The Original Prusa i3 MK3S+ is the last version of our award-winning MK3 3D printer line. We have upgraded the MK3S with a brand new SuperPINDA probe for improved first layer calibration, addedhigh-quality 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!
The functionality of the MK3S+ can be further enhanced by our unique Multi-Material Upgrade 3 for printing with up to 5 filaments simultaneously.
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 avirtual 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 thehigh-quality bearingson 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 areeasy to maintain and make removing the printed object from the print surface a breeze. We offer three types of print surface:smooth, textured and satinto cover all your needs when printing from a wide range of different materials - most of whichdo not require any special separation layersor 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 featuringBondtech 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 powerand 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. Thebuilt-in filament sensoruses 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 theMesh Bed Levelingprocess tocompensate for microscopic imperfections of the print sheet, and inconsistencies caused by the assembly and stacking of the manufacturing tolerances of various parts. Achieving agreat-looking first layer is quick and easy.
Slice with PrusaSlicer
Our internally developed multiplatform slicer comes within-house made and fully tested profilesfor all of our 3D printers and a wide range of filaments. With built-in tools, such asorganic supports, cutting, automated object distribution, ironingand many others, you will turn your 3D models into print files in no time!
Support for a wide range of Materials
The MK3S+ isfully 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 producedurable 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 updatesensure that our machines arepacked with useful features, such as print sheet profiles, automated calibration, Mesh bed leveling, advanced diagnostics, remaining print time estimation, Octoprint support and more!

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-rated3D 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.
If you're looking for your first 3D printer, you like to tinker, or you run a business and want a good reliable machine then look no further than the Original Prusa i3 MK3S.
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.
We offer 24/7 tech support via live chat and email in seven languages. Our printers come with detailed instructions and guides for easy assembly and maintenance. You can also visit our knowledge base, community forum, Facebook groups and official Blog, where we publish useful 3D printing tips and tricks, contests and more!

Advantages of an Assembled 3d Printer
Compared to the assembly kit, the assembled printer differs only in the form in which you receive it.The printer comes pre-assembled and tested right out of the box.To start your first print, simply plug it in, run the initial calibration, and you are good to go. It is anideal choice for businesseswhere there is a need tostart printing as soon as possible.

Upgradability
One of the most popular features of the Original Prusa i3 concept isupgradability. When you buy our 3D printer, you canupgrade it later to a newer version, so you don't need to buy a whole new model every two years like, for example, your phone or laptop. We also keep supporting our 3D printers withregular firmware updates that bring new features!
Ready to print settings
We provide high print settings with the printer, so you don't have to dive into complex new programs the second you finish the build. You can start printing right away, and this gives you a great head start!
These settings are great forall kinds of objects, not just for a couple of prepared showpieces. After a while, when you're familiar with the printer, you can, of course, dive into tinkering ;-)
We are developing our own slicing software.PrusaSlicer is a feature-rich, frequently updated tool that contains everything you need to export the perfect print files for your Original Prusa 3D printer. But of course, we also have the settings for the third party slicers likeSimplify3D,Cura, etc.
