Original Prusa i3 MK3S+ 3D printer

The printer includes one Smooth PEI Sheet.

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 (30 spools per year) and 10% for five units of assembled MK3S+ printers in subsequent orders.

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, added high-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

Super Pinda Probe

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 height map of the print area. This process ensures that the first layer will 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. 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 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.

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."

      6 reasons to buy the MK3S+


      Great User Support

      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 an ideal choice for businesses where there is a need to start printing as soon as possible.


      Built-in Safety Features

      Original Prusa 3D printers are well-known for their reliability and safe operation. Every part of our printers is thoroughly tested in-house. The MK3S+ is equipped with three thermistors and comes with a custom-built high-quality Delta power supply. The printer can recognize issues with heating and stop operation to prevent damage.


      Open-source and Community Friendly

      All parts of our printer are open-source, which means we publish all source codes and blueprints online. The community around our products is huge and the feedback is overwhelmingly positive - don't believe us? Check out Facebook groups and YouTube videos! There's so much to do with your 3D printer - buying it is just the beginning!


      Ready for the Multi-Material Upgrade 3

      Multi-Material Upgrade 3 is our unique add-on option for printing with up to 5 different filaments simultaneously. Multi-material could be your next step in the 3D printing world and the MK3S and MK3S+ are completely ready for the upgrade! MMU3 also allows you to print a soluble support interface.



      One of the most popular features of the Original Prusa i3 concept is upgradability. When you buy our 3D printer, you can upgrade 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 with regular firmware updates that bring new features!

      Printed Solid Service Center USA: I would also like to share that we have created a new Repair Center at our subsidiary branch - Printed Solid to accelerate the repair of our Original Prusa Printers within the USA. Please take a look at our Knowledge Base in detail.


      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 for all 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 like Simplify3D, Cura, etc.
