The Prusa i3 MK3S 3D printer kit is a successor model of the renowned i3 series, offering users the opportunity to assemble their own high-quality 3D printing system. This kit includes all the necessary components to build a reliable desktop 3D printer with the original design from Prusa Research, developed by Josef Prusa. The printer housing and components are in black, providing a professional appearance for workshop, educational, or home environments. With a build volume of 250 mm x 210 mm x 210 mm, this printer allows for a wide range of printing projects from prototypes to functional parts. The kit integrates the MK3S upgrade package with an improved filament sensor, redesigned extruder unit, and enhanced cooling system for consistent print quality. Assembly requires basic technical knowledge and about 6-8 hours, with comprehensive online documentation and community support available. The printer uses 1.75 mm diameter filament and supports various materials including PLA, PETG, ABS, and flexible filaments. Key features include automatic bed leveling, power recovery, filament end detection, and a removable magnetic print bed with a PEI coating for reliable adhesion. The printer operates with a layer resolution of 0.05 mm to 0.35 mm and a maximum print speed of 200 mm/s. The kit includes all electronic components, motors, bearings, printed parts, and necessary hardware for complete assembly. The dimensions of the assembled device are approximately 500 mm x 550 mm x 400 mm with a weight of about 7 kg. This kit is designed for users seeking a customizable 3D printing experience with the reliability and community support of the Prusa ecosystem.
