  3. Press the knob and gently pull out the filament.
  4. You can find PLA filament above the printers. Please ask if you are unsure whether you can use a filament.
  5. Please make sure that you use PLA (type of filament)!
  6. Cut the tip of your filament (the one you want to use) at a 45-degree angle before inserting it into the printer.
  7. Before loading the filament, insert it by pushing it gently from above into the nozzle.
  8. To load the filament, go to Load filament.
  9. Push the filament gently until the printer starts pulling it.
  10. You will be asked whether the filament is extruding and with the correct color. Press Yes if everything is fine and No to extrude more filament.
  11. Remove the extruded filament from the nozzle and the steel sheet.


Set up PrusaSlicer

  1. To use the printer, you will need an application which converts the 3d model into a file that can be interpreted by the printer.

  5. Skip this step as you do not need a profile for using this application and click on Next >.
  6. Please select only the sources from Prusa and click on Next >.
  7. Scroll down to MK3 Family and select Original Prusa i3 MK3S & MK3+ 0.4 mm nozzle.
  8. Then scroll down to Legacy profiles Family, select Original Prusa MINI & MINI+ 0.4 mm nozzle and click on Next >.
  9. We do not have those printers, just click on Next >.
  10. Unselect the checkbox and click on Next >.
  11. Make sure that Generic PLA is selected and click on Next >.
  12. Please skip automatic updates and click on Next >.
  13. Select build-in downloader if you want to open models from printables.com and click on Next >.
  14. Select this checkbox if you want to export full pathnames and part sources into your 3mf files. Then click an Next >.
  15. Select Export mode to see the whole settings in the app and click on Finish.
  16. Now an empty project will be created where you can add your model. Select 0.20mm QUALITY from the dropdown of Print settings.
  17. Set Filament to Generic PLA.
  18. Select the printer you are using. In this case select Original Prusa i3 MK3S & MK3S+
