Original Prusa i3 MK3S+ 3D Printer

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.

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.

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.

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.

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.

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 organic supports, cutting, automated object distribution, ironing and many others, you will turn your 3D models into print files in no time!

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.

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!

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.

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.

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!

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!
