Stamp3D

What is Stamp3D?

Stamp3D is a free browser tool that turns typed text or an uploaded logo into a 3D printable stamp. You type up to three lines of text or upload a PNG, JPG or SVG, pick a rectangle, circle or oval, set the size in millimeters or inches and download the stamp as an STL. The model is built on your own computer and no account is needed. Color images are turned into black and white with a threshold slider, while SVG logos keep their smooth vector edges.

Most settings help the stamp print and ink well. Round and oval stamps can have text running along the top and bottom arc, borders can be solid or dashed, and a logo stamp can sit on a base that follows the outline of the logo. Relief height has presets for water based, general, oil based and fabric ink, the STL is mirrored by default so prints read the right way, and there are separate modes for FDM and resin. For the handle you can download a separate grip STL to glue on or build a handle into the stamp as one print.

The domain was registered in May 2026, the privacy page was revised in July 2026 and the site says it is in active development. It comes with guides for clay, soap, wax seal, logo and address stamps. It suits crafters, small shops and anyone who wants a logo or return address stamp.
