Color Mixing with DUAL PRO Extruder

In this tutorial you will learn, how to use the color mixing capabilities of DUAL PRO extruder, to create multicolor prints.

Before you begin, connect the DUAL PRO toolhead to the printer and calibrate the nozzle height.


Feed the extruder with desired materials (PLA and ABS are recommended for this). Also, make sure that you have the latest version of Voxelizer software by clicking "check for updates" in the "help" menu.


Let’s begin!

First of all, import the desired model into the Voxelizer (we would use the Proud Wolf from Designfutures), resize it if you want, multiply and orient on the table as you wish

Click "VOXELIZE" and wait for the software to finish the process.

Now, click on the toolbars menu and choose materials - Materials toolbar will appear. 

Then click Add and change the name and parameters of the newly added "extruder" to those, shown in the picture.


A few words of explanation of the newly added material functions:

  1. Name - name of the material.
  2. Color - display color of the voxel object.
  3. Type - type of mixing which would be made:
  • Simple - no mixing, simple color, which can be fed either from extruder left or right.
  • Complex - the model, which would be printed in this color would be a mix of colors in specific proportions (in the picture it’s evenly distributed).
  • Gradient - the color of the model, would be changing gradually from bottom to top, and you can choose the starting and ending extruder share. For example, if we set starting E1 to 100%, starting E2 to 0%, ending E1 to 0% and ending E2 to 100%, we will get a model with the bottom in full E1 color, top in full E2 color, and a mix in between.

Now we need to assign the materials to the models on the table. To do that, simply right click on the model, click "Set extruder" and choose one of the materials from the list.


Now you can change the settings of the print (outlines, infill, etc.), generate the gcode file and send it to your printer to start printing!




  1. Please make sure that the filaments you want to mix are of the same printing temperature (PLA+PLA, ABS+ABS, etc.).
  2. Not every filament mixes very well. Sometimes you can see the “toothpaste” effect on surfaces of your print (one side is more of color A while the other side is more of color B).
  3. You don’t have to restrain to 3 colors. You can add them as much as you want, with different proportions.
  4. If the filaments are not mixing properly, try to lower the printing speed, to give the materials time to mix.
  5. Adjust the “head change artifact” taking into account the coloration of used filaments (for example, black filaments colorizes second material a lot so it needs a lot of artifact generated).
  6. Printing with “gradient” material doesn’t require head change artifact, since the mixing is gradual.
  7. This tutorial only includes mixing two filaments.
