70A Filaflex 500 GR

The Filaflex 70A ‘Ultra-Soft’ is the most elastic and advanced printable filament in the Filaflex range and on the 3D printer market.




The Filaflex 70A ‘Ultra-Soft’ is a polyurethane-based TPE (thermoplastic elastomer) elastic filament with properties comparable to silicone. It has a shore hardness of 70A, meaning that it can stretch by up to 900% before breaking. Its greatest advantage is that after stretching, it returns to its original shape without deforming or breaking.

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.
