day at the intersection of creative and technology. Fusing together art, design and technological innovation has opened up a wealth of possibility for us here at BigRep, and for our customers and partners, in particular.

From an early stage, BigRep decided to have a creative team, and ensure it was a core function within the company. We reached out to designers, architects and artists, and sought interesting collaboration opportunities to demonstrate what large-scale fusion deposition modeling (FDM) could do.

Four years ago, when BigRep started out, not many creative professionals had ready access to 3D printing technology. The awareness level was so much lower than it is now. For us, it was about showing what it really means to use large-scale 3D printing. There’s a difference between doing something large and something that is really 1:1. We took on the exciting challenge of offering more value-added education on what FDM really is, and the potential of it.

In this post, I am keen to give more insights into how we approach our large-scale creative work at BigRep, and why I believe we’ve been pioneering a new-wave approach to creative large-scale 3D printing.

One of our early collaborations was with Munich-based industrial designer Thorsten Franck, on the London table. It is one table that can support a 20-kg plate of glass atop it, and one of the most interesting things about the design is that it can be printed in one loop, in just one day. I think it’s a great example of 3D-printed furniture because it uses the full one cubic meter of the BigRep ONE, it’s made for FDM and designed directly in the G-code, demonstrating big volume at high speed.

We also partnered with Juergen Mayer H. on a project that was about visualizing the code that banks use to disguise information, such as on the inside of envelopes. Given the cavities within the sculpture, 3D printing was the only technology to translate the digital model into a physical reality.

Another creative cooperation on perhaps the largest scale we’ve attempted yet, was with Andreas Greiner, in which the Berlin-based artist took a CT-scan of the skeleton of a broiler chicken and converted it into a skeleton the size of a dinosaur – at a scale of 20:1. Produced in partnership with the Technical University of Applied Sciences (TH Wildau), the seven-meter high sculpture was on display at the Berlinische Gallery, as part of Greiner’s suite of works representing society’s attitude to the meat industry and food production and consumption. It’s fascinating, as an artist myself, to see how our technology can bring a concept to life in a way that has such an impact on a space, and those who view it.

From early on, BigRep wanted to connect to the energy of the city here in Berlin and invest resources in projects that showed the potential of FDM, through film and dynamic content. We wanted to educate, inspire and show what the future could look like – thus the BigRep Innovation Award was born, and launched in October 2017. Starting in partnership with NOVACAD Systems, as a competition for Canadian students to design a chair for 3D printing, we want to help equip the next generation of designers, architects, engineers and artists to develop the skills and know-how to innovate with 3D printing.

I remember what it is like to submit works to open calls and competitions, so my advice for BigRep Innovation Award entrants would be: become familiar with the kinds of technologies available in the 3D printing sphere. Not everything is always ‘printable’, so learn how to design specifically with the technology in mind, and this will yield the best results.

Furthermore, try to be original, and to bring your passion and individuality to the design. Take the time to understand how the technology translates design into digital form and don’t worry about making mistakes. Our large-scale 3D printers are great trial and error tools. You can know in one day how something looks on a 1:1 scale. That changes everything – for design, for art, for creation.

“I raced Amazon Prime, and won.” – The fast-print wonder that is the ‘Kinky Korb’


There are few phenomena quite like the online shopping empire Amazon. The giant online shop offers same-day delivery in Germany and other countries, which many would agree cannot be beaten. Until its delivery time was unofficially beaten – by an in-house BigRep design and The ONE large-scale 3D printer.


It all began with garbage – well, specifically a lack of desk-side recycling receptacles in the BigRep NOWlab office, that is. Mirek Claßen, industrial designer and architect at BigRep’s NOWlab, was on the hunt for more wastepaper bins in BigRep’s Berlin office, and when he saw a few more were needed, he did what many of us would do: he looked online to find some, and saw Amazon’s range available for same-day delivery. But simply ordering some for delivery wouldn’t have been as fun as Claßen’s next idea. “I thought, why not print one, but make it more beautiful, customizable and very print-friendly,” he said. “The idea for the Kinky Korb was born – a recycle bin that fulfils your office needs.”

Named for its quirky shape and the German word for ‘basket’, Claßen designed the Kinky Korb to be sturdy, aesthetically interesting and a fast-print object. “The recycle bin can be printed in vase mode and is tandem machine ready,” explained Claßen. “So, it has a print time of 2.5 hours per item and I bet that’s even better than Amazon’s same day delivery service!”

The design works in every color – in fact, the louder the color, the better! BigRep’s PLA filament comes in a range of funky colors, and the Korb is strong and shiny in the Black PRO HT filament as well. Because it is fast to print, incredibly useful and uses a relatively small amount of filament, the Kinky Korb is the ideal project to test out the BigRep range of colors.

