Hey everyone,
I’m having an issue with TPU 95A HF. I bought three rolls (grey) from Bambu and loaded them into the H2D as instructed. After a short while, I noticed a light pink powder building up inside the PTFE tube.
When the print finished, I checked the printer and was shocked to see that several components were covered with this powder. At first I thought it might be leftovers from previous prints, so I cleaned everything thoroughly and started another job with TPU 95A HF. But to my surprise, the powder came back.
Since all three rolls show the same behavior, it seems unlikely to be a one-time issue and must be related to the TPU itself.
As for the prints, the powder didn’t cause major problems, but I did notice some small defects where little chunks of it got into the print.
Has anyone else experienced this?
