Innovation & Technology of Prusa MK4
Mechanical Innovations
- Frame Design: The Prusa MK4 features a new aluminum composite injection-molded frame, replacing the sheet metal frame of the MK3. This change provides greater rigidity, which is crucial for maintaining accuracy at high printing speeds. The frame is thicker, adding stability needed for the increased acceleration of the new machine.
- Extruder System: The Prusa MK4 introduces the “Nextruder,” a high-speed extruder based on the design first seen on the Prusa XL. This extruder uses a dual-gear system to control filament flow, offering greater control, especially with flexible filaments like TPU. The Nextruder also features quick-swap nozzles, allowing for easy changes between different nozzle sizes without tools. The planetary-geared Nextruder has a larger surface area touching the filament, enabling better control over filament movement.
- Bed Levelling and Calibration: The MK4 includes a Load Cell sensor for fully automatic first-layer calibration. This sensor allows for precise adjustment of the first layer height, even when using different nozzles, eliminating the need for manual Z-axis adjustment. The auto-bed leveling system is one of the key features that set the MK4 apart from its predecessor.
Print Quality Enhancements
- Printing Speed: The MK4 is designed for high-speed printing, with a maximum print speed of 600mm per second. The new extruder and frame design contribute to this increased speed while maintaining high print quality.
