Polymaker PolyFlex TPU90 0.75kg 1.75 mm
Soft TPU filament for flexible and elastic FDM/FFF 3D printed parts
Product Description
Polymaker PolyFlex TPU90 is a particularly flexible TPU filament for elastic components such as seals, protective covers, flexible connectors, grips or other functional printed parts.
With a Shore hardness of 90A, TPU90 is softer than TPU95 and is particularly suitable for applications where high flexibility and a soft feel are required.
For reliable results, a direct drive extruder is recommended. For Bowden systems, adjusted speed, retract settings and clean filament guidance are particularly important.
TPU is sensitive to moisture. The filament should be stored dry and, if moisture is absorbed, dried in a suitable filament dryer or drying device before printing.

Frequently Asked Questions about TPU Filament
What is TPU filament used for?
TPU is used for flexible parts such as protective covers, seals, grips, feet, dampers and components that need elasticity.
Is TPU filament flexible?
Yes. TPU is a flexible filament. Depending on the exact hardness, it can be used for soft, rubber-like or slightly flexible parts.
Is TPU difficult to print?
TPU is more demanding than rigid materials such as PLA or PETG. Slower print speeds, dry filament and a well-guided filament path help achieve reliable results.
Does TPU need a direct-drive extruder?
A direct-drive extruder is recommended for TPU because it controls flexible filament more precisely. Some Bowden printers can also print TPU, but usually at lower speeds.
Why should TPU be printed slowly?
Flexible filament can compress or bend in the filament path. Slower print speeds reduce feeding issues and improve dimensional accuracy.
How should TPU filament be stored?
TPU should be stored dry and protected from humidity. Moist TPU can cause stringing, bubbles and rough surfaces during printing.
