The upgrade kit is designed for the Original Prusa MK4S 3D printer with the newer xLCD display.
Product description: CORE One upgrade kit - for Original Prusa MK4S 3D printer - for self-assembly - new xLCD version
The Prusa CORE One upgrade represents a significant improvement over the Original Prusa MK4S printer . The new design, based on a steel exoskeleton, provides exceptional stiffness and vibration resistance, while the 360° cooling system with an improved Nextruder guarantees perfect print cooling and improved detail reproduction. After the upgrade , the printer offers a larger build volume, an enclosed chamber with an operating temperature of up to 55°C, and the ability to work with more challenging filaments such as ASA , ABS , PC, PA (Nylon), and PCCF . The Prusa CORE One also offers higher print speeds of up to 170 mm/s while maintaining the highest surface quality. Thanks to full compatibility with the Prusa Connect platform and mobile app, you can manage your prints remotely, monitor progress, and use advanced control features.
