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 travel 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.

Mini+
In November 2020, the Prusa Mini was replaced by the Mini+, which featured 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+ filament sensor is an optional extra.Upgrades
In September 2023, Prusa Research announced that upcoming Mini and Mini+ firmware would include network remote management using the PrusaConnect service, and input shaping for faster printing with no physical changes to the printer needed. The printer is the first open source hardware product to require a user wishing to use unsigned firmware to physically break off a piece of thePCB
