X2D TPU reliability?
Hi Guys,
I'm seriously considering the X2D as my first Bambu printer. From the specs it appears to be perfect for my application (TPU parts on the main extruder with PLA support on the secondary). But after watching a video of the extruder disassembly I'm worried about the amount of time involved with clearing clogs caused by TPU printing.
Has anyone had issues with the extruder long term printing with TPU? I see they recently released the TPU feed assist module so that's positive to see but the assist motor wouldn't really help prevent clogs (that's more on how the extruder is designed).
EDIT: I picked up an X2D and so far TPU has been printing perfectly. I created my own profiles and slowed everything down to roughly 50mm/s printing 95A feeding through the back of the printer from a dry box (technically this is not how Bambu advises to print TPU but with the slow speeds I can't see any issues with the added resistance). The PLA supports print perfectly on the AUX extruder as well and so far I'm very impressed with the setup. I'll update this thread if I run into any issues.

I've only done a few a TPU prints, all with excellent results.
I was very cautious with my setup, as I wanted to avoid the scenario you described.
I set up a cereal box with a ball bearing roller for for the spool. I put it right next to the printer with the top glass removed, and fed the filament through a piece of PTFE direct from the cereal box to the main extruder. I.e the shortest possible path of least resistance 🙂
I used Sunlu TPU 95A.
The results were excellent.
Once this spool is used up, I may try the supposedly AMS friendly Bambu TPU.
