Prusa i3 MK2S 3D Printers

The Digital Media Fab Lab is equipped with four Prusa i3 MK2S filament extruding desktop 3D printers from Prusa Research.


All four of these 3D printers are designated to exclusively extrude PLA and PLA-blend filaments. PLA (polylactic acid) is a biodegradable thermoplastic created from plant-starch and a monomer catalyst. PLA filament is available for student projects, but if a specific color, blend, or quantity is required, consult the lab manager for purchasing recommendations.


*Temporarily Unavailable* Prusa #1 has an optical filament sensor that detects the presence and movement of filament. This is the ideal printer for long-duration prints, as the sensor monitors when filament runs out, automatically pauses the machine, unloads remaining filament, and waits to be reloaded. If printing with a lighter colored filament, be cautious as sometimes matte white, ivory, translucent, and lime green can falsely trigger the sensor. If necessary, the filament sensor can be disabled in the LCD Menu under Settings.


Prusa #2, #3, and #4 are standard MK2S printers and will print any color of PLA, or PLA-blends such as wood, bronze, brass, and conductive filament types.

To prepare a file for 3D printing, utilize PrusaSlicer, which can be downloaded for free on both Macs and PCs. PrusaSlicer is available for use in the lab, however preparing your file ahead of time will expedite the 3D printing process.