When Jörg Petri, NOWlab’s Head of Innovation, was asked to bring a little give away furniture piece printed on the BigRep ONE at the ‘Mobility Goes Additive’ event in Frankfurt in November 2017, it created more hype than would usually be reserved for a humble paper basket. Passers-by asked to buy one on the spot. This is how the Kinky Korb made its way to the headquarters of German rail service Deutsche Bahn. BigRep has been partnering with Deutsche Bahn on several research and development projects, including one to print headrests as end-use parts. The company put in an order for some colorful Kinky Korbs for their newly refitted office in Berlin.

So, for a quick side project, there are some lively, colorful results when there is a BigRep printer around. Needless to say, all BigRep staff with the standard-issue wastepaper baskets are vying for a funky new yellow, orange, black or green Kinky Korb!

BigRep Innovation Award’s Lindsay Lawson: Bending the Rules of 3D Printing


To create something truly original, sometimes you must throw the rulebook out the window. Berlin-based artist Lindsay Lawson knows all about challenging the boundaries of what is possible, especially when it comes to technology – in fact, it’s an essential facet of her work creating sculpture and other artworks for 3D printing. Lindsay has had her works exhibited extensively across Europe and the United States, where she is originally from. When she is not exhibiting in cities like Vienna, Los Angeles, London or Rome, Lindsay works with BigRep on special projects that challenge its large-scale printers to develop interesting and complex 3D-printed objects.

It was Lindsay’s experience raising artistic works from the 3D print bed, fusing form and function, that made her a clear choice for the jury in the BigRep Innovation Award’s open call to students in Canada. As part of the four-person jury, Lindsay will help decide the ultimate winner of a Canada-wide competition, with a $3,000 cash prize, for the most innovative design of a 3D-printed chair. Following a public vote, a select number of entrants’ designs will be presented to the jury members, who will all be looking for originality, strong understanding of 3D printing principles, aesthetic innovation and structural integrity.

We sat down with Lindsay to find out how she approaches 3D printing in her work, and get her tips for competition entrants.

BigRep: Could you please tell us a bit about how and why you developed your expertise in 3D printing as an artist? 

Lindsay Lawson: My artistic practice is centered around sculpture and video. While my initial foray into 3D modelling was animation, I soon wanted to translate those skills into 3D printed sculptures. Any type of art-making is somehow affected by the tools and materials one chooses to use. With 3D printing the process is how to turn a virtual form into a physical object, and that opens up many new paths to creating something interesting.

BR: With your use of 3D printing technology in your work, how do you balance form + aesthetic with function + structure? What are the challenges you encounter in striking this balance?

LL: The key is to design objects that are particularly suited for additive manufacturing, otherwise it’s like eating soup with a fork. I’m all about printing fast and light so I like to design objects that require no support with minimal infill and few perimeters. Often this means bending some rules of 3D printing – for example, sometimes I like to over-extrude so that I get a thicker wall on a single perimeter print rather than making it double perimeter, therefore cutting the print time in half. But if you’re going to break some rules it’s crucial to design intelligently for the technology you’re using, rather than working against it.

I particularly like to work with some of our more challenging 3D printer materials like transparent PETG, wood filament, flexible TPU. By “challenging” I mean that these materials may not print certain geometries as well as standard materials like PLA. I recently designed some light fixtures that were printed with transparent PETG because the material has a beautiful, silver luster when it refracts light. That project required that I first consider the limitations of FDM in addition to the printability of PETG to inform the functional design of the structure. For me, aesthetic decisions always come last.

How to Submit Your Design

BR: Do you have any words of advice to any students for whom the Innovation Award is their first official design award submission?

LL: If you want to 3D print an object, there is no point in designing something beautiful that can’t be printed. My biggest advice for Innovation Award submissions would be to understand how FDM works and then use the constraints of the technology as a starting point for inspiration.

BR: Which news sources, blogs or publications do you devour for inspiration and industry news?

LL: Since my background is in art, I pay a lot of attention to contemporary art publications and exhibitions, but for design inspiration I like to look at Dezeen and designboom. There are many innovators here at BigRep, so I get a lot of industry news shared from curious colleagues.

Big Inspiration: Marco Mattia Cristofori on furniture design and the Terra Stool

The Terra Stool, a model of furniture design


With a deadline of 11 February, creative young Canadians have just under a month left to submit their innovative 3D-printed chair designs for the BigRep Innovation Award. Over the final weeks we will be interviewing three inspirational design professionals, all 3D printing experts, to spark the creativity and guide the efforts of our competitors on the way towards the finish line.

