🌟 Prusa MK4S – 3D Printer
The Prusa MK4S is an open-frame FDM 3D printer — available assembled, as a DIY kit, or assembled with an Enclosure. Built around the next-generation Nextruder extruder and the 32-bit xBuddy mainboard, it combines high printing speed, ease of maintenance, quiet operation, and compatibility with a wide range of materials. Over 90% of the parts have been renewed compared to the previous generation, with significant improvements in precision, connectivity, and print quality.
🔹 What distinguishes the Prusa MK4S?
- Nextruder extruder with 10:1 planetary gearbox — maximum temperature of 290°C, all-metal hotend, and CHT high-flow nozzle with 50 to 114% more flow than the previous standard nozzle.
- Automatic leveling with Loadcell sensor — perfect and uniform first layer without manual adjustments.
- Integrated Input Shaper and Pressure Advance — eliminates resonance and predicts filament flow for faster, more precise prints.
- 360° cooling with high-performance turbine — up to 75° overhangs without additional supports.
- Magnetic heated bed up to 120°C with removable PEI sheet — automatic mesh leveling across the entire print area.
- 0.9° stepper motors on X and E axes with Trinamic 2130 drivers — quiet operation and elimination of vertical artifacts.
- Hall filament sensor — automatic pause upon detecting end of spool.
- Power Panic system — full recovery after power failure.
- 3.5" graphical LCD screen with 65k colours, RGB status bar, and redesigned interface.
- USB, LAN, and Wi-Fi connectivity with integrated Prusa Connect — encrypted remote monitoring and control.
- Compatible with MMU3 (up to 5 filaments simultaneously) sold separately.
- Open source — firmware, software, and parts available for modification and customization.
