Seal your design files with an invisible ownership signature and register them, or verify anyone else's file. We never store your file.

Seal a file

Costs 3 credits. Paid plan required. We write an invisible signature into your model, register its shape, and hand the sealed file back.

These licence lines are plain-language templates, not legal advice. We store only the details above and a signature of the shape, never your file.

Verify a file

Free for anyone. Drop in a file to see if it's registered, and to whom.

Provenance and a deterrent, not DRM. It proves who registered a file and when; it is not a ruling on authorship.

Issue a copy for a recipient

Send a uniquely sealed copy of a design you already registered to one place or person, with its own licence. If that copy leaks, Verify names the recipient. Costs 1 credit.

Signet: seal and verify ownership of your 3D files

Signet stamps an invisible ownership signature into your 3D file and registers it, so you can prove a design is yours and check whether someone else’s file is registered.

How it works

  1. Upload your STL or 3MF and add your name or company, a licence, and a few details.
  2. We write an invisible signature into the file and register its shape, then hand the sealed file back.
  3. Anyone can drop a file into Verify to see if it is registered, and to whom, for free.

What it does that the others do not

Survives re-export

A shape signature identifies your design even after it is converted or re-exported, when a plain watermark would be gone.

We never keep your file

Processed in memory and discarded. Only your details and the shape signature are stored.

Public verification

A free, public check anyone can run, so a marketplace or buyer can confirm provenance.

What people make with it

Selling on marketplaces

Seal a file before you upload it to MakerWorld, Etsy, Cults3D or Printables, so you can prove it is yours later.

Sending files to clients

Register a design before handing it over, with the licence terms recorded alongside it.

Settling a dispute

Point a marketplace or buyer at the public verify page to show who registered the file and when.

Recommended print settings

  • Works on binary and ASCII STL and on 3MF files.
  • The signature is far finer than any nozzle or slicer step, so it never changes how the model prints.
  • The seal survives an honest copy of the sealed file; the shape signature survives re-export and format conversion.

Questions

Does it change how my model looks or prints?

No. The signature is far finer than any nozzle or slicer step, so nothing about the shape or the print changes.

Do you keep my file?

Never. Your file is processed in memory and discarded. We store only the details you type and a signature of the shape, never the model itself.

Is this unbreakable?

No, and no watermark is. It is provenance and a strong deterrent: it proves who registered a file and when, and the shape signature still identifies your design even if someone re-exports it. It is not a ruling on authorship.

What does it cost?

Sealing a file costs a few credits on a paid plan. Verifying any file is free and public, so anyone can check a file against the registry.

Also called

People look for this as a 3D model watermark, STL copyright protection, a way to prove ownership of a 3D print file, or a design provenance and verification tool.
