MK3S+ Kit is the latest version of our award-winning 3D printers. We have upgraded the MK3S with a brand new SuperPINDA probe for improved first-layer calibration, added high-quality bearings, and various useful design tweaks to make the printer easier to assemble and maintain. The MK3S+ 3D Printer includes all the proven features of the previous models, including the heated with removable PEI spring steel print sheets, automatic Mesh Bed Leveling, filament sensor, power loss recovery (power panic), and safety features.
