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.
Suplied as a DIY kit, we can assemble it for you, just choose the option bellow.
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.
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.
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.
With the MK3S we are introducing the reworked 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.
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.
P.I.N.D.A. 2 Probe
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 PINDA 2 probe to compensate temperature drift. So the first layer will always be spot on!
Silent & faster printing
Thanks to the new 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!
Recover 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 for the reliability of the printer and the user comfort. You can say goodbye to ugly prints!
E3D V6 nozzle
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.
