Mini

The Prusa Mini was officially launched in October 2019. The printer is available either assembled or as a kit. The build volume is 180 x 180 x 180 mm, and the print is performed on a spring steel sheet which meant to be easy to remove. Minimum layer resolution is 50 micrometers, and the maximum print speed is 200 millimeters per second. The printer has an LCD color display (non-touch), is able to print via USB drives. It has a custom 32-bit mainboard and a built-in online firmware updater. The printer has sensorless homing using Trinamic 2209 drivers and has a custom hot end which supports E3D nozzles. It has several safety features including three

Mini+

In November 2020, the Prusa Mini was replaced by the Mini+, which had a few small updates meant to ease assembly and maintenance. One of the changes was a new mesh bed levelling sensor called "SuperPINDA" which replaced the previous "MINDA" sensor, and it is claimed by the manufacturer that this should result in a more consistent calibration of the first print layer in particular. The Mini+ also comes standard with the filament sensor, which would otherwise be an optional extra.
