Watching my kids frosting cookies one day, I thought it would be fun to make a mold with their faces on it so that they can paint these cookies afterwards. So I set out to make a 3d printed cookie mold from their picture.
Step 1: Photoshop the Image
1. Basically I took the image of my little girl and I cropped it in photoshop.
2. Then I made it grayscale, and played around with the contrast and brightness.
3. Lastly, I "posterized" it into setting 2 so that the image is now black and white.
Step 2: Illustrator Outline
Then I took the image to illustrator and did a live trace. You need to play around with this, the setting depends on how detail you want.
Step 3: 3d Modeling
The last step you will need a little bit of knowledge in 3d Modeling software. I used Rhino, imported the illustrator file (I exported as dxf), offset, extrude and gave the piece a base.
Finally step is to export it into stl file and print from any 3d printer of your choice.
