Why Choose 90A Over 95A TPU?

TPU filaments come in different Shore hardness ratings that determine how stiff or flexible the finished print will be. At 90A, Eryone TPU is softer and more elastic than the more common 95A options, so printed parts stretch further, compress more easily, and absorb impact better.

That extra softness suits parts where flex and cushioning matter most — gaskets, seals, vibration dampers, soft-touch grips, wearables, and protective covers that need to squish rather than resist. If you need a firmer part that holds its shape under load, or you’re printing on a Bowden setup where softer filaments are harder to feed, 95A is the safer pick. A direct drive extruder and slower print speeds will get the best results from 90A.

Printing Tips for TPU 90A

TPU requires slower print speeds and a direct-drive extruder for reliable results. Bowden setups can work but often cause buckling and inconsistent extrusion due to the flexible filament path. Print at 200–220°C with the bed at 25–60°C — many users find no heated bed is needed at all.

Keep retraction distance short (0.5–1.5 mm on direct drive) and retraction speed low to avoid jamming. Slow down to 20–30 mm/s for the first layer, then 30–50 mm/s for remaining layers. Disable or reduce part cooling fan for the first few layers to improve bed adhesion.

Dry TPU before printing — moisture causes bubbling, stringing, and poor surface finish. Dry at 60°C for 4–6 hours, or print directly from a filament dryer for best results.

Not Compatible with Bambu Lab AMS

TPU filaments are not compatible with the Bambu Lab AMS or AMS Lite due to the flexible nature of the material. Use an external spool holder mounted on top of or beside your printer and feed the filament directly into the extruder. The Bambu Lab A1, P1, and X1 series all support external spool feeding.

Available Colours

Choose from six options: Black, White, Grey, Transparent, Transparent Red, and Transparent Blue. The transparent variants produce semi-translucent prints that look great for light diffusers, decorative covers, and display pieces.
