Original Prusa i3 MK3S+ 3D Printer

Main Features

SuperPinda Probe

 

SuperPINDA probe features a hiqh-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!

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!

Technical Parameters

* Consumable parts, such as PEI sheets (smooth, textured, etc.) are not covered by warranty as the coatings are designed to diminish over time unless failure has occurred due to a defect in materials or workmanship. Cosmetic damage, including but not limited to scratches, dents, cracks, or other cosmetic damage is also not covered by the warranty. Only defective sheets on arrival are covered by warranty.

Awards & Press Reviews

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." According to ZDNet, the MK3S is "The best pro-sumer 3D printer under 1000 USD."

  The preassembled version of the Original Prusa i3 MK3S is a cinch to get up and running, is easy to operate, and has a good slicing program. It produced consistently beautiful prints in our testing, with no misprints.

  You can get under the hood and tinker with this or change that, but you don’t have to. MK3S is a printer that ‘just works’ for beginners, yet is still powerful enough for advanced use. 10/10

  We tested it using its default settings and found it extremely capable. Its print quality is truly exceptional and it’s an easy-to-use, straightforward machine.

  The team at Prusa Research have made something special with the MK3. If you only ever own one printer, make it this one. Of course, once you buy it you will want more of them, and that's ok too.
