TPU 90A

TPU (Thermoplastic Polyurethane) is a compound of hard plastic and rubbers suitable and mostly used for 3D printing. It is a flexible and elastic material that is incredibly useful for certain applications that require parts to be durable and rubber-like. The surface finish it produces may not be as smooth as some stiffer materials.


TPU elastomer is an engineering-grade material that we chose based on its balance of ease of printing, flexibility, chemical resistance, and toughness. TPU has a hardness of 90A allows you to make very tough, impact resistant and flexible prints. We recommend direct-drive extruders but experienced users can be successful with Bowden-type drives.


Benefits of 3DXFLEX™ TPU 90A Filament:

  • High elongation (>500%)

  • Ease of printing

  • Excellent layer bonding

  • Bonds great to other plastics

  • Outstanding fatigue resistance

  • Very low odor while printing

  • Low moisture absorption

  • Retains flexibility even at low temperatures

  • Styrene and BPA Free

Additional Recommendations

Print in better quality at 210°C nozzle temp with fan on at 40% starting the third layer.
Print at a slow speed.
Cold, sanded acrylic bed recommended. Leave sanding dust on bed for an easier removal.
Keep an eye during the transition between the first layer to second layer, tends to spaghetti out filament out of extruder.
You can tight more the spring arm on extruder to release tension and avoid spaghetti.
