How to make a custom 3D-printed stamp
- Choose Stamp + handle (or Raised relief / Engraved for a plate).
- Type initials, a name or a short word, or upload a logo. Bold shapes give the cleanest print.
- Set the size. Keep at least 2 mm of raised artwork on a stamp so the base stays out of the ink.
- Download the STL. The stamp and its handle come in one file, laid out side by side. Print both flat as downloaded, then push the handle's peg into the socket.
Recommended print settings
| Setting | Value |
|---|---|
| Material | TPU for ink on paper · PLA or PETG for clay, leather, wax and plates |
| Layer height | 0.12–0.16 mm for fine artwork, 0.2 mm otherwise |
| Walls | 3–4 (solid artwork) |
| Infill | 20% (100% for TPU stamps) |
| Orientation | As downloaded: stamp face up, handle knob down. No supports. |
| Two colours (relief) | Filament change at the height shown under the preview, or the 2-colour ZIP |
Frequently asked questions
Will my stamp print the right way round?
Yes. In stamp mode the artwork is mirrored on the stamp face, so the print on paper, clay or leather reads correctly. The preview shows the face, so text looks backwards there – that is correct. Relief and engraved plates are not mirrored; they read correctly on the object itself.
How does the handle attach?
The handle prints separately, knob down, beside the stamp, and has a hexagonal peg that pushes into a socket in the back of the stamp. The hexagon stops it turning. It is a snug fit; add a drop of glue if it is loose. The small notch in the stamp's edge marks the top, so you can line up the print.
Which material stamps best?
For ink on paper, TPU (flexible filament) gives the most even print because it presses flat against the paper. PLA and PETG stamps work well on clay, polymer clay, leather, soap, fondant and wax, and fine for ink on a soft surface such as a folded towel under the paper. Sand the face lightly with fine sandpaper for a crisper ink print.
What is the difference between the three modes?
Stamp: raised, mirrored artwork with a handle, for printing onto something. Raised relief: raised artwork that reads correctly, for plaques, panels and decorations; it can be printed in two colours. Engraved: the artwork is cut into the face, like an engraved plate.
Can I use it for cookies or food?
Standard 3D prints have small gaps between layers that trap food and are hard to clean, so use food-safe filament, keep contact short and wash well, or use the stamp to press a design into a food-safe clay or silicone mould instead.
What image works best?
A bold, high-contrast silhouette or logo. Thin lines under about 0.8 mm and fine photographic detail disappear or break off at stamp sizes. Use the Threshold slider to decide what counts as ink.
