Key features

  • Enclosed chamber up to 55 °C for ASA, ABS, PC and PA (Nylon), while PLA and PETG print well even with the door closed
  • Updated Nextruder with 360° cooling, which prints 75° overhangs cleanly
  • CoreXY kinematics, high flow nozzle, Input Shaper and print profiles optimized for over 200 filaments
  • Fully automatic first layer calibration with the Loadcell sensor, and a pause with notification when filament runs out
  • Full steel exoskeleton, with every part removable using a screwdriver and no glued components
  • Up to 50% less space than the MK4S in an enclosed setup, with a 30% larger print volume
  • MMU3 ready, for printing with up to five filaments on a single nozzle
  • Open source software and firmware, with source code on GitHub

Accessories and upgrades

  • MMU3 multi-material unit for up to five filaments
  • Optional internal camera
  • Optional HEPA filtration adapter and advanced filter system
  • GPIO board and accelerometer support
