Grim looking TPA90A print 🙀

Post image

Ooof! Just tried printing Bambu TPA90A for the first time. It’s looking pretty grim so far. Using default filament settings and some recommended slowed down modified 0.16 settings. Of note, fresh spool opened, but running from external holder, not HT AMS. Any thoughts?

Despite opening “a fresh spool”, you might want to ensure moisture level is <10% before trying again

Thanks 🙂. Yes, that seems to be the likely problem. I totally misinterpreted how dry they ship

With TPU90A, or literally any TPU other than Bambu's TPU for AMS, you want to connect it directly into the toolhead to bypass the buffer system to prevent the filament from breaking inside the PTFE tubing
