Convert SVG to STL

An SVG is flat. Making it printable means extruding the outline to a chosen thickness, which turns closed shapes into solids and any enclosed shapes inside them into holes.

Shapes must be closed

An open path has no inside, so there is nothing to make solid. If your design is drawn as strokes rather than outlines, convert stroke to path in your editor first — in Inkscape that is Path → Stroke to Path.

Holes are detected automatically

A shape enclosed by another becomes a hole rather than a separate solid, so a washer comes out as a washer rather than a disc. Nesting is worked out from containment, not from drawing order.

Choosing a thickness

1–2 mm suits keychains and tags. 3–5 mm gives wall art enough presence to not look flimsy. Thicker than about 10 mm is rarely useful from a 2D outline — at that point the shape wants real modelling.

Common questions

How do I turn an SVG into a 3D printable file?

Upload the SVG, choose a thickness, and convert to STL. The outline is extruded into a solid, with enclosed shapes becoming holes.

Why does it say my shapes are not closed?

An open path has no inside, so there is nothing to make solid. If the design is drawn as strokes rather than outlines, convert stroke to path in your editor first — Path then Stroke to Path in Inkscape.

What thickness should I use?

One to two millimetres suits keychains and tags. Three to five gives wall art enough presence. Much thicker than ten rarely helps, because at that point the shape wants real modelling.

Something wrong? Tell me

If a file will not convert, or the result looks wrong, I would rather hear about it. Include the format and roughly what you were doing — that is usually enough to reproduce it.

This form is the only thing on this site that contacts a server. It sends what you type above, plus your browser version and which page you were on — those two make bugs far easier to reproduce. Your files are never included and never leave your device. Please do not paste anything confidential.
