The Original Prusa i3 MK3S+ is here! Featuring a brand new SuperPINDA sensor and design changes to improve the reliability and make the assembly and maintenance easier. We started shipping the first units in November 2020 and you can read all about it here!
The Original Prusa i3 MK3S is the "Best 3D printer" according to All3DP.com and MAKE: Magazine, where MK3S also received "Editor's Choice" as the highest-rated 3D printer in 2019 Digital Fabrication Guide. The MK3S features a rebuilt extruder, numerous sensors, and various smart features. Plus, a new magnetic MK52 heatbed with replaceable PEI spring steel print sheet. Dozens of various tweaks and upgrades improve the reliability and ease of use. The MK3S+ version pushes the reliability and easy of assembly even further.
MK3S+‘s functionality can be further expanded with the unique Multi-Material Upgrade 2.0 addon for printing with up to 5 materials simultaneously.
The most significant new features of Original Prusa i3 MK3S+
The new MK52 Magnetic HeatBed holds replaceable alloy spring steel sheet with PEI surface. You can choose between two types of sheets - smooth PEI sheet and textured powder coated PEI. You can read more about sheets in this article.
With the MK3S+ features Y axis from aluminum extrusion. It provides the same rigidity as some other printers while providing the sleek look of our milled Dural frame. The frame is also optimized to add 10 mm of Z height totaling at 210 mm.
MK3S has two new thermistors. The first one measures ambient temperature on the electronics, preventing MINTEMP errors in rooms with 15°C or less. The second one is embedded in the new SuperPINDA probe, so the first layer will always be spot on!
Did you ever tripped over the extension cord and lost a 20-hours print? MK3S+ will save you! The printer can fully recover from the loss of power. It detects power interruption and shuts down the heatbed and extruder heating. After restoring the power, you can continue with printing.
With MK3S+ we are introducing a completely reworked extruder with a new filament sensor. The new sensor is using the optical sensor which is triggered by a simple mechanical lever. This sensor doesn’t care about the optical properties of the filament (it can be completely invisible) and cannot die because of mechanical wear.
The new EINSY RAMBo motherboard with Trinamic drivers not only makes the MK3S+ silent but it also can detect skipped steps and layer shifting. This is a big step forward for the reliability of the printer and the user comfort. You can say goodbye to ugly prints!
The extruder is now upgraded to Bondtech drive gear. It grips the filament from both sides, increasing the push force and making the printer more reliable, especially for flexible filaments. Also, the print cooling fan now cools part from two sides, increasing the overall performance.
Thanks to the Trinamic2130 drivers and Noctua fan, MK3S+ is extremely quiet in the stealth mode. But also in normal mode is the printer quieter than 99 % of the available printers. In normal mode, we have also increased the printing speed. Now you can achieve more than 200 mm/s!
E3D V6 is market-leading all metal hotend well known for its high-temperature performance. MK3S+ uses a custom heatbreak developed together with E3D. It has proven well its reliability in our Multi Material upgrade and continues to deliver great performance in surprisingly small form factor.

"Of the 11 printers we have tested over the past five years, the Prusa i3 MK3S printer has produced the largest and best-looking prints."
"Test winner: Best device in the test, very versatile, can print in multiple colors. Processes almost everything there is in filament: PLA, ABS, PETG, Nylon, Flex and more." (translated from German)
"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”
"As the test shows, the Prusa Research Original Prusa i3 MK3S did a lot right. It is well processed, has many great features and the printing costs are very low. Especially the print quality is excellent.”
"Designers that rely on 3-D printing as part of their livelihood use Prusa printers to turn out consistent, quality results.These kits contain expertly chosen parts, with an eye on recent technological upgrades.”
"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. ”
"In short. What I don't like about this printer? The rubber feet. What I like? Absolutely everything else!”
"Using this 3D printer has been a joy and an education. (...) The Original Prusa i3 MK3 is highly, thoroughly, and unreservedly recommended.”
"This has a lot of really exciting features that are pushing what the industry is going to be doing.”
"MK3 - highly recommended. I'm really looking forward to everything this printer does becoming standard everywhere.”
"With it's combination of useful new features, along with the reliability and quality of the prints, this is a 3D printer that, especially in the kit form, offers a great price-performance ratio.”
"Josef Prusa and Prusa Research sent over a fully assembled Prusa i3 mk3 3d printer for me to test out and show off on the channel.”
"The smarts, the removable print surface and dependable quality make it perfect for design and prototyping.”
"It is without a doubt the best 3D printer under $1,000 (...) It offers outstanding quality for a reasonable price and comes with a truckload of features.”
