3D-printed rollers can be
custom generated starting from images, by using the software
provided below. These rollers can be used to imprint
your favorite frieze patterns and tessellations on to your
favorite cookies, ceramics, and other plastic materials.
Here are some sugar cookies made by this technique.
And here are some cocoa cookies:
More examples can be seen
below, along with the stl files to produce the
rollers. To make your own patterned cookies, just
print a custom roller on a nearby 3D-printer and roll the
roller over the dough before baking. More information
is given in the paper.

This is a joint project with Robert Hanson of Towson
University. For details see this draft paper:

The program to process an image
and create the stl files for your own rollers is here
. To run
it, you must have access to Mathematica.
Download the stl Files
If you have access to a 3D printer, you can replicate the
rollers illustrated here from these stl files. These
were all printed in ABS plastic on my Makerbot Replicator
I've also included the images used as input to the
software. There files are provided for non-commercial,
educational use only. See the paper above for image
