Filling in the Filament Blanks


To truly harness the potential of FDM technology, a few things need to fit together in a neat puzzle: the hardware (the machine) needs to work tirelessly and with accuracy; the software must function seamlessly; the 3D printer materials need to be of high quality and suit the nature of the print project. For industrial 3D printers, the stakes become higher when printing large-scale objects for either prototyping or end-use. In these situations, the printing time is longer and therefore printing failures can waste valuable time and money.

To ensure this triad of quality is complete, and that its high standards for hardware, software and innovation are complemented by the best printing materials, BigRep develops its own 3d printer filaments for its large-scale printers. We toil over a new generation of high-thermoplastic materials that are suitable for industrial applications. Only when 3D printers and materials are developed side by side, can it be possible to ensure optimal stability and high quality results.

Over the coming weeks, we will dive deeper into each kind of filament that BigRep produces to learn more about their mechanical properties, possible applications and share some tips and tricks on how best to use and post-process them to achieve superb large-scale parts.

We marry up German machinery with self-developed dedicated thermoplastics, offering a powerful solution for producing large objects for both concept and functional prototyping. Innovation is central to the BigRep philosophy, so there are numerous R&D projects currently running to develop exciting new filaments for its materials portfolio, which currently includes:


Perfect solution for prototyping, art projects, producing end-use parts and rapid tooling applications. This filament extrudes very well and has very low moisture absorption.

One example of how BigRep PLA can be used was demonstrated by BigRep customer Geiger, with its concrete casting formwork. Our e-book on this use case provides further details on the use of this filament for a complex building restoration.

Our experts with +25,000 hours of experience in industrial 3D printing are waiting to sink their teeth into your unique and challenging use case.


BigRep PVA is a water-soluble support filament. The warmer the water, the faster it dissolves, so users can spend more time creating prints and less time refining the results.

The PRO HS is a robust biodegradable material matching the mechanical properties of BigRep’s PLA. However, its distinguishable by its particularly high extrusion rate, which enables large-scale 3D printing at higher speeds.

PETG is characterized by its strength, toughness and thermal resistance, as well as very low warping behavior – it is a real alternative to ABS.
