Main improvements

This list is of the improvements and special features compared to most RepRap 3D printers:

  • large format
  • expandability, allowing for the creation of larger or smaller printers


The Omega3D is currently in an "under-wraps" development stage and will be released when the development is complete.


Printed Parts

Frame type

The Frame of the Omega3D is constructed of lightweight, strong aluminum 20x20 extrusions.


- light and sturdy - modifiable


- slightly more complicated construction method


Stepper Motors

The Omega3D uses, including the extruder, 5 NEMA17 stepper motors. Two of these motors, the Z axis motors, are connected to the same stepper driver of the electronics. If using Wade's Extruder, its stepper motor needs a minimum holding torque of 40Ncm (0.4Nm). More information can be found on the Stepper Motor page.

Controller Electronics

About any RepRap controller works for the Omega3D. Required features: 4 stepper drivers, 1 thermistor input and 1 heater output for the extruder and optionally another thermistor/heater pair for the heated bed. Choosing the best one for your printer is mostly a matter of taste. For comparisons, see List of electronics, Comparison of Electronics and Alternative Electronics.


Extruder The Omega3D uses a bowden extruder, adding flexibility and speed to the extruder nozzle.

Heated Bed

Heated Bed The basic model of the Omega3D does not include a heated bed, thus making PLA a recommended filament.
