Excellent Printer Compatibility

Yes, there are already a few flexible filaments out there. However one thing we notice about those materials is their poor compatibility with different 3D printers. Many of them only work on one specific printer model or extruder type – and you have to bet on your luck that it works on the one you have. Some of them only work on 3 mm printers – to our knowledge there has not been a flexible filament that works consistently on 1.75 mm 3D printers.

Therefore we had a clear goal in mind: to develop a soft and flexible filament that is compatible with most desktop 3D printers - a material that everyone can use. That goal was achieved by carefully designing and optimizing the melt-flow properties of the material, and thoroughly testing the material on a large variety of printers. We are proud to announce that our PolyFlex is available in both 1.75 and 3 mm, and is compatible with most (if not all) desktop FDM/FFF 3D printers, including: MakerBot Replicator 2, Replicator 2X, Ultimaker (and several of its variations), RepRap Prusa Mendel, MakerGear M2, Afinia / Up! Plus , and many more as we can’t list everything here.


Fast Printing Speed

The biggest challenge with soft filaments is that they often lead to problems with feeding, as the material can be too soft to generate enough pressure. One compromise one often times has to make is slowing down the printing speed significantly. However this is almost not necessary for PolyFlex – for example our normal printing speed is in the range of 60 – 90 mm/min. Furthermore, PolyFlex requires no heated build plate and has very little tendency to warp (better than PLA and ABS).


Endless Possibilities

The soft and flexible nature of PolyFlex offers a new dimension of what one can do with desktop 3D printers. We showed a couple examples in our video, but you can do much more with PolyFlex: toys, seals, prosthetics, shoes, belts…the possibilities are really limitless. PolyFlex also features very high printing quality and gives great details.
