    Main Features


    SuperPinda Probe

    SuperPINDA probe features a hiqh-quality sensor for a fully-automatic Mesh Bed Leveling process. Before every print, the MK3S+ 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!

    Misumi Bearings & more

    The MK3S+ features a new set of metal clips for the genuine MISUMI 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. We offer 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 our internally developed extruder featuring Bondtech gears and the E3D V6 hotend, the MK3S+ can print high-quality objects up to 210 mm in height.

    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

    Our internally developed multiplatform slicer comes with in-house made and fully tested profiles for all of our 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!

    Original Prusa MMU2S Upgrade

    Multi Material Upgrade 2s (mmu2s) is the second generation of our unique multi-material addon, which enables your 3d printer to print with up to 5 colors at the same time.
