The Original Prusa i3 MK3S+ is the latest version of our award-winning 3D printers. We have upgraded the MK3S with a brand new SuperPINDA probe for improved first layer calibration, added high-quality Misumi 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 MK3S+ is available as an assembly kit, which is the best way to get to know your new 3D printer. Assemble it screw by screw to learn truly everything about its design and how it works! You can also get it fully assembled and factory tested, so all you need to do is to unpack it and plug it in.
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 functionality of the MK3S+ can be further enhanced by our unique Multi-Material Upgrade 2S for printing with up to 5 filaments simultaneously.
Prusa i3 mk3s have received many awards over the years and we keep working hard to make them even better!
WHAT’S NEW IN THE MK3S+
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.
DOZENS OF TWEAKS
With all the cumulative upgrades from the entire MK3’s life cycle on board, the MK3S+ is the best version of our award-winning 3D printer so far. Genuine Gates belts, Bondtech drive gears, EINSY RAMBo motherboard, IR filament sensor, and many other features are the reason why the MK3S+ is the perfect 3D printing workhorse.
WHAT WE ARE PROUD OF…
The most significant features of Original Prusa i3 MK3S+
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.
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.
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.
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.
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.
SILENT AND FAST
Thanks to the Trinamic 2130 drivers and super silent fan, the MK3S+ supports the stealth printing mode, which makes the printer extremely quiet. Even in the normal printing mode, the MK3S+ is quieter than most 3D printers on the market. In the normal mode, the MK3S+ can achieve a print speed of more than 200 mm/s!
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 PLENTY 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!
