LDO Orbiter V1.5 Dual Drive Direct Extruder


In stock, ready to ship.

The LDO Orbiter V1.5 Dual Drive Direct Extruder as seen on Thingiverse. Designed by Dr. Lorincz Rober in cooperation with LDO. 


  • Compatible with flexible filament
  • Reduced stringing compared with bowden extruder
  • LDO HT motor, which is rated for 180℃ and allows for faster acceleration and direction change
  • Only ~150g weight, resulting in increased print speeds without sacrificing quality.
  • Glass fiber reinforced nylon injection molding parts instead of printed parts for housing, more robust/durable
  • DuPont Delrin injection molded gear, longer lifespan
  • Hardened steel dual drive gear provides bigger feeding force for filament
  • Recommend stepper current 0.35A RMS, don't exceed 0.5A

 What's changed from v1

  • DuPont Delrin molded planetary gears
  • Glass fiber reinforced Nylon housing and latch
  • Filament guide part of the extruder housing
  • PTFE tube connector on top
  • New stepper motor LDO-36STH20-1004AHG - 20mm long with more torque
  • Some internal bearings dimensions has been changed to simplify assembly and improve the molding process quality
