A friend of mine is a huge Dr. Who fan and asked me to make her a Seal of Rassilon cookie press. This 1.5 in press took about 6 minutes to cut and it is easily scale-able if you'd like it bigger. After I did a test run with these cookie presses, I realized that I wanted some cookie presses too! Files for the following shapes are attached: Seal of Rassilon (Dr. Who), Star Trek federation insignia, Hello Kitty, "Cookie", ?, and 2015.
In Illustrator I made two layers. The raster layer in black is the Symbol of Rassilon which will be engraved at least 1/8 inch, the red layer is a vector layer to cut through the acrylic. The attached shapes are slightly adjusted from the original and should work better.
Note: If you are designing these yourself, remember that these are stamps, so you need mirror images (object>transform>reflect>axis:vertical in Illustrator). Black is what gets cut, so if your image is white on black, you'll indent into the surface of the cookie. If your press is black on white, your image/text will be raised from the cookie.
Step 1: Set Up Your Laser Cutter
Bonus Step: Rummage through trash to find suitable material. The Fab Lab just had a major cleanout, so there was plenty of spare acrylic. Cookie presses are pretty small and fit easily onto scrap pieces.
Those settings are highly dependent on your laser cutter. I was using a Universal Systems 32"x18" laser cutter. You may or may not need multiple passes. You'll know that you've cut all the way through the material when is slightly drops down. You'll want it to engrave as deep as possible. I like for it to be engraved about 1/8 of an inch deep, but it doesn't need to be perfect.
Tip: I like to leave the backing on when I cut, that way the bottom of the acrylic doesn't burn from flash back.
Step 2: Clean Up!
Peel off acrylic backing and wash off dust with dish soap.
Step 3: Make Cookies!
These work awesome with sugar cookies:
