A custom logo stamp from an online engraver costs $30–80 and takes 1–2 weeks to ship. A 3D printed logo stamp costs a dollar or less in TPU filament, takes two hours to print, and you can refine the design as many times as you want. For Etsy sellers, small businesses, and independent makers, it's the most practical way to brand packaging, notecards, and products.
Stamp3D accepts PNG, JPG, and SVG logo files and converts them directly to a 3D printable STL. SVG gives the best results — it processes as pure vector paths, so curves are smooth at any size. PNG and JPG also work well with high-contrast source images.
No account needed. Upload a PNG, JPG, or SVG — download a print-ready rubber stamp STL in seconds.
Open Stamp3D — It's FreeNot every logo translates well to a rubber stamp. The physical constraints of a stamp — minimum stroke width, lack of color, binary ink transfer — filter out certain design elements. Here's what works and what doesn't:
| Logo element | Works for stamping? | Notes |
|---|---|---|
| High-contrast black/white | Yes — ideal | No conversion needed |
| Bold, thick strokes | Yes | 2mm+ for FDM, 1mm+ for resin |
| Simple geometric shapes | Yes | Circle, square, triangle — all stamp cleanly |
| Clean wordmark text | Yes | Use bold/medium weight fonts |
| Gradients or shading | No | Stamp3D converts to B&W — gradients become blobs |
| Thin hairline strokes | No (FDM) / Maybe (resin) | Under 0.8mm disappears on FDM |
| Photographic detail | No | Too much information — simplify first |
| Multiple colors | No | Stamps are single-color by nature |
If your logo has gradients or thin strokes, simplify it before uploading. Create a black-and-white version in Illustrator, Inkscape, or Canva — flatten everything to solid fills with no gradients, and increase stroke weights to at least 2mm at the stamp size you plan to use.
SVG is strongly preferred. Stamp3D processes SVG files as mathematical vector paths — curves are perfectly smooth at any stamp size, and there are no pixel-related artifacts. If your logo exists as an SVG (from your designer, from Canva, or exported from Illustrator), use it.
PNG works well with high-resolution, high-contrast source images. Use at least 300dpi at the intended stamp size. Stamp3D applies a threshold conversion to make the image black-and-white — you can adjust this threshold in the tool to recover detail or clean up noise. A clean black logo on white background at 300dpi produces good results.
JPG works but introduces compression artifacts at edges. Use PNG over JPG when possible. If you only have JPG, use a high-quality export (90%+ quality) and expect to adjust the threshold slider in Stamp3D to get clean edges.
Size depends on where you're stamping — the stamp needs to fit the surface without being cramped or lost.
| Use case | Recommended size | Shape |
|---|---|---|
| Business card logo stamp | 30–40mm wide | Round or rectangle to match logo |
| Thank-you notecard | 40–55mm wide | Any shape |
| Kraft mailer bag / envelope | 50–65mm wide | Rectangle or logo-shaped |
| Tissue paper / packaging wrap | 50–80mm wide | Round or oval — easier to stamp repeatedly |
| Wooden box / crate branding | 70–100mm wide | Rectangle — scales well at large sizes |
When in doubt, go slightly larger rather than smaller. Logo detail that looks fine at 50mm can become illegible at 30mm on FDM. Test the smallest version on scrap paper before printing a final size.
Logo stamps live or die on fine detail — dry filament and a good ink pad matter more here than on any other stamp type.
