Custom TPU Profile for MK3S – Stock

TPU profile that I think works great. Make sure you loosen your tension a lot. If you try to leave it at the same tension you have use for PLA/PETG you will jam. Try to loosen the tension and then load the filament so you can make sure it loads okay with the little tension.

    Worked well, except I had to raise the temp by ~20c to get the layers to bond preperly

    Dosen’t work in the newer versions of Prusa Slicer so be warned

    What brand TPU is this for? Its set the temp to 220 which doesnt seem hot enough.

    I really want to THANK you for this Custom TPU Profile for MK3S. After months of research, and expressing my concern to Prusa about issues I had heard about with filament jams using TPU with the MK3S, they assured me there would be no issues, so I bought one. Benchy printed great in PLA, but EVERY TPU print failed, with filament jams. I was ready to return the printer, or throw it out the window. Then I came upon your TPU profile, and was amazed when I was suddenly doing beautiful TPU prints! Thank you, Thank you, Thank you!

    Wouldn’t happen to have a custom Nylon profile, would you? 🙂
