PET-G is our filament by default. Some other filaments can be installed on MK4S printers. Please read carefully the documentation and ask your coach if you use them for the first time.
Also, never forget to unload and store the filament properly after each print please.
For any other materials, please ask your coach.
Note: Only the filaments you can print on open-access printers are listed on this page.
