Product Description
Prusa MK4 is the latest edition of our 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.
The MK4 will consistently deliver a perfect smooth first layer thanks to the Loadcell sensor (no manual adjustments needed). The next-gen extruder (Nextruder) and 32-bit connected platform provide many quality-of-life improvements like remote printing, quick-swap nozzles, and customizable UI with a one-click printing option.
The package includes a Smooth PEI print sheet.
