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.

• The successor to the award-winning 3D printing workhorse Original Prusa MK3
• Effortlessly fast and silent 3D printing. 
• Fully automatic first layer calibration thanks to the Load Cell sensor
• Print right out of the box - no print sheets profiles, no tinkering, no Live Adjust Z!
• Nextruder – our new extruder with a custom breakout board and smart features
• Safety features like filament sensor and power panic that won't let you down
• Easy maintenance, quick-swap nozzles, and removable print sheets
• Support for a wide range of materials, incl. PLA, PETG, Flex, Nylon, ASA, PVA, PC, PP, composites and more
• Color LCD screen with simple-to-navigate UI and quick access to all important functions
• Ethernet and Wi-fi connection
• Made in the EU, hassle-free warranty, 24/7 live chat support
• Open-source

Significant Features:

1. 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. Support for high-speed printing is just around the corner via a firmware update.

2. 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.

3. 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.

4. 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.

5. 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.

6. 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.

7. 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.

8. 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!

9. 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.

10. 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 2 GB for free) and then transfer it into the printer’s USB storage and start the print remotely. All communication is encrypted. 

Technical Parameters:

* 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.

Basic package includes:

• Original Prusa MK4 Assembled 3D printer
• Double-sided Smooth PEI Print Sheet
• 1kg of Prusament PLA Galaxy Black
• 3D Printing Handbook
• USB drive with sample prints (G-codes)
• Toolset: Uni-wrench, 13-16 wrench, Philips screwdriver, Nose pliers, Allen and torx keys
• Alcohol-saturated wipes, acupuncture needle
• Spoolholder
• Spare parts package
• Prusa lubricant for bearings
• A pack of Haribo gummy bears
• Manufacturing protocol

Optional add-on available: Multi-color printing with MMU3

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.

The Enclosure is available with a range of useful add-ons, such as a filtration system, locking mechanism and more - check out our Enclosure listing here.
