How to make a printable cookie cutter
Six steps from a description to a part off the print bed, and the measurements that actually matter.
-
Decide what you are making
A cutter is an open frame: it cuts a shape out of rolled dough. A stamp presses a design into the surface instead. Bakery Form can also build the two as one set, the stamp sitting inside its matching cutter.
- A cutter wants one clean silhouette. Interior holes are closed on purpose, so a shape defined by its gaps loses them.
- A stamp is where interior detail belongs: lettering, a logo, a face.
- Pick the mode before you generate — the same drawing is read differently by each.
-
Describe it in plain words
The generator draws a flat outline, so describe a shape rather than a scene. Name the subject, say which way it faces, and add one word about size. Short and concrete beats long and poetic.
- Good: “a sitting cat in silhouette, facing left, simple outline”.
- Avoid: “something creative” — there is no shape in that.
- A description past 500 characters is trimmed, so put what matters first.
-
Or start from a picture
Upload a photo and the subject is cut out from its background, then redrawn as a clean outline. A drawing that is already black on white is used as it is, without being redrawn.
- PNG, JPEG, AVIF and SVG are accepted; the background cutout works on PNG and JPEG.
- High contrast and one clear subject give the best cutout.
- An upload counts as one generation, exactly like a description.
-
The three measurements that matter
Size is the longest side of the finished piece, in millimetres. Blade is how deep the wall goes into the dough. Thickness is the wall itself — thin enough to cut, thick enough to survive the press of a hand.
- The starting values are 65 mm across, a 10 mm blade and a 0.8 mm wall: a good biscuit.
- Below about 0.4 mm² a detail is dropped rather than printed too fragile to survive.
- Changing any of these rebuilds the shape for free — you pay for the idea, not for the attempts.
-
Printing it
Every piece is built flat on its base, so it prints straight on the bed with nothing to support. The wall is aligned to a common nozzle, so it comes out as solid passes rather than a gap the slicer has to guess at.
- 0.8 mm is two passes of a 0.4 mm nozzle — the reason it is the default.
- No supports and no raft: the flat face is the first layer.
- The exported mesh is watertight, so a slicer needs no repair step.
-
After printing
Wash by hand in cool water and let the piece dry fully before putting it away. Printed plastic softens with heat, so keep it away from the oven, the dishwasher and hot water.
- Press straight down and lift straight up: a twist tears the dough.
- Lightly flour the edge if the dough is sticky.
- Check your own filament's guidance before using a print with food.
