The Filaflex 82A ‘Original’ is the flagship elastic filament of the Filaflex range. The best-selling and most popular flexible material for 3D printers.




The Filaflex 82A ‘Original’ is a polyurethane-based TPE (thermoplastic elastomer) elastic filament with a shore hardness of 82A, meaning that it can stretch by up to 650% 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.

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.

– Prostheses and models of organs: prosthetic arms and hands, organs for simulation of surgical operations, etc.

– Flexible objects and parts for manufacturing and the automotive industry: stoppers, joints, tyres, grippers, etc.

– Textile parts and accessories: textile garments, fabrics, prints on garments, bags, earrings, etc.

– Footwear: soles, shoes, sandals, slippers, etc.

Technical Data

Technical Data


Print temperature: 215-250 °C
Print speed: 20-60 mm/s
Diameter tolerance: 0.03 mm
Retractions: from 4-8 mm/s to 40 mm/s. In the extreme case of a clogged extruder, make sure you disable retractions.
Increase the flow if the extrusion of the filament is intermittent, between 105 % – 115 %.
Reduce the pressure of the lever arm that presses the filament onto the motor pulley to avoid clogging the filament and causing blockages.
