  • This project upgrades Ultimaker 2+ to a reliable dual extrusion printer.
  • The approach is based on the great effort everyone put into Mark2 for Ultimaker 2 and Ultimaker 3. 
  • The print head holds two hot ends, which are originally to be installed on standard UM2 head for 1.75 filament. The right nozzle move up and down nozzle swapping. 
  • This compact dual print head can achieve single extrusion print area of 220x223x205, and dual extrusion print area of 202x223x200.







  • Lever lifting mechanism is inspired by Ultimaker 3.
  • The firmware is modified based on Mark2 version of Tinkergnome firmware by tinkergnome.
  • CURA profiles are modified based on the Mark2 profiles by tinkergnome and foehnsturm​​​​​​​. - Used Mark2Tweaks plugin for CURA by Krys Lawrence.
