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.

The printer has sensorless homing using Trinamic 2209 drivers and has a custom hot end which supports E3D nozzles.

In November 2020, the Prusa Mini was replaced by the Mini+, which featured a few small updates meant to ease assembly and maintenance.

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.
