3D printed Christmas cookies

3d-printing-christmas-cookies

Here is yet another way to get into the holiday spirit at your local Hackerspace (or at home if you’re happen to have your own 3D printer). [Ralph Holleis] wrote in to show off his 3D printed Christmas cookies. The majority of the info on this project comes from the video embedded after the break. The extruder head he’s using includes a syringe which is filled with what we assume is Spritz Cookie dough. It is squeezed out in a pattern before heading to the oven for baking.

[Ralph] mentioned that he’s using UNFOLD Pastruder as the print head. We looked and couldn’t find that exact design, but it seems like it might be related to this Claystruder head designed by a user named [Unfold]. If you have the exact link to the extruder design seen above please let us know in the comments section.

If you don’t already have this type of head it’s just a matter of printing the mounting brackets and buying a syringe to match. But you’ll also need compressed air and a valve to regulate the flow of dough. It might be easier just to print your own cookie cutters. This is a great project for people who don’t have access to a laser cutter for gingerbread¬†house work.

Potentially explosive spritz cookies

Do you recognize the shapes of these spritz cookies? Theoretical physicists and nuclear engineers might. They are representative of a hydrogen atom in several different states. Oh, and they’re delicious. [Windell] over at Evil Mad Scientist Labs cut his own spritz cookie discs in order to bake the hydrogen look-a-likes.

To bring you up to speed: spritz cookies are not rolled out and cut with a cookie cutter Рalthough you could print your own cutters in these shapes if you wanted to. Instead, a cookie press is used to squeeze out dough onto a baking sheet. The press looks like a very wide syringe. The dry dough is packed into a cylinder, and a ratcheting ram presses it toward the business end. A disc with wisely placed slits lets the dough squeeze out into the final shape.

We made some shamrocks for St. Patrick’s Day, but now we’re wondering if we can make our own Hackaday logo cookies. [Windell] grabbed some melamine dinner plates to use as raw material for his custom discs (remember to use food safe material). He then designed the cutouts in Inkscape and headed over to the laser cutter to fabricate the disc. We don’t have a laser cutter but we’d bet you can do a similar, but slower, job with a drill and a lot of filing/sanding.
