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.


We recently recieved a Original Prusa i3 MK3 lended to the space by Terry. It is fully functional now, however we still need to discuss on the rules around using this machine since we want to make sure the lended machine stays healthy.
* Please bring your own filament and only use plain PLA.
* For advanced user other filament can be considered. Please see the details section for more information.

**Bed mesh calibration is failing on Lusa, therefore it is currently out of service. <br>
Test to do:

* First Layer Calibration setup with different print bed
** Firmware reflashed
* Characterize print tolerance
** linear rods are cleaned and lubricant applied
 
** rough surface cleaning and screws retightened

** Axis resquared (about 1mm difference still visible after resquaring, but could be compensated by mesh bed leveling)
* Official assembly guide: [https://help.prusa3d.com/category/original-prusa-i3-mk3-kit-assembly_336 Assembly Guide]
** first layer Z-Step recalibrated
* Maintainance guide: [https://help.prusa3d.com/article/i3-printer-regular-maintenance%202072 Maintanance guide]
The Issue should be resolved. During calibration on issue is encountered that occationally the mesh bed leveling only goes to the third position instead of the fourth. If any other print issue is encountered, especially strange behavoir with mesh bed leveling, please report in #3d_printing channel.

We recently recieved a Original Prusa i3 MK3 lended to the space by Terry. It is fully functional now, however we still need to discuss on the rules around using this machine since we want to make sure the lended machine stays healthy.

  • Please bring your own filament and only use plain PLA.
  • For advanced user other filament can be considered. Please see the details section for more information.

Details

  • Build volume 250 × 210 × 210 mm / 9.8 × 8.2 × 8.2 inches
  • Nozzles 0.4mm
  • Avaliable print Surface:
    • Double-sided Textured PEI Powder-coated Spring Steel Sheet
    • Spring Steel Sheet With Smooth Double-sided PEI
  • Printable via SD Card
  • Possible Material: PLA (Recommended) PETG, (ASA), (ABS), PC, CPE, PVA/BVOH, PVB, HIPS, PP, Flex, Nylon
    • For now, please ask the #3d_printing channel in Slack until the detailed rules are worked out.

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 MK3.
  • Get the SD Card that's in the printer, export to the SD Card 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

Specs & calibration

For filament testing please use this Filament Swatch Test to do:

  • First Layer Calibration setup with different print bed
  • Characterize print tolerance

Documentation

Printer repair & maintanance log

  • 02.1.2023 Machine arrived at Lab
  • 10.12.2022 Machine first inspection and maintanance
