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.
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.
Step 7: Make cookie dough (I used the Sugar Cookie recipe on p.612 of the Fannie Farmer Cookbook), heat the oven, and stamp out the cookies.
Step 8: Eat and be happy.
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.
