The Prusa I3 MK3S is a kit printer that you can assemble yourself. It was developed by Czech manufacturer Josef Prusa, who made a name for himself in the additive manufacturing market with his first Prusa I3.

This device is an evolution of the first Prusa I3 MK2S, which is one of the most popular desktop 3D printers on the market due to its ease of assembly and modification.
