TPU on the Prusa MK4
Yes, easily. Open-frame bed slinger, famously dependable and repairable.
TPU prints great on the Prusa MK4
Direct drive, good for flexiblesPrinter
The Prusa MK4’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.
Nothing special neededPrinter
The Prusa MK4 handles TPU without extra equipment. Load it and print.
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.
