Prusa Research: all devices

Prusa Research is a Czech manufacturer of FDM and resin printers with headquarters and production in Prague. The company grew out of the open RepRap project, develops its own slicers, firmware and filament (Prusament) and runs the Printables model platform. The devices are more expensive than comparable printers from China, but are considered well documented, repairable and maintained over the long term.

Pros and cons of Prusa Research

Facts

History

Josef Průša, previously a developer in the RepRap project, founded Prusa Research in Prague in 2012; the i3 series (most recently MK4S) became one of the most copied printer designs. Later came the MINI, the large multi-tool model XL, the SLA printer SL1S and, in 2024, the enclosed CoreXY printer CORE One, as well as the professional Prusa Pro series after the acquisition of Trilab. According to its own sustainability report, Prusa built around 122,700 printers in 2023 (2022: around 101,200) and produced 610 tonnes of Prusament filament. At the end of 2024, according to its own annual review, the company had more than 1,000 employees; according to Wikipedia, revenue in 2020 was around 2.18 billion koruna. In 2022 Prusa acquired the US filament manufacturer Printed Solid in Delaware, which now operates as Prusa USA, makes filament there and assembles the MK4S and CORE One (as of July 2026). Prusa is privately owned and not listed on the stock exchange.

Customer support and warranty

Support is provided through a live chat in the shop and in the knowledge base, staffed around the clock in English, and by email in German, English, Czech, Spanish, French, Italian and Polish, with a reply within up to three working days. Shipping and service come directly from Prague, so from the EU; Prusa sells spare parts in its own shop, and there are detailed repair guides in the knowledge base. For printers, a warranty extension of 1 to 2 years (MINI+ only 1 year) can be added at purchase; for second-hand purchases, according to the manufacturer, 1 year applies from the first delivery, with wear parts such as nozzles, belts and PTFE tubes excluded. On Trustpilot, Prusa has a rating of 4.5 out of 5 from around 10,000 reviews (as of October 2026); documentation and support are praised, while sometimes long waiting times in chat and for emails are criticised.

Environment and commitment

Prusa publishes sustainability reports; the report for 2023 mentions, among other things, smaller shipping boxes (MINI+ from 53 to 33 litres) and a map of collection points for 3D printing waste, but contains no currently measured carbon footprint (last figure from 2021). With Prusa Education, the company has offered schools teaching projects and a 5% discount on printers since 2020 (internationally since 2022). PrusaSlicer is open source (AGPL-3.0), and older printers were released completely openly. The printers are designed to be repairable, with public guides and spare parts in the shop.

Criticism and problems

Prusa has been moving away from open hardware step by step since 2023; the CORE One is no longer fully open, which parts of the community criticise. In July 2025, Josef Průša declared open-hardware desktop 3D printing "dead", citing patent applications by Chinese manufacturers on ideas from the open community, including an Anycubic patent that resembles his MMU1 design. New products repeatedly arrived late: the XL was announced in November 2021 and only shipped from March 2023, and in 2023 MK4 variants and the MMU3 were also delayed. In the Prusa forum there are 2025 reports of incomplete CORE One upgrade kits and slow follow-up deliveries, but also of quick solutions; a systematic problem has not been documented.
