Personalized 3D Printed Cookie Cutters

I saw this great item from CopyPastry for sale on Etsy and thought — hey, why not see if I can make something similar?

So, following the good advice of a few online how-to’s (e.g., convert photo to line drawing) I found my way through to a printable model that resulted in a unique birthday gift for a good friend.

Here’s how:

Step 1: Select a high-resolution photo of your subject’s face. I used one in jpg format.

Step 2: Desaturate the image and then use the Difference of Gaussian filter to find the edges and create the line drawing. Save as a jpg.

Step 3: Import the line drawing into Inkscape and use the Trace Bitmap to create an svg file.

Step 4: Import the svg file into Tinkercad and create the 3D

file. Then export as an stl file.

Step 5: Import the stl file into Cura and configure the print settings.

Step 6: 3D print the file.

A few things I learned:

  • Creating contiguous lines in the line drawing makes it easier to print a template that will easily cut out a shape; too many points make it a bit more difficult to print the template.
  • Check to make sure you have some distance between the walls of the shape and the details of the face. You may have to experiment and print a few different models.
  • Fine points make it harder to remove the dough from the template once you’ve cut it out.
  • It’s hard to wash 3D printed templates; the layers make it difficult to prevent build-up in the crevasses.
