Fast and reliable printing. The MK4S is designed for speed without compromising quality. The new 360° cooling system allows for better overhangs and finer details, reducing the need for supports. The high-flow nozzle improves filament flow and shortens printing times while maintaining precision. Easy to use, ready to go right out of the box. Setting up the MK4S is straightforward. Simply unpack, plug in, perform a quick calibration, and start printing within 15 minutes. The user-friendly interface is perfect for beginners, while experienced users will appreciate the reliable performance. Compatible with a variety of materials. The MK4S handles a wide range of filaments, including PLA, PETG, ASA, carbon-filled materials, and flexible TPU. The direct drive extruder ensures smooth and hassle-free printing of flexible materials. Built to last. Like all Prusa printers, the MK4S is designed for continuous operation with minimal maintenance. The open design allows easy access to parts, and all components are built for durability. Offline and secure. You can operate the MK4S completely offline if needed. The Wi-Fi module can be removed for added security, and Prusa does not collect printing data without consent. Expandable with add-ons. The MK4S supports optional upgrades like the MMU3 for multi-material printing and an enclosure for improved temperature control when printing advanced materials. Whether you're printing for fun, work, or education, the MK4S delivers high-quality results with a simple and efficient workflow.
