Prusa i3

The Prusa i3 is a family of fused filament fabrication 3D printers, manufactured by Czech company Prusa Research under the trademarked name Original Prusa i3. Part of the RepRap project, Prusa i3 printers were called the most used 3D printer in the world in 2016. The first Prusa i3 was designed by Josef Průša in 2012, and was released as a commercial kit product in 2015. The latest model (Prusa MK4S on sale as of August 2024) is available in both kit and factory assembled versions. The Prusa i3's comparable low cost and ease of construction and modification made it popular in education and with hobbyists and professionals, with the Prusa i3 model MK2 printer receiving several awards in 2016. The i3 series is released under an open source license, which has led to many other companies and individuals producing variants and clones of the design. The i3 moniker refers to the printer being the third iteration of the design. It was used up until the Prusa i3 MK3 and its variants but was dropped from the model, Prusa MK4.
