The Prusa Mini, stylized as the Original Prusa MINI, is an open-source fused deposition modeling 3D printer that is manufactured by the Czech company Prusa Research.[1][2] The printer is the lowest cost machine produced by Prusa Research and is designed as a first printer or as part of a 'print farm'.[1][3][4]
Specifications

[edit | edit source]
The Prusa Mini was officially launched in October 2019.[5] The printer is available either partially 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.[2] Minimum layer resolution is 50 micrometers, and the maximum travel speed is 200 millimeters per second. The maximum nozzle temperature is 280°C and the maximum heatbed temperature is 100°C. 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.[6][7]
It has several safety features including three thermistors to detect thermal runaway.
Mini+
[edit | edit source]In November 2020, the Prusa Mini was replaced by the Mini+, which featured a few small updates meant to ease assembly and maintenance.[8] 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.[citation needed] The Mini+ filament sensor is an optional extra.
Upgrades
[edit | edit source]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.[9]
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 the PCB, voiding the printer's warranty, before it can be flashed onto the board.[10] This is intended to reduce Prusa's liability should someone create custom firmware with potential to cause harm (such as disabling thermal runaway protections or other safety features).[10]
Reception
[edit | edit source]Prusa Mini was selected as The Best 3D Printer by The Wirecutter in 2021, and continued to feature until 2023.[11]
