Flexible TPU

Whether you want a super soft phone case, or you want to add some impact resistance to your hard plastic print - TPU has you covered.

Flexible TPU FAQ

Are there any printing requirements?

It can depend. TPU95-HF can print on any printer since it has high flow capabilities, but TPU90 is very soft and will require a direct extruder with a good gear ratio.

Trying to print TPU90 on a Bowden setup will likely lead to extrusion issues.

TPU95 is in-between and it is possible to print on a Bowden setup - but you need to print very slowly.

What is difference between TPU90, TPU95, and TPU95-HF?

The number refers to the shore hardness of the material. Shore hardness works via the smaller the number, the softer the material.

This means that TPU90 would be our softest option with a shore hardness of 90A.

TPU95 has a shore hardness of 95A.

TPU95-HF is a bit closer to being a shore hardness of 98A rather than 95A, meaning it is the hardest of the 3 TPU options we have.

What is TPU95-HF?

PolyFlex™ TPU95-HF, created from Covestro’s Addigy®️ family, is a TPU with high flow properties making it ideal for high speed printing. PolyFlex™ TPU95-HF unlocks new applications for flexible materials in manufacturing.

How strong is TPU?

TPU options are EXTREMELY impact resistant and have phenomenal layer adhesion. It is going to be near impossible to break a TPU print by dropping it or throwing it at a wall.

The good layer adhesion though does make it difficult to use parent support material, since it is hard to remove after printing.

Will the spools work in an AMS?

This is hard to answer. While we have redesigned the edges of our spools so all Polymaker products will now spin great in the AMS - TPU is often too soft to feed into the AMS properly.

Use TPU in the AMS with caution - we suggest avoiding it.
