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 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
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.

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
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.
