More stable frame

The new frame is on the Y-axis is made of aluminum profiles, providing greater rigidity. Milled frame from duraluminim was also optimized for field work by adding 10 mm along the axis C - axis C range is 210 mm.

Quick and quiet printing

New drivers Trinamic 2130 and fan Noctua make the MK3S+ printer very quiet in the Stealth mode, but even in normal mode it is quieter than 99% of commercially available printers. In normal mode, it also has an increased print speed, now it can reach even more than 200 mm/sec.

3D printer Prusa i3 MK3S+ - quiet and fast.

Power Panic

MK3S+ can resume printing after a total loss of power. Detects a break in power supply and disables the heating table and the extruder, after the resumption of power it resumes printing.

Mode of resuming printing after power loss.

Filament sensor

The optical filamentu sensor detects not only its presence but also its movement. Prusa MK3S+ can detect the tip of the filament, pause the print and ask the user to load a new coil. It can also detect the lock of filament in the nozzle and repoty the need for its restoration.

Recover shifter layers

The new EINSY RAMBo motherboard with Trinamic drivers not only makes the MK3S+ extremely quiet but it also can detect skipped steps and layer shifting. You can say goodbye to messy prints!

In addition, the motherboard has special inputs to connect the Raspberry Pi Zero, expanding the function of the printer with the wi-fi interface OctoPrint.

Bondtech Extruder

The printer has an upgraded 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.

Upgraded Bondtech extruder.

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.

Probe SuperPINDA in 3D printer Prusa i3 MK3S+

TheSuperPINDA leveling sensorhas been designed to be as insensitive as possible to temperature changes. The advanced design and the highest quality sensor allowed to eliminate the thermistor from the sensor design. SuperPINDA ensures that the first layer of the model will always be printed the same.

The product is top from Prusa. I would give it 5 stars but since they put a premium on the printer, 1 point is deducted. Prusa products are the best 3D printers in their class. Cheaper printers can't do anything, more expensive printers are therefore three times as expensive. We have 20 of them in use and also MK4, so we know what we're talking about. Our printers run 200-250 days a year and there is rarely anything to complain about.

thank you very much on behalf of my Dreamer and the Mam Marzenie Foundation for the quick fulfillment of my dream and packing the gadgets that made me happy. The product rating is very good.
Jaroslaw 12.04.2023 Confirmed purchase Translated review
I was a little afraid to take the kit for self-assembly due to the fact that it is my first 3D printer. But I must admit that the manual is written really well with attention to detail. I folded the printer for 3 days, where two days for the assembly itself and the last day for calibration and testing. One note is take your time because it's easy to skip key instructions and spread it out over more days. In my opinion, the prints come out really decent and I'm glad that I got to know its structure during folding.
Adam 26.01.2023 Confirmed purchase Translated review
The quality of the printed elements in the Prusa set leaves much to be desired compared to the ender 3 whose elements are incomparably better. So the quality for the price is not great. The standard appearance of the printer itself as a solid. Usability comparable to the ender.
Krzysztof 15.12.2022 Confirmed purchase Translated review
It takes a little patience and a few or several hours to put everything together. Then calibrate and that's it. It has been printing for several days without any problems and without the need for settings. Cool!

Easy to assemble, understandable menu. Good for the first printer.
Dionizy Ś. 02.03.2021 Confirmed purchase Translated review
This is my first 3D printer. The purchased version for self-assembly is a good starting solution and allowed me to get acquainted with the construction of the device - which will bring positive results in the further maintenance of the printer. The device itself and all elements are very well made. The manual for the device is great and allows you to go through the assembly process without any problems. The print quality is very good - I had the opportunity to compare my printouts with those of people who have other devices. After the first few weeks of using the device, I am completely satisfied.
