Prusa Research

Prusa Research a.s., commonly referred to as Prusa, is a Czech company that produces 3D printers, and was the world's second largest 3D printer manufacturer in 2020. It was founded in 2012 by Josef Průša, a developer in the RepRap project which has a strong emphasis on open-source hardware. In the past, all printers produced by the company were open source – their design plans were fully available online and anyone could use them, for example to improve an existing printer. Some examples are the Prusa i3, Prusa Mini and Prusa XL. As of 2023, the company started partially abandoning this open-source concept due to competition from others (including their open-source software being used by competitor Bambu Lab), and in 2024 launched their second CoreXY printer Prusa Core One which is no longer fully open-source.
