Free Wax Seal Stamp Generator

A 3D printed wax seal stamp costs almost nothing to make and produces impressions as sharp as commercial brass seals — if you print it right. Here's how.

Custom wax seal stamps typically cost $30–80 from engravers, with 2–3 week lead times. A 3D printed wax seal stamp costs $0.50–2 in resin or filament, prints in under two hours, and you can iterate the design as many times as you want at no additional cost. Design one in Stamp3D's free 3D stamp maker — no software or account needed.

The quality difference between a 3D printed and commercially made wax seal comes down almost entirely to printer type. FDM produces decent results for bold monograms and simple designs; resin produces impressions that are genuinely difficult to distinguish from professionally engraved brass seals.

How to Set Up a Wax Seal Stamp in Stamp3D

  1. Open Stamp3D and choose Circle shape. Set diameter to 25mm (standard wax seal size) or 30mm for a larger seal.
  2. Type your monogram, initials, or text. For a classic look, use a single letter or two initials. Stamp3D's arc text feature lets you curve text around the border of the circle.
  3. Keep Mirror text ON. Unlike clay stamps, wax seal stamps work like rubber stamps — the wax picks up a mirrored impression that reads correctly when you lift the seal.
  4. Increase relief height to 2.5–3mm. Deeper relief gives crisper wax impressions and makes lifting the stamp cleaner.
  5. Download Stamp STL only — you don't need Stamp3D's handle for wax seals. Use a wax seal handle (wooden dowel, brass handle, or a spare pen cap) instead.
Mirror stays ON for wax seals. The wax receives a mirrored impression of the stamp face, which reads correctly when you look at the cooled seal. If you turn mirror off, your text will appear backwards in the wax.

Standard Wax Seal Size

Most commercially available wax seal kits use a 25mm (1 inch) seal diameter. This fits standard wax beads, wax sticks, and most wax seal spoons. It's also proportioned correctly for a wax dot on an A2 envelope.

DiameterBest forWax amount
20mmSmall seals, mini envelopes, gift tags1 small wax bead
25mmStandard — works with all wax seal kits1–2 wax beads
30mmDetailed designs, wedding invitations2–3 wax beads
40mmLarge statement seals, packaging3–4 wax beads

If you're new to wax sealing, start with 25mm. It's the most forgiving size for beginners — enough surface area for a clear impression without requiring perfect wax amount control.

Resin vs FDM for Wax Seal Stamps

This is where printer type matters most. Hot wax fills in every surface imperfection of the stamp — layer lines included. FDM layer lines at 0.1mm are subtle but visible in the final wax impression. Resin (MSLA/SLA) produces a naturally smooth face that leaves no layer artifacts in the wax at all.

PrinterMaterialResult qualityBest for
Resin (MSLA)Standard resinExcellent — smooth, sharpWeddings, gifts, fine monograms
FDMPLA or TPUGood — slight textureCasual sealing, bold designs, prototyping

For wax seals that need to look professional — wedding invitations, client gifts, correspondence — print in standard resin. For everyday journaling seals or to test a design before committing to resin, FDM in PLA works fine.

Use standard (rigid) resin for wax seal stamps, not flexible resin. Wax seals need a firm, non-flexing stamp face to transfer sharp detail into the wax. Flexible resin can deform under stamping pressure.

Sand the stamp face lightly with 400-grit wet sandpaper after FDM printing to reduce layer line visibility in the wax. Resin stamps don't need sanding — the FEP film face is already smooth.

How to Use Your 3D Printed Wax Seal

  1. Attach a handle. The stamp face needs something to hold while pressing into hot wax. A wooden dowel (10–12mm diameter) glued to the back with epoxy works well. A spare metal pen cap also works — press the stamp back into the open end. Some makers hot-glue the stamp to a wine cork.
  2. Chill the stamp. Set the stamp face-down on an ice pack for 60 seconds before use. A cold stamp releases from the wax cleanly. A warm stamp sticks and pulls the wax apart when you lift.
  3. Melt the wax. Use a wax melting spoon or glue-gun-style wax stick applicator. Pour a small amount onto your surface — use more wax than you think you need.
  4. Let it set for 5–10 seconds before stamping. Wax that is too liquid spreads under the stamp. Wait for the edges to start setting.
  5. Press straight down, hold for 10 seconds, lift straight up. Don't rock or twist. Even pressure gives the cleanest impressions.

Wax Seal Generator FAQ

Is there a free wax seal generator?

Yes — Stamp3D's wax seal generator is completely free, with no signup and no account. Choose Circle shape, type your initials or upload a logo, and download a print-ready STL in seconds. Everything runs in your browser; nothing is uploaded unless you choose to share it.

Can you 3D print a wax seal stamp?

Yes. A 3D printed wax seal stamp works exactly like a traditional engraved brass seal. Resin (MSLA/SLA) gives the sharpest, smoothest impressions since it leaves no layer lines in the wax; FDM in PLA also works well for bold, simple designs. Print face-down for the smoothest stamp face, and keep Mirror text on.

What's the best way to 3D print wax seal stamps for weddings?

Print in standard rigid resin at 0.05mm layer height for the crispest detail — this is what gives wedding wax seals that professional, engraved look. Use a 25mm or 30mm diameter, keep Mirror text on, and chill the finished stamp on ice for 60 seconds before each use so it releases cleanly from the wax.

How is a 3D printed wax seal different from a rubber stamp?

A wax seal stamp presses into hot wax rather than ink, so it needs a rigid, non-flexing face — the opposite of a rubber/TPU ink stamp. Print wax seals in resin or rigid PLA, not flexible filament, and always keep Mirror text on so the design reads correctly once the wax cools.
