Original Prusa MK4 3D Printer Assembled by Prusa - ETL Certified

This Product is ETL certified and in compliance with Canada Electrical Authority. 

NOTE: Filaments Shown in the Photo is not included with the printer. 

The MK4 provides high-speed 3D printing with ease and is ever so reliable like all Original Prusa 3D printers. It has all the best features of the popular MK3 – an open-source 3D printing workhorse with easy maintenance and advanced safety features – and adds much more!

The MK4 will consistently deliver a perfect smooth first layer thanks to the Loadcell sensor (no manual adjustments needed). The next-gen extruder (Nextruder) and 32-bit connected platform provide many quality-of-life improvements like remote printing, quick-swap nozzles, and customizable UI with a one-click printing option.

Alternatively, you can try the full "Prusa Experience" with the printer kit, which you will assemble by yourself (it takes around 8 hours), and learn more about how the printer works.

Description 

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.

Features 

Main Features

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. Support for high-speed printing is just around the corner via a firmware update - read the blog post here.

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.

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

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.

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.

Slice with PrusaSlicer

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!
