More info

This printer is based on a Prusa i3 frame and mechanics with a dual Ormerod 2 extruder. It features Z axis auto bed levelling. The Ormerod 2 bowden extruder is one of the most simple, fastest and steadiest extruder, taking 1.75mm filament, extruding 0.5mm with a recommended 0.24mm layer height. The maximum accuracy is 0.1mm. 

Replikeo developed this printer by merging the best components of the most famous and reliable printers on the market, Prusa i3 and Ormerod 2. The plastic parts holding the frame and axis are all ABS injected, so they won't break with time.

This kit contains all parts needed to build the dual extruder 3D printer and 1kg of PLA plastic filament.

Why a dual extruder 3D printer ?

  • Print support material in PVA or HIPS to get clean result after dissolving the support, even for complicated shapes
  • Different colors will give more life to your objects
  • Suiting better designers and artists who have to print complicated and smooth shapes

Strong points

  • Z axis auto bed levelling
  • No soldering, cutting or other assembly trouble
  • Ormerod 2 extruder is small-weight, fast and reliable
  • Bowden tube decreases the carriage weight for more accuracy
  • Plastic parts are reinforced
  • Fasteners are in stainless steel
  • Endstops are better located
  • Y-axis belt can be tighten easily
  • Print surface on carbon plate
  • Y-axis threaded rods are 10mm thick

This kit is complete and includes

  • 1x Set of black Moulded ABS plastic parts (extra parts for the dual extruder are 3D printed).
  • 1x Frame and carriage

Build instructions 


If any part is damaged on arrival, we will change it for you for free. Our plastic parts are now moulded, not printed anymore, it's now very strong, however we suggest that you print backup parts when your printer is running.
