Flexible TPU FAQ

Are there any printing requirements?
A direct-drive extruder for 85A and 90A; 95A and above print on most Bowden machines at reduced speed. Dry the spool at 55 °C for 4 hours if it has been open more than a few days.
What is the difference between 85A, 90A, 95A, 98A and 72D?
Shore hardness. 85A is the softest (running-shoe sole), 95A is the all-rounder (cart wheel), 98A is firm (tyre tread) and 72D is hard and abrasion-resistant (hard hat). Softer grades print slower and need direct drive.
How strong is TPU?
Tensile strength is 30 MPa across the ladder; what changes is stiffness and elongation, from over 1100 % at 85A to over 700 % at 72D.
Will the spools work in an AMS?
Only 72D. Bambu Lab lists TPU below 55D as unsupported in the AMS feed path, so print 85A–98A from the external holder.
Where are the TDS and slicer profiles?
Every product page has a downloads block with Bambu Studio, OrcaSlicer and PrusaSlicer profiles plus the technical data sheet. All profiles are also listed on the Profiles page.