For the first in the series we sat down with Marco Mattia Cristofori, Product Designer at BigRep, to talk about his latest design, the Terra Stool, which is printed on a BigRep ONE. Marco explains how he developed this intriguing, head-turning piece and gives some handy hints on how best to approach the process of furniture design for production on a BigRep large-format printer.

Could you tell us a bit about your background and experience as a designer?

As an architect who decided to focus on smaller-scale designs, working as a Product Designer at BigRep has opened up new creative possibilities for me. When I started here large 3D prints seemed complex and time consuming to produce, but I discovered that the reality is very different. On our printers you can produce literally whatever you want, only your creativity is the limit and the day after you make a design, you have a prototype. The extra options the printers give me inspire me to move in new directions.

Regarding my background, I’m originally from Italy, and during my formation process I had the chance to live in Spain, the UK, Turkey and before moving to Germany. I worked for two years in an architecture studio based in Istanbul, where I was involved in projects on different scales – from urban planning to furniture design. I discovered that what fascinates me most is designing items for individual use in specific situations, like for sleeping, eating or, in this case, sitting!

How did you approach designing this stool for large-scale 3D printing?

The inspiration for this design was the Ocke Stool which is a really impressive design by Beatrice Müller, a former Product Designer at BigRep. I wanted to re-work the concept in a way which let me experiment with new design ideas and explore what the BigRep machine is capable of. To direct myself I set two constraints: to avoid using any support structure, and to exploit the flexibility of the ‘layer-by-layer’ process of FDM by making every single layer in the design different. An early decision after setting these rules was to have the seat rooted to the print bed which would make avoiding using support structure easier.

Your re-designed stool draws upon natural design/bionic principles? What’s the thinking behind this? 

I decided to use a bionic shape partly because organic shapes tend to vary constantly in their cross-section so this would fit my aim to avoid layer repetition. The beautiful thing is that this typology of design helps to improving the stool’s strength. The gradual curvature of the supporting sections enables this by giving a load applied to the top of the stool an easy path through the object. The sharp angles on rectilinear designs can be weak points which are less able to deal with such forces.

An engineer at BigRep, Paul Worms, showed me some studies and images explaining these bionic principles. If you just look at the way the trunks of trees emerge from the earth, and branches emerge from the trunk, you clearly see this idea of the gradual curvature of structural sections.

What material did you use for this design? What features our Canadian entrants look for when choosing a material?

I chose our most-used 3D printer filament PLA, which allowed a nice polished finish to the seat top when it is printed flat on the print bed. It also meant that I had to limit overhang angles in the design to a maximum of 60 degrees in order to meet my rule of not adding any support material.

I suggest Innovation Award competitors think about other options. For example, it can be nice to use dual extrusion to combine two materials for a new effect, as in [sg_popup id="44" event="click"]this table[/sg_popup] BigRep produced in 2017. In that design we used on of our transparent materials which can produce interesting outcomes, especially if you experiment with infill pattern. Our PRO HT filament is a high-performance ABS-like material, its tensile and impact strength properties open up additional design possibilities.


As a designer, what news sources, blogs or publications do you devour for inspiration and industry news?

I still keep up to date with new developments in architectural design, I really like ArchDaily. I find that I can be inspired by ideas expressed in architectural language, and it influences my product designs. I also really like Dezeen which is more design-focused. And then there is iGNANT! I discovered this around six years ago and it’s a super nice, simple blog that covers different creative media. They’re from Berlin and posted this piece on our colleagues at NOWlab, which is actually about some nature-inspired furniture.

What advice would you give a Canadian student preparing a designs for the February 11 BigRep Innovation Award deadline?

I could talk for hours on this … but let me just say three things. The more research you can do into ideas which inspire you and into 3D printing technology the more likely you can create a really strong, boundary-pushing concept. Also, I would definitely recommend you set some rules for your design and make some quick decisions early on to take some pressure off the process and give a clear direction to your creativity. And the most important thing? Manage your time from there so that you have time to produce a design that expresses your unique perspective, in plenty of time for submission before 11 February!

The Benefits of Using Large-Scale 3D-Printing Solutions

Motorcycle body as a large-scale 3d printing solutions

One of the latest solutions to arise in the 3D printing industry is large-scale printing. Large 3D printers are mostly based on FDM technology and by their nature affordable, easy to use and to maintain. The most popular available material is PLA; easily accessible and with few printing challenges. Additional materials are available with better mechanical properties for more advanced applications.
Now comes the obvious question: who could enjoy the benefits of large-scale 3D printing and what are the benefits of using it?

All parts below were printed with BigRep Large Scale 3D-Printing Technology


Once size limitation is no longer a factor, large parts can be produced at very low cost to simulate large products. Post-processing will bring the final model closer to the original product, and some of printed elements can be used as an end-use product.
