The MK4 is the latest edition of Prusa's flagship 3D printing workhorse. It combines the reliability and safety features of its predecessors with high-speed performance enabled by Input Shaper support. It brings plenty of new features like a perfect smooth first layer thanks to the Loadcell sensor (no manual adjustments needed), remote printing, quick-swap nozzles, customizable UI with a one-click printing option, and much more.
