The upgrade kit is designed for the Original Prusa MK4 3D printer with a newer version of the xLCD display.
Product description: MK4S upgrade kit - for Original Prusa MK4 3D printer - for self-assembly - new xLCD version
The MK4S upgrade is a significant upgrade over the Original Prusa MK4 printer . It introduces a modern, high-performance 360° cooling system that precisely directs airflow onto the print, allowing for extreme overhangs of up to 75° with minimal support. The high-flow nozzle increases filament flow and speeds up printing without the need for specialized materials. The MK4S printer utilizes Input Shaper and Pressure Advance technologies, reducing vibrations and improving filament flow, ensuring quiet and fast operation.
