Filaflex 70A, 'Ultra-Soft', is a highly elastic TPU (thermoplastic polyurethane) flexible filament whose properties make it comparable to silicone.

It has a 70A shore hardness, reaching up to 900% stretch before breaking. Its greatest advantage is that after stretching, it returns to its original shape without deforming or breaking.

Filaflex 70A is not suitable for All Metal hotends, since the filament could get stuck and not flow properly, however, if you have any questions, contact us and we will advise you.

The filaments of the Filaflex range have great print bed adhesion, so they don’t need a heated bed, blue tape, Kapton tape, lacquer or any other spray adhesive. What’s more, they are odourless and resistant to solvents, acetone and fuel. Different guidelines are required for printing with Filaflex. That’s why the 3D printer needs to be properly configured.

How to get started with Filaflex? First of all, we recommend this article on how to print with flexible materials written by Steve Wood of Gyrobot.
