3d Printed Christmas Cookies
via hackaday
Instead of using plastics, the Unfold design studio uses cookie dough to 3d print their holiday cookies. The 3d printer prints the cookie dough directly onto wax paper, which they cook until delicious. They seem to be using this paste extruder head on a RepRap printer. For more details on 3d printing in doughs and clays, check out the Unfold blog.
