A 3D printed stamp is a custom rubber stamp made using a 3D printer instead of laser-cut rubber or photopolymer. Print it in flexible TPU filament (FDM) or flexible resin (resin printer), attach a handle, and it works with any standard ink pad. You can make any shape, size, or design — text, logos, borders, or artwork — and download a ready-to-print STL file for free using Stamp3D.
Type text or upload a logo. Choose rectangle, circle, or oval. Download a print-ready STL in seconds — no account, no software.
Open Stamp3D — Free3D printing is surprisingly versatile for stamps. Beyond basic rubber stamps, the same STL workflow works for wax seals, clay texture stamps, soap molds, and embossing tools. Here's a complete map of what's possible:
The single biggest factor in 3D printed stamp quality is your printer type. FDM and resin printers produce very different results, and the right choice depends on the detail level you need.
| Factor | FDM (TPU filament) | Resin (flexible blend) |
|---|---|---|
| Min. letter height | 4–6mm (0.4mm nozzle) 2–3mm (0.2mm nozzle) |
1.5–2mm |
| Logo detail | Good for bold designs | Excellent — fine lines preserved |
| Stamp feel | Flexible rubber (TPU 95A) | Slightly firmer rubber (80/20 blend) |
| Post-processing | Sand face with 400-grit | IPA wash + UV cure (5–10 min) |
| Surface quality | Layer lines visible; ironing helps | Naturally smooth from FEP film |
| Print time | ~30–60 min for a 50×25mm stamp | ~30–45 min (full plate at once) |
| Verdict | Best for large text, address stamps, bold logos | Best for fine detail, small text, intricate designs |
If you're choosing between them for a first stamp project: FDM with TPU is the lower barrier. It's forgiving, doesn't require handling hazardous chemistry, and produces great results for text stamps 5mm and larger. For a detailed logo or small personal stamp, resin is worth the extra steps.
All of these are TPU-family flexible filaments. The hardness rating (95A, 40D, etc.) refers to Shore hardness — lower = softer = better ink transfer, but harder to print.
| Material | Hardness | Print difficulty | Best for |
|---|---|---|---|
| TPU 95A — Polymaker, Overture | 95A | Easy | Starting point. Works on nearly every printer. The community standard. |
| Fiberflex 40D | 40D softer | Moderate | Better ink transfer, hides layer lines. Best FDM result in Prusa community testing. |
| VarioShore TPU | Variable | Moderate | At higher temps, becomes foamy — porous surface improves ink uptake and hides layer lines. |
| PLA | Rigid | Easy | Wax seals, clay stamps, soap stamps only. Too stiff for ink pad use. |
Use an 80/20 blend: 80% flexible resin + 20% standard resin. This is the community sweet spot — prints reliably, has real rubber flex, and doesn't require the extreme care of pure flexible resin. Pure flexible resin is notoriously hard to dial in (10+ failed prints is common before you get it right).
Good flexible resins: Siraya Tech Tenacious, Liqcreate Flexible-X, RESIONE F39, Prusament Resin Flex.
There's no universal answer, but here are the most common sizes by use case:
| Use case | Typical dimensions | Notes |
|---|---|---|
| Address stamp (3 lines) | 55–65mm × 25–30mm | Fits a standard envelope return address |
| Personal name stamp | 40–50mm × 18–22mm | 1–2 lines; keep text ≥5mm tall |
| Logo stamp (business) | 30–50mm wide, square or rect | Size depends on logo detail level |
| Craft packaging stamp | 40–60mm wide, circle or oval | "Handmade," "Thank You" — arc text looks great |
| Office stamp (APPROVED etc.) | 50mm × 20mm | Classic ratio; bold caps work well |
| Wax seal | 20–35mm circle | Deeper relief (2mm+); PLA or brass works |
| Clay texture stamp | Any | Flat tile designs; press firmly into clay |
The traditional workflow requires CAD software or OpenSCAD scripting. Stamp3D skips all of that — it runs in your browser and generates a watertight, print-ready STL with no software to install.

Open the Free Stamp GeneratorDesign your stamp in Stamp3D, download the STL, and send it to an online 3D printing service. Treatstock is a good option — it connects you to local print shops worldwide, and flexible resin stamps typically ship for $15–25 total including printing and shipping.
For the best quality when ordering online, choose flexible resin over FDM. Resin handles small text and logos much better, and the surface quality from a professional printer is noticeably cleaner than home FDM.
Yes. TPU 95A filament on a standard FDM printer produces flexible rubber-like stamps that work with any ink pad. Resin printers go further — handling text as small as 1.5mm with a naturally smooth stamping surface. Both approaches produce stamps that work immediately after a brief post-processing step (sanding for FDM, IPA wash + UV cure for resin).
TPU 95A is the community standard. It's flexible, holds ink evenly, and prints reliably on most FDM printers. Softer options — Fiberflex 40D, VarioShore TPU — produce better ink transfer and hide layer lines more effectively. PLA is too rigid for ink pad stamping, though it works for clay, soap, and wax seal stamps.
On a 0.4mm nozzle FDM printer, keep letter height at 5mm or above for reliable results. A 0.2mm nozzle roughly doubles achievable detail (2–3mm letters become crisp). Resin printers handle text as small as 1.5–2mm reliably, making them far better for fine logos and detailed designs.
No. Design your stamp in the browser with Stamp3D and download the STL. Without a printer, send it to Treatstock or a local makerspace to have it printed in flexible resin and shipped to you.
For most practical uses — addresses, logos, packaging, office stamps — yes. FDM stamps are fully functional with any ink pad. Resin stamps approach commercial quality. The main limitation is minimum text size: keep letters at 5mm+ for FDM, 2mm+ for resin. Commercial photopolymer stamps can go smaller, but the gap is only relevant for very fine detail work.
