Shore hardness
How soft does it need to be?
The lower the value on the A scale, the softer the filament. TPU for AMS is rated on the D scale and is the firmest.
TPU for AMS · 68D
The firmest: it flexes but feels solid. Ideal for protective cases and impact-resistant parts.
TPU 95A HF · 95A
Flexible and tough: a good all-rounder for cases, bumpers and flexible parts.
TPU 90A · 90A
Softer, with enough structure for soles, tyres and protective gear.
TPU 85A · 85A
The softest: ideal for absorbing shocks and for anything you want to squeeze.

How to get the most out of your TPU
Always dry it
TPU absorbs moisture easily. Dry it before use, for TPU 85A and 90A for example 8 hours at 70 °C, and store it airtight below 20% humidity.
Loading and unloading
Print TPU 95A HF, 90A and 85A from the external spool holder. With TPU 85A and 90A, don’t press Unload: heat the nozzle to 250 °C and pull the filament out by hand.
How flexible will your print be?
That also depends on your settings: fewer walls and a lower infill make your print softer and more flexible.
The right build plate
Print TPU on a Smooth PEI or Textured PEI plate with a little glue. Your print sticks well and comes off easily afterwards.
FAQ
Frequently asked questions
Which TPU should I choose?
If you want to print flexible parts with the AMS or combine several colours, choose TPU for AMS. For flexible parts without the AMS, TPU 95A HF is a good all-rounder. If it really needs to be soft, choose TPU 90A or TPU 85A.
Does TPU work in the AMS?
Only TPU for AMS works in the AMS and the AMS lite. TPU 95A HF, TPU 90A and TPU 85A are too flexible for the AMS: print them from the external spool holder.
Which nozzle do I need?
A 0.2 mm nozzle doesn’t work with TPU for AMS, TPU 90A or TPU 85A. For TPU 85A, use a 0.6 or 0.8 mm nozzle. Note: TPU 85A is not suitable for the A series.
Can I combine TPU with PLA or PETG?
Yes, you can combine Bambu Lab TPU with PLA or PETG in one print, for example for a hard housing with a soft grip. With TPU for AMS, this happens automatically via the AMS.
Can I order a colour that is out of stock?
No, you can only order what is actually in stock. Each product page shows how many units of each colour are available. If a colour is temporarily unavailable, ask to be notified on the product page or get in touch with us.
