Can the Bambu Lab A1 print TPU?
Fits, with limits
The maker lists TPU as ideal for the A1, with two limits in Bambu's TPU guide: the AMS lite cannot feed ordinary TPU, and the A1 series cannot print TPU 85A.
Limits
- Ordinary TPU cannot be fed through the AMS, AMS lite or AMS 2 Pro. Bambu's own 'TPU for AMS' filament is the exception.
- TPU 85A: Bambu marks it incompatible with the A1 series. Its table marks TPU 90A, TPU 95A HF and TPU for AMS as compatible.
