FDM material
TPU 85A (Soft Flexible TPU) 3D Printing
Softer than our standard 95A TPU, closer to a pencil eraser or shoe sole. Grips, seals and cushions better, compresses more easily, and absorbs more vibration. Slower to print, which is reflected in price.

TPU 85A: common questions
What is TPU 85A good for?
TPU 85A is a common choice for soft seals & gaskets, grips & handles, vibration dampers, wearables. Softer than our standard 95A TPU, closer to a pencil eraser or shoe sole. Grips, seals and cushions better, compresses more easily, and absorbs more vibration. Slower to print, which is reflected in price.
How strong and heat-resistant is TPU 85A?
Printed TPU 85A parts have a typical tensile strength of 20–35 MPa and heat resistance of ~70 °C. These are typical values for printed parts in the XY direction; strength between layers is lower, so orientation matters for loaded parts.
How big a part can you print in TPU 85A, and how fast?
Up to 350 × 320 × 325 mm in one piece; larger parts are printed in sections and joined, after a review. Production takes 2-5 business days, and rush service is available.
