Original Prusa i3 MK3S+ kit
Original Prusa i3 MK3S+ kit
The Original Prusa I3 MK3S+ is the successor of the award-winning Original Prusa i3 MK2 3D printer. With the rebuilt extruder, a plethora of sensors and the new magnetic MK52 heatbed with replaceable PEI spring steel print sheet we believe that we've developed our best 3D printer yet!
This listing is a DIY KIT for self-assembly.
Continuous development of the Original Prusa i3 MK3 and MK3S leads us to the enhanced and improved Original Prusa i3 MK3S+ released on November 24. 2020 and announced on PrusaPrinters.org
SuperPINDA is temperature-independent, it features a much higher quality sensor and better quality components overall comparing with the P.I.N.D.A. v2, plus, it does not need a thermistor. A combination of all these enhancements ensures the first layer will always be spot on!
MISUMI BEARINGS & MORE
We now have a new set of metal clips for the MISUMI bearings on Y-axes. They are easier to mount and provide better support for the bearings. X-axes belt tensioning mechanism was reworked and X-end plastic parts reinforced. Extruder changes provide better printability for flexible filaments.
DOZENS OF TWEAKS
MK3S+ includes all the cumulative upgrades from the entire life cycle of the MK3 like genuine Gates belts, textile sleeves, a new Einsy case for easier Raspberry Pi connection, an anti-rust coating on smooth PEI sheets and, of course, dozens of firmware and plastic parts enhancements.
The Original Prusa i3 MK3/S+ is the "Best 3D printer" according to All3DP.com and MAKE: Magazine, where MK3/S+ 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 a replaceable PEI spring steel print sheet. Dozens of various tweaks and upgrades improve the reliability and ease of use. MK3S‘s functionality can be further expanded with the unique Multi-Material Upgrade 2S addon for printing with up to 5 materials simultaneously. Below, you can see some of the many 3D printer awards Prusa Research received.
WE ARE PROUD OF...
The most significant features of Original Prusa i3 MK3S+
The new MK52 Magnetic Heatbed holds a replaceable alloy spring steel sheet with a PEI surface. You can choose between two types of sheets - smooth PEI sheet (default option) and textured powder coated PEI.
With the MK3S+ we are introducing the reworked Y axis from 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.
NEW FILAMENT SENSOR
The previous sensor didn’t work well with some specific filaments. 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 and cannot die because of mechanical wear.
SILENT & FASTER PRINTING
Thanks to the new Trinamic2130 drivers and Noctua fan, the MK3S+ is extremely quiet in the stealth mode. But the MK3S+ is quieter than 99 % of the available printers, even in the Normal mode. In normal mode, we have also increased the travel speed. Now you can achieve up to 200 mm/s!
Have 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.
BETTER SERVICE & PRINTS
Thanks to completely reworked extruder changing the nozzle or PTFE tube is easier than ever before. As a bonus, the nozzle and the extruder motor is much closer to the X axis, this means less resonance and better prints too. MK3S is also better for printing from flexible materials.
PREVENTS SHIFTED LAYERS
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 in the reliability of the printer and the user comfort. You can say goodbye to ugly prints!
The extruder has now upgraded with Bondtech drive gear. It grips the filament from both sides, increasing the push force and making the printer more reliable. This is useful for flexible filaments. Also, the print fan now cools part from two sides, increasing the overall performance.
E3D V6 NOZZLE
E3D V6 is market-leading all metal hotend well known for its high-temperature performance. The MK3S+ utilizes a developed together with E3D. The reliability has proved in our upgrade and continues to deliver great performance in surprisingly small form factor.

With 3D printing, buying a printer is just a beginning!
Fun to assemble
Assembling the kit is an excellent first step to the world of 3D printing. You will understand the principles of printer construction and get a huge advantage when you need to solve possible problems and replacements later.
But don't worry. Assembling is quite easy! You don't have to solder at all to build our kit. You don't even have to own a soldering iron. All our cables are cut to length and with professionally crimped connectors. And from the electronics standpoint, the hardest thing will be plugging the connectors to the motherboard.
All of this makes the kit very friendly to younger builders :-)
Best assembly instructions and free 3D Printing handbook
We didn't want to leave anything to chance, so our assembly instructions are pictured to the smallest detail.
All fasteners and mechanical parts have 1:1 drawing so you can easily find them, and there is no chance of you picking a wrong one. You don't have to be MIT graduate to assemble our kit ;-)
Our fastest customer built the kit in 4 hours! Will you beat him?
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
One of the most popular features of Original Prusa i3 concept is upgradability. If you buy our 3D printer, you can upgrade it later to the new version, so you don't need to buy the whole new model every two years as you get used to for example with your phone or laptop. :-)
Upgrades are a great way not only for saving money, but also to learn about the construction of the printer's hardware. We are constantly improving our technology. A few years ago there was the Original Prusa i3 3mm which was upgradable to the Original Prusa i3 Plus 1.75mm (MK1). MK1 printer can become MK2S thanks to the next big upgrade and then you can go even for the latest MK3S+ (or MK2.5S if you wish).
Discount program for Original Prusa i3 kit owners
Our discount program for the Original Prusa i3 kit owners gives you a 5% discount on subsequent orders of selected filaments, including the high-precision Prusament!
How does it work?
To enter the discount program, you only need to purchase your first Original Prusa i3 kit for the full price. After the i3 kit is delivered to you, your Prusa account automatically applies the 5% discount on the selected filaments. So next time you'll be stocking up on filaments you can take advantage of the 5% discount :-). Make sure to be always logged into your Prusa account, to have the discount applied.
Ready for the Multi Material Upgrade 2S
Original Prusa i3 MK3S+ is the unique consumer option to print with up to 5 different materials simultaneously. MMU2S comes with a redesigned body and a new filament loading mechanism. Instead of the previous Bowden system. The motorized selector head has a F.I.N.D.A filament sensor and a built-in blade, which prevents filament jamming.
Multi-material could be your next step in the 3D printing world and MK3S+ is completely ready for the upgrade.
BTW: Do you know, that you can easily print soluble interface supports with upgrade? We have a pretty smart solution for you - check out the video
