Want to turn any SVG file into a functional 3D stamp for polymer clay? Logos, initials, ornaments, or simple drawings can be quickly transformed into a clean and printable 3D stamp in Blender.
In this tutorial, I show a simple and repeatable workflow that lets you convert a flat SVG into a 3D stamp and download a FREE STL file, ready for 3D printing and polymer clay use.
Watch the tutorial – Easy 3D Stamp from Any SVG in Blender (FREE STL)
In this video, step by step, you’ll learn how to:
- import an SVG file into Blender,
- convert it into 3D geometry,
- set the correct thickness and height,
- create a simple and comfortable stamp,
- export a ready-to-print STL file.
Why SVG is perfect for 3D stamps
SVG files are vector graphics, which means they stay sharp at any scale. This makes them perfect for:
- clean and crisp stamped details,
- precise control over depth and thickness,
- logos and custom brand marks.
This approach is ideal for creating polymer clay stamps, custom tools, and decorative textures.
Process overview: from SVG to 3D stamp
1. Preparing the SVG file
Best results come from:
- simple shapes and bold lines,
- high-contrast designs,
- avoiding ultra-thin details.
2. Importing SVG into Blender
The SVG is imported as curves and then converted into a mesh that can be edited and extruded.
3. Extruding and adding thickness
The shape is extruded along the Z-axis to create depth that stamps clearly into clay.
4. Building the stamp body
You can add a base or handle to make the stamp easier and more comfortable to use.
5. Exporting STL for 3D printing
Once finished, export the model as an .STL file and prepare it for printing in your slicer.
Practical tips
- Stamp depth: 0.8–1.5 mm works best for polymer clay.
- Base thickness: at least 2–3 mm for strength.
- Material: PLA or PLA+ is more than enough.
- Test first: always test the stamp in clay before production.
This workflow lets you turn any SVG into a functional 3D stamp for polymer clay in just a few minutes. It’s a fast way to personalize your designs, build your own tools, and create textures that truly match your style.
