SVG Paths for 3D Printing
An SVG's 2D vector outline can serve as the basis for a 3D printed object through an extrusion workflow in CAD software.

Extruding a Flat SVG Outline into a 3D Shape
Many CAD and 3D modeling tools can import an SVG file's 2D outline and extrude it, meaning the flat shape gets pushed or pulled along a third axis to create a solid 3D form, turning a simple flat vector logo or shape into a printable object with real depth and volume.

Preparing an SVG for Clean Extrusion
An SVG intended for extrusion into a 3D print needs fully closed, non-self-intersecting paths, since an open or self-crossing path can produce unpredictable or invalid 3D geometry once a CAD tool attempts to build a solid form from it, making path cleanup an important preparation step.

- Path cleanup is an important preparation step before attempting extrusion
Frequently Asked Questions
Can any SVG file be extruded into a 3D printable shape?
Not reliably — the SVG's paths need to be fully closed and free of self-intersections for a CAD tool to build valid solid geometry during the extrusion process.
What CAD tools support importing and extruding SVG files?
Several CAD and 3D modeling tools, including Fusion 360 and various open-source options, support importing an SVG's paths for extrusion into a 3D solid.
