Main Features

Effortless Setup and Operation

The MK4S is designed for simplicity with automatic calibration and one-click printing. Just unpack, plug in, and start printing once the automatic calibration is complete. Its open design, honed over a decade of innovation, ensures easy maintenance and upgrades. A comprehensive handbook guides you through every step.

Effortless Highspeed Printing

Experience up to twice the speed of the MK3S+ with the MK4S, one of the fastest desktop printers available. Featuring Input Shaper and Pressure Advance technologies, it minimizes resonances and optimizes filament flow. The result: faster prints with quieter operation, allowing you to work undisturbed. The MK4S can produce a SpeedBoatRace Benchy in 14 minutes and a “Bonkers” Benchy in just 8 minutes.

Introducing the Nextruder with Breakout Board

The extruder serves as the core of every 3D printer, and the Nextruder is truly exceptional. In contrast to most contemporary 3D printers where replacing extruder components can be complex, the Nextruder features a convenient connector break-out board. Components such as fans, heaters, thermistors, and more are directly connected to this board, simplifying the process of swapping parts down to just a minute. Experience hassle-free maintenance with the innovative Nextruder.

Advanced 360° Cooling System

The MK4S features a new 360° cooling system with a high-performance turbine and redesigned fan shroud. This system directs cold air precisely onto the print, outperforming traditional blanket fans. It maintains a quiet operation while handling extreme overhangs with ease, reducing the need for supports and saving material.

Superior Print Quality and Reliability

The MK4S 3D printer features a range of enhancements that elevate both its performance and reliability. It incorporates sturdier plastic parts and new precision 0.9° stepper motors (0.9°/step; low inductance) on the X and Y axes, effectively eliminating vertical fine artifacts and ensuring superior print quality. Thicker 10mm rods on the Z-axis contribute to its overall durability, making it well-suited for printing with challenging filaments like flexible materials. The MK4S achieves a perfect balance between speed and quality, thanks to its redesigned 360° cooling system and high-flow nozzle. This setup ensures precise cooling, handles extreme 75° overhangs with ease, and supports a wide range of materials, delivering exceptional dimensional accuracy for parts that fit perfectly.

Colour LCD Screen and Simple User Interface (UI)

The MK4's display enhances user experience with support for G-code thumbnails, QR codes, and other elements that simplify printer operation. The redesigned menus and customizable footer panel further contribute to a seamless user interface. An RGB status bar located directly beneath the LCD communicates the printer's current status, while a conveniently positioned USB-A port accommodates standard USB flash drives. Experience unparalleled ease of use with the feature-rich MK4 3D printer.

Quick-Swap Nozzles

With two quick-release thumbscrews on the side of the Nextruder's body, the MK4 3D printer makes nozzle swapping easier than ever before. Utilizing unique nozzles featuring an all-metal filament guide and eliminating the need for PTFE tubes, the MK4 enhances overall printer reliability, ensuring consistently high performance and user satisfaction.
