3D Printed Rubber. TPU.

TPU Rubber Like

TPU is an ideal 3d printed material for producing large and complex flexible parts. Durable, complex parts have never been easier to 3D print, helped by the use of a support system where the support is either dissolved or falls away. 

Typical applications include 3d printed seals, flexible ducts and hoses, tubes and damper pads and blocks.

TPU. FDM.

FDM TPU 92A gives you a tough, durable material with high elongation and good abrasion resistance.  As per the name, the material has a Shore A hardness value of 92 on the A scale. 

• Build Volume: 355 x 254 x 355 mm
• Surface Finish: Lightly ridged.  
• Good Detail from 0.256mm (256um) layers with finer layer options.
• Minimum recommended feature detail or wall thickness of 1mm.
• Flame Classification, UL94, HB and V2. 
• Black

TPU. SLS.

SLS TPU has a Shore A hardness value in the 81 region while giving you excellent surface finish. The powder support and finer layer height allows for good detail while parts can be watertight assuming suitable wall thickness. 

• Build Volume: 300 x 300 x 300 mm
• Surface Finish: Smooth.  
• Good Detail from 0.1mm (100um) layers with finer layer options.
• Minimum recommended feature detail or wall thickness of 0.8mm.
• Off White.
