Dual Color 3D Printing



Introduction: Dual Color 3D Printing

About: I am a novice cad designer and I own a Prusa i3 MK3. I design things in tinkercad and fusion 360. I also do some coding and electronics. Working on a few other projects probably will be up on instructables eve…

Some 3d printers are capable of printing in dual color. However it works a little differently.

Step 1: Things to Avoid

  • Overlapping colors confuses slicer and sometimes crazy stuff happens
  • If color is not properly supported it will droop as shown in picture

Please let me know about anything else I should add

Step 2: Check Your Slicer Capabilities

Make sure your slicer can read dual color obj and stls. In some software you need to split up the file into multiple parts.

If not there is a work around.


This is probably better for projects with a large file size as well

  • create a square of 4 .01-.02 mm circles around the object and save colors separately both with all 4 circles
  • Load into slicer and align

Step 3: Slicing

In some slicers it is very simple like cube print in others it is a bit harder


I would recommend using the alternative method to create your file. Instructions are for alternative

  • Bring files in
  • Center them on bed
  • Go to "Tools"
  • Then "Dual Extrusion Wizard"
  • Pick where colors go
  • Hit prepare to print
  • Make sure to hit "Select All"
  • Hit "ok"
  • Save

Cube print

Only for cube 3 Just grab and drop colors

Possibly adding cura not sure how well it will work have not tried it yet

Step 4: Printing

Justs send file to printer like normal.

Prints will take much much longer since the printer needs to swap colors several times and that takes around 30 seconds each time.
