This is a fully assembled printer.

The Original Prusa i3 MK3S+ 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 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. And it is still as silent as ever!

Thanks to all of these (and many other) features, the MK3S became the “Best 3D Printer” according to 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." 

Our printers have received many awards over the years and we keep working hard to make them even better!

FILAMENT SENSOR

The MK3S+ further enhances the reworked extruder from the MK3S. The built-in filament sensor uses a reliable trigger system, which detects whether a strand of filament is inserted into the extruder. It can detect any type and color of filament and is not susceptible to mechanical wear
