All proven features of the previous models included

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!

The functionality of the MK3S+ can be further enhanced by our unique Multi-Material Upgrade 2S for printing with up to 5 filaments simultaneously.

By purchasing the assembled MK3S+ you gain free access to our online course and, in addition, you enter our discount program; 10% for selected filaments and 10% for all subsequent orders of assembled MK3S+ printers.

Alternatively, you can try the full "Prusa Experience" with the printer kit, which you will assemble by yourself (it takes around 8 hours), and learn more about how the printer works.

Main Features of the Prusa i3 MK3S+

SuperPinda Probe: SuperPINDA probe features a high-quality sensor for a fully-automatic Mesh Bed Leveling process. Before every print, the printer probes the bed in several places and creates a virtual heightmap of the print area. This process ensures that the first layer will always be spot on!

Quality Bearings & more: The MK3S+ features a new set of metal clips for the high-quality bearings on the Y-axis. The belt tensioning mechanism on the X-axis was reworked and the X-end plastic parts reinforced. The filament path in the extruder was altered for better support of flexible filaments.

Removable Print Sheets: Spring steel sheets are easy to maintain and make removing the printed object from the print surface a breeze. Prusa offers three types of print surface: smooth, textured, and satin to cover all your needs when printing from a wide range of different materials - most of which do not require any special separation layers or surface preparation.

High-Quality Parts: The MK3S+ features an aluminum extrusion Y-axis assembly. Thanks to the milled dural frame, the MK3S+ is stable, rigid, and easy to assemble. Combined with Prusa's internally developed extruder featuring Bondtech gears and the E3D V6 hotend, the MK3S+ can print high-quality objects up to 210 mm in height.

Main Features of the Prusa i3 MK3S+ (continued)

Power Loss Recovery: Are you afraid of a blackout ruining your 48-hour print? Worry no more - the MK3S+ can deal with that! The printer can fully recover from the loss of power and continue printing exactly where it left off. It detects power interruptions and shuts down the heatbed and extruder heating, and saves the last known location.

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.

Mesh Bed Leveling: Thanks to the SuperPINDA probe, the MK3S+ can use the Mesh Bed Leveling process to compensate for microscopic imperfections of the print sheet, and inconsistencies caused by the assembly and stacking of the manufacturing tolerances of various parts. Achieving a great-looking first layer is quick and easy.

Slice with PrusaSlicer: Prusa's internally developed multiplatform slicer comes with in-house made and fully tested profiles for all of its 3D printers and a wide range of filaments. With built-in tools, such as advanced support generation, cutting, automated object distribution, ironing, and many others, you will turn your 3D models into print files in no time!

Support for a wide range of Materials: The MK3S+ is fully compatible with a wide range of various types of materials. No matter whether you want to print something for fun from PLA and flexible materials, or you need to produce durable prototypes from PETG, ASA, Polycarbonate, and Polypropylene - the MK3S+ can handle them with ease.

Open-source Hardware & Firmware: We develop firmware for all of our 3D printers and test every new version thoroughly before release. Ongoing development and regular updates ensure that our machines are packed with useful features, such as print sheet profiles, automated calibration, Mesh bed leveling, advanced diagnostics, remaining print time estimation, Octoprint support, and more!
