TPU on the Snapmaker J1
Yes, with a couple of cautions. Enclosed with two independent print heads (IDEX) for two-material jobs.
TPU works on the Snapmaker J1, mind a couple of things
Feeding quirk on this printerPrinter
Snapmaker supports TPU of 90A hardness or firmer on the J1.
Direct drive, good for flexiblesPrinter
The Snapmaker J1’s motor sits right on the print head, which is what soft filament needs. Keep speed down around 20-40 mm/s and turn retraction low.
Keep the spool dryMaterial
TPU soaks up moisture from the air, and damp filament prints rough and stringy. If that happens, dry the spool at 50-60 °C for 6-12 h and store it sealed with desiccant.
Safe starting ranges for TPU as a family, not gospel. Each spool below has its exact manufacturer numbers, the dated source, and one-click slicer settings on its page.
