The Original Prusa i3 MK3S+ is the latest version of Prusa’s award-winning 3D printers. The upgraded MK3S has a brand new SuperPINDA probe for improved first layer calibration, added high-quality, Misumi bearings and various useful design tweaks to make the printer easier to assemble and maintain. The MK3S+ includes all the proven features of the previous models, including the heatbed with removable PEI spring steel print sheets, automatic Mesh Bed Leveling, filament sensor, power loss recovery (power panic) and safety features. While still staying as silent as ever!
This version is an assembly kit, which is the best way to get to know your new 3D printer. Assemble it screw by screw to learn truly everything about its design and how it works! Perfect for when you need to do maintenance down the road
Thanks to all of these (and many other) features, the MK3S is voted the best “Best 3D Printer” by ALL3DP. The MK3S is also the highest-rated 3D printer, and the “Editor’s Choice”, in the prestigious MAKE:MAGAZINE’s Digital Fabrication Guide 2019. The MK3S is also featured in TechRadar’s Best 3D printers of 2021 as The best all-around 3D printer. NY Times wrote that “…of the 11 printers we’ve tested over the past five years, the Prusa i3 MK3S printer has produced the largest and best-looking prints.”
The functionality of the MK3S+ can be further enhanced by our unique Multi-Material Upgrade 2S for printing with up to 5 filaments simultaneously.
