PNG, JPG, or SVG. Solid silhouettes work best.
Upload a picture or an SVG and get a print-ready cutter: a sharp cutting edge that follows your outline, a wider reinforcing rib above it so the walls do not flex, and a flat top you can press on with your palm. It works for cookie dough, fondant, polymer clay, soap and play dough.
The outline comes from your image, so anything with a clear silhouette works: a logo, a pet's profile, a name written in a heavy font, a child's drawing.
The tracer looks for one closed silhouette, so contrast is everything.
| Works well | Causes trouble |
|---|---|
| Solid black shape on white | Photographs with a busy background |
| SVG with real vector paths | Very low-resolution images, which trace jagged |
| Bold, heavy fonts | Thin script fonts, which trace into fragile strokes |
| One connected shape | Many separate pieces, which become many cutters |
If your line drawing shatters into lots of tiny cutters, the strokes are too thin for the trace resolution. Thicken the lines in any image editor, or upload it larger, and re-trace.
| Setting | Use | Why |
|---|---|---|
| Material | PLA or PETG | Both are rigid enough. PETG survives dishwasher heat better |
| Layer height | 0.16 to 0.2 mm | Fine enough for a clean edge without a long print |
| Walls | 2 to 3 perimeters | The cutting edge is mostly perimeter, so this is what makes it strong |
| Infill | 10 to 15% | The rib does the stiffening; more infill just adds time |
| Supports | None | A cutter prints flat on its top face with no overhangs |
| Orientation | Cutting edge upward | Puts the flat top on the bed for a clean first layer |
A printed cutter touches food briefly and then gets washed, which is a much lower risk than a mold that food sets inside. Even so, printed plastic has layer lines that trap residue. Hand wash in warm water, do not put it in the dishwasher unless it is PETG, and treat a cutter as a tool with a finite life rather than a permanent kitchen item. The full picture is in are 3D printed molds food safe.
Usually the edge is too blunt or the dough is too soft. Chill the dough first, and press straight down without twisting. A sharper edge cuts better but chips more easily, so there is a genuine trade-off.
Dip the cutter in flour between cuts. If it still sticks, the walls are catching on layer lines, so sand the inside face lightly or print at a finer layer height.
Anything narrower than about 1 mm at print scale is fragile. Scale the whole cutter up, thicken the shape in your source image, or accept losing the finest detail. A cutter cannot hold detail a nozzle cannot draw.
Expected. A cutter is an outline, so an enclosed island (the middle of a letter O, an eye) has nothing holding it in place. Use a stamp instead if you need interior detail, or accept the silhouette.
