Main Features

High-speed printing with ease


Effortless Highspeed Printing

Experience effortless high-speed printing with the MK4, incorporating our proprietary Input Shaper and Pressure Advance technologies in its firmware. By eliminating resonance and predicting filament flow, the MK4 significantly reduces print times by up to 70% compared to the MK3. Impressively, this remarkable speed is achieved while maintaining exceptional quietness during operation.


Perfect First Layer on a First Try


Impeccable First Layers Right Out of the Box

With the precision of the Loadcell sensor, the MK4 is capable of automatically creating a seamlessly smooth and even first layer without any user intervention. As the print begins, the printer probes the sheet using the nozzle in a grid formation, measures the distance, and calculates the necessary offsets. This leads to an impeccable first layer on all surfaces, eliminating the need for manual fine-tuning.


The Nextruder with Breakout Board


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.


32-bit xBuddy Mainboard


32-bit xBuddy Mainboard
