Original Prusa MK4 is built around our new 32-bit connected architecture and the next-generation extruder (Nextruder). It lays down a perfect first layer every time without Live Adjust Z and it has support for high-speed printing with Input Shaper and Pressure Advance. We also improved the safety features even further. Plus, there are a ton of useful things, such as quick-swap nozzles, built-in support for remote printing and webcams, and many more. And it’s still beautifully quiet.
Main Features
Thanks to our own implementation of Input Shaper and Pressure Advance technologies in the MK4’s firmware, the printer can eliminate resonance in prints and predict the flow of the filament. The result is a decrease in print time by up to 70% in comparison with MK3. What's more, the printer is very quiet even at these speeds. Support for high-speed printing will be added later via a firmware update.
Thanks to the precise Loadcell sensor, MK4 can lay down a perfectly smooth and consistent first layer automatically without any user input. At the beginning of a print, the printer taps the sheet with the nozzle in a grid-like pattern to measure the distance and then calculates the correct offsets. The result is a perfect first layer on every surface, without manual adjustments.
Extruder is the heart of every 3D printer. And this is a special one. On most 3D printers today, replacing extruder components is a rather complicated process. With the new connector break-out board inside the Nextruder, all of the parts, such as fans, heaters, thermistors, etc., are connected directly there. If you need to swap anything, it takes just a minute.
Our new xBuddy board is a 32-bit STM32-powered mainboard with many great features. It has several unique hardware-based safety protection systems, communicates with four thermistors, has all important ports (Ethernet, Wi-Fi, works with USB-A flash drives) and more. The entire board was designed, manufactured, and tested in-house.
The MK4 comes with redesigned, more robust plastic parts and new precise 0.9° stepper motors (0.9° / step; low inductance) on the X and Y axes that help eliminate Vertical Fine Artifacts on prints. Plus, there are thicker 10mm rods on the Z-axis. The result is, that prints look better than ever and even printing with “problematic” filaments like Flex is a breeze.
MK4’s display supports G-code thumbnails, QR codes and other elements that make using the printer so much easier. We also redesigned many of the existing menus and added a customizable footer panel. Directly under the LCD, there is an RGB status bar to signalize the current status of the printer. Next to the LCD, there’s a USB-A port for standard USB flash drives.
Thanks to two quick-release thumbscrews on the side of the body of Nextruder, which holds the nozzle in place, you can swap nozzles easier than ever. The MK4 is using special nozzles with an all-metal filament guide (no PTFE tubes anywhere), which improves the overall reliability of the printer. Simple Nextruder-to-V6 adapter is available.
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 organic supports, cutting, automated object distribution, ironing and many others, you will turn your 3D models into print files in no time!
The MK4 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 MK4 can handle them without any problem.
MK4 is, along our other 3D printers, fully supported by Prusa Connect, which allows you to control the printer via internet. You can drag-and-drop G-Codes into the browser window to upload print files first into the cloud (each user gets 2 GB for free) and then transfer it into the printer’s USB storage and start the print remotely. All communication is encrypted.

* Consumable parts, such as print sheets (smooth, textured, etc.), are not covered by the warranty since their coatings are expected to deteriorate over time, unless the failure is due to a defect in materials or workmanship. Cosmetic damage, which includes, but is not limited to, scratches, dents, cracks, or other aesthetic damage, is also not covered. Only sheets defective upon delivery are covered by the warranty.
MK4 can be enhanced by an optional add-on that allows your single-extruder printer to print with up to 5 colors (materials) at the same time. The MMU3 contains five filament insertion points. Load the five colors of your choice, slice the object with MMU3 profile in PrusaSlicer and start the print. The system automatically selects filament using the selector, loads it into the Nextruder and the MK4 starts printing. When it’s time to change the color or material, it also happens automatically.
The MMU3 is the latest edition of Multi Material printing device by Prusa Research. The firmware has been rewritten completely, we have redesigned the plastic parts, added more robust metal parts, improved the electronics and updated the filament buffer. All of these changes have improved the reliability and user comfort to levels where MMU has never been before.
MK4 is fully compatible with the Original Prusa Enclosure. If you want to print more advanced technical materials on your MK4, you’ll find the Enclosure really handy. It stabilizes the printer environment, eliminates drafts and odors, and makes the printer even more silent.
