We currently prefer PrusaSlicer for our printers in the Lab. This is how to use it


  • Download the latest version here
  • Install
  • Launch

Add Printers

  • PrusaSlicer should open the configuration wizard on its first launch automatically. If it doesn't (or you've closed it prematurely) you can open it again by clicking "Configuration => Configuration Assistant"
  • If you only want to print on the Prusa Minis, you can click "Finish" right away - the presets for this printer are selected by default.
    • On "Prusa FFF" you can add presets for more nozzles (e.g. 0.6) or other printers.
    • By default, presets for generic filament and Prusament are selected. If you bought some third-party filament, you can see if "Filaments" has a preset for it.
    • Make sure that "Check for application updates" and "Update built-in Presets automatically" are checked on the "Updates" step

We have configurations available for the more advanced printers (e.g. Ultimaker_Unlimited_Z). If you really actually need them you can ask for them in the 3d-printing channel on slack.

Congratulations! You're now set up to use the Printers!


This section is stolen from the 3D Printing Handbook. You should reference it directly if any questions arise in the future (as you hopefully have been instructed to).

The Interface

PrusaSlicer Interface.png
  1. The Add button loads models into PrusaSlicer
  2. Delete and Delete All buttons remove the model(s) from PrusaSlicer
  3. Opens the detailed settings of print, filament, and printer
  4. Move, scale, rotate, Place on Face and cut tools
  5. Slice and generate .gcode button
  6. Quality / Speed setting of a print
  7. Material selection
  8. Printer selection
  9. Right-click on model opens a context menu
  10. Switch between 3D editor and layers preview
  11. Model preview
  12. Switch between Simple / Advanced / Expert mode

Basic Usage

  • Use the Add button to load your STL (or use fusion to directly handover to PrusaSlicer)
  • Add Supports if you need to (again, see the 3D Printing Handbook for more info)
  • Select the right printer if you have multiple profiles (Rusa/Lusa on the top shelf are Prusa MINIs)
  • Select the Filament type that you want to use
  • Plug the USB stick from the Printer into your PC
  • A second button next to the "(5) Slice and generate .gcode button" should have appeared => click that
  • Give it a useful name and save
  • Another Button should have appeared down there => click it to eject the USB stick
  • Proceed with pre-print setup as you have been instructed
