Main Features


High-speed printing with ease

High-speed printing with ease

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% compared to MK3. What's more, the printer is very quiet even at these speeds - check out the sub-20-minute Benchy video

Perfect First Layer on a First Try

Perfect First Layer Out of the Box

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.

The Nextruder with Breakout Board

The Nextruder with Breakout Board

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.

32-bit xBuddy Mainboard

32-bit xBuddy Mainboard

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.

Exceptional Print quality

Exceptional Print quality

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.

Color LCD screen and simple UI

Color LCD screen and simple UI

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.

Quick-Swap Nozzles

Quick-Swap Nozzles

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.

Support for a wide range of Materials

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.

Prusa Connect and Connectivity Options

Prusa Connect and Connectivity Options

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 1 GB for free) and then transfer it into the printer’s USB storage and start the print remotely. All communication is encrypted.

6 reasons to choose the MK4

1

Great User Support

We offer 24/7 tech support via live chat and email in seven languages. Our printers come with detailed instructions and guides for easy assembly and maintenance. You can also visit our knowledge base, community forum, Facebook groups and official Blog, where we publish useful 3D printing tips and tricks, contests and more!

2

Fun to Assemble

The MK4 assembly kit is an excellent first step into the world of 3D printing. You will get to know your 3D printer inside out and find out how it works! The assembly is quite easy, requires no soldering, all cables are cut to length and ready to be plugged in. The assembly instructions are easy to follow and all of this makes the kit very friendly to younger builders, too!

Upgradability

One of the most popular features of the Original Prusa concept is upgradability. When you buy our 3D printer, you can upgrade it later to a newer version, so you don't need to buy a whole new model every two years like, for example, your phone or laptop. We also keep supporting our 3D printers with regular firmware updates that bring new features!
