Wanhao Duplicator I3 V2 Mods

Submitted by on Jul 4, 2017

The Wanhao DuplicatorĀ I3 is an awesome machine that will print reliably once dialed in and with the help of a few modifications. Mine has printed the Mostly Printed CNC parts (120+ hours) with no issues, failed prints or restarts!

Here are the mods I have made:

  • Enclosure – I used 3/4″ plywood for the base and 1/4″ MDF for the enclosure. This addition allowed me to moved all the contents of the power supply and place it under under the printer. The power supply and control board are mounted to an MDF board which allows for easy access.
  • Octoprint – Controls the printer remotely and with a relay connected to the Pi, this allows me to remotely turn off the printer and light.
  • Y-axis plate – Thicker plate and added another bearing making it 4 instead of the original 3.
  • Wanhao I3 V2.1 upgrade kit.
  • LED Lights – Octoprint can turn these light on or off remotely.
  • PEI on the heatbed – Provides nice adhesion for PLA and ABS.
  • Heat bed insulation – I used material from a car windshield insulation from the the dollar store. This actually cut down the heating time by at least 30%.
