We currently have two Original Prusa Minis for basic printing with PLA at the lab. They are called Lusa and Rusa.
- Please bring your own filament and only use plain PLA. Additives like wood or carbon wear out the nozzles extremely quickly.
- Refer to the Whiteboard inside of the Laser & 3D Lounge for currently attached nozzle sizes. By default, there should be one printer with a 0.4 nozzle and one with a 0.6 nozzle.
Details
- Build volume 18 x 18 x 18 cm | 7 x 7 x 7 in
- Nozzles 0.4mm or 0.6mm for 1.75mm Filament.
- Removable magnetic spring steel sheet with PEI surface
- Printable via USB Stick
- Material: plain PLA
Usage
If you haven't used the printer, register for the monthly 3D printing intro course or ask in the 3d_printing channel on Slack beforehand.
- Slice your .stl in PrusaSlicer
- Use the official presets for the Original Prusa MINI. Make sure to adjust the nozzle diameter (see above) And the Filament of choice
- Get the USB stick that's in the printer, export to the USB via the button on the bottom right in PrusaSlicer, and put it back into the printer
- Verify that you're about to start the right print - the display shows an image preview of your model
- You can monitor your print via PrusaControl
