The MK4S to Prusa CORE One Conversion Kit transforms your Original Prusa MK4S into a fully enclosed, CoreXY-based professional 3D printer—unlocking greater speed, precision, and material compatibility. With enhanced thermal stability, a larger build volume of 250 × 220 × 270 mm, and an actively heated chamber up to 55 °C, this upgrade is designed for users who need to print advanced materials like Nylon, PCCF, and PEI (Ultem).
The kit reuses key components from your MK4S—such as the Nextruder, heated bed, and electronics—while introducing an entirely new motion system, enclosure panels, ventilation controls, and automatic temperature regulation. It also dramatically reduces the printer’s footprint by up to 50% compared to using a standalone enclosure. Ideal for engineers, prototypers, and advanced hobbyists, this conversion enables industrial-grade performance without the cost of a brand-new machine.
Key Features:
• Enhanced Performance: Upgrades the MK4S to a fully enclosed CoreXY system, improving print speed and precision.
• Larger Build Volume: Increases the build volume to accommodate larger models.
• Advanced Material Compatibility: Supports high-temperature materials like PCCF and Nylon without warping.
• Space Efficiency: Reduces the printer's footprint by 50% compared to the MK4S in an enclosure.
• Active Temperature Control: Maintains optimal chamber temperatures for consistent print quality.
• Automatic Ventilation: Ensures proper airflow and temperature regulation within the enclosure.
