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.{{Cite web|url=https://www.tctmagazine.com/api/content/f30f08ea-f669-11e9-9e86-1244d5f7c7c6/|title=Prusa introduces new $350 MINI 3D printer|last=Griffiths|first=Laura|date=2019-10-24|website=TCT Magazine|language=en-gb|access-date=2019-12-26}}{{Cite web|url=https://all3dp.com/4/prusa-announces-original-prusa-mini-3d-printer-prusa-xl/|title=Prusa Unveils Original Prusa Mini 3D Printer and Announces Prusa XL|date=2019-10-12|website=All3DP|language=en|access-date=2019-12-26}} 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'.{{Cite web|url=https://www.electronicsweekly.com/news/products/emech-enclosures/prusa-cuts-cost-production-prototype-3d-printing-2019-10/|title=Prusa cuts the cost of production and prototype 3D printing|last=Bush|first=Steve|date=2019-10-14|website=Electronics Weekly|language=en-GB|access-date=2019-12-26}}{{Cite web|url=https://all3dp.com/4/mini-prusa-mk3-appears-at-tct-birmingham-2019/|title=Mini Prusa MK3 Appears at TCT Birmingham 2019|date=2019-09-25|website=All3DP|language=en|access-date=2019-12-26}}
Specifications

The Prusa Mini was officially launched in October 2019.{{cite web |last1=Prusa |first1=Josef |title=Original Prusa MINI is here: Smart and compact 3D printer for everyone! |url=https://blog.prusaprinters.org/original-prusa-mini-is-here-smart-and-compact-3d-printer_30887/ |date=2019-10-12}} 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. 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.{{Cite web|url=https://all3dp.com/1/original-prusa-mini-review-3d-printer-specs/|title=2019 Original Prusa Mini 3D Printer: Review the Specs|date=2019-10-14|website=All3DP|language=en|access-date=2019-12-26}}{{Cite web|url=https://3dprint.com/256399/prusa-research-releases-prusa-mini-for-349/|title=Prusa Research Releases Prusa Mini for $349|date=2019-10-14|website=3DPrint.com {{!}} The Voice of 3D Printing / Additive Manufacturing|language=en-US|access-date=2019-12-26}}
It has several safety features including three thermistors to detect thermal runaway.

In November 2020, the Prusa Mini was replaced by the Mini+, which featured a few small updates meant to ease assembly and maintenance.{{cite web |last1=Prusa |first1=Josef |title=November 2020 Update: Original Prusa i3 MK3S+ and MINI+ now shipping, MINI+ kit in the works, new steel sheet available |url=https://blog.prusaprinters.org/november2020_40870/ |date=2020-11-24}} 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|date=November 2022}} The Mini+ filament sensor is an optional extra.

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.{{Cite web |last=Kohut |first=Adam |date=2023-09-20 |title=Original Prusa MK4 Input Shaping Is Here, and the Mini Gets in on the Fun Too |url=https://all3dp.com/4/original-prusa-mk4-input-shaping-is-here-and-the-mini-gets-in-on-the-fun-too/ |access-date=2023-11-26 |website=All3dp}}
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.{{Cite web |last= |date=2019-12-16 |title=Prusa Dares You To Break Their Latest Printer |url=https://hackaday.com/2019/12/16/prusa-dares-you-to-break-their-latest-printer/ |access-date=2019-12-26 |website=Hackaday |language=en-US}} 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).
Reception
Prusa Mini was selected as The Best 3D Printer by The Wirecutter in 2021, and continued to feature until 2023.{{cite web |last1=Brewster |first1=Signe |title=The 3 Best 3D Printers 2021 |url=https://www.nytimes.com/wirecutter/reviews/best-home-3d-printer/ |work=New York Times |access-date=25 June 2024 |date=16 August 2021|archive-url=https://web.archive.org/web/20210816155620/https://www.nytimes.com/wirecutter/reviews/best-home-3d-printer/ |archive-date=16 August 2021 }}
