Step 3: Create the Pattern & Export
Lastly, apply the Voronoi effect using the pattern tool in meshmixer. To access this tool, navigate to “Edit” on the left-hand tool bar. Next, select “Make Pattern”. You will then be presented with a dialog box containing the parameters for your pattern.
I used the “Dual Edges” setting in the first dropdown. This produces a more tubular look, but any of the patterns will work. I then changed the “Element Dimension” setting to achieve my desired spacing between the tubes. (Note: You want to use a small to medium size spacing if you wish to print it without support material.)
We will now export the model as a new STL. Navigate to “File>Export”, or simply click the “Export” button on the left-hand toolbar. Give it a name, and click “Export” in the dialog box.
Now you’re ready to import your new model into your favorite slicing software and print it.
