Prusa Research is a Czech 3D printer manufacturer founded in 2012 by Josef Prusa, one of the most influential figures in the desktop 3D printing community. The company's Original Prusa printers, based on the open-source RepRap project, are consistently ranked among the most reliable and best-value FDM 3D printers available. The Prusa MK4, Prusa MINI+, and Prusa XL multi-tool changer are favorites among hobbyists, engineers, educators, and small businesses for their print quality, ease of use, and active community support.
The Prusa online store sells fully assembled printers, DIY kits at reduced prices, and an extensive selection of filaments through Prusament, the company's own premium filament brand manufactured in-house with strict quality control and publicly available quality reports for every spool. Prusa also develops PrusaSlicer, a free and open-source slicing software widely used across the 3D printing community.
