ReDuplicator i3 MK3x - Wanhao i3 Complete Aluminium Extrusion & Prusa Mk3 Overhaul

This project is a complete overhaul of the original Wanhao i3 with a few main objectives:
- Keep the core components of the printer while upgrading its structure.
- Create maximum rigidity through a sturdy 3030 Aluminium extrusion frame.
- Allow for future proofing and commonality of parts by basing all printed parts on the current Original Prusa MK3 files.
- Reduce the weight of the X and Y carriages where possible to improve print speed and quality.





The Wanhao i3 is a fabulous printer, but new generations of printers have begun pushing the boundaries. It has become apparent that in comparison, the Wanhao has a few deficiencies. Deficiencies which we will address in this project. The key improvements of this upgrade include:
- Much better rigidity through 3030 extrusions and metal brackets. Even with my or Azza’s excellent z braces the printer was still susceptible to slight wobble, especially under twisting forces (pull left tower and push right tower). When moving the printer it would require constant releveling due these small movements. Now i can barely get any movement using my full strength.
- Comfortably increase Z height to ~200mm
- Reduce noise. By not screwing the motors directly onto the metal frame, motor vibrations and noise is reduced significantly.
- Move towards more standard Prusa files for future upgradability,…
