Free SVG to 3D Model Converter
Extrude any black SVG into a printable 3MF. Preview it in 3D, toggle a two-colour backing plate and a keychain ring, and open the file straight in your slicer. Free, no account, and your file never leaves your browser.
How it works
Drop any SVG with black filled shapes, or load the bundled example to see a result instantly.
Spin the live preview, set the extrude depth, and toggle the backing plate or keychain ring.
Open it in your slicer with the design and backing already assigned to two filaments.
Turn laser files into 3D prints
Laser cut files, stencils, and silhouettes are already perfect 3D printing material. Their black filled shapes describe exactly what should become solid plastic. This converter extrudes those shapes into a real 3D body, so the same design you would cut from plywood becomes a keychain, a sign, a magnet, or a piece of wall art on any 3D printer.
The optional backing turns a fragile cut-out into a sturdy two-colour plaque. The backing plate is written into the 3MF as a separate material, so slicers such as Bambu Studio, OrcaSlicer, and PrusaSlicer open the file with the design and the backing already mapped to two filaments. Add the keychain ring and the printed piece is ready for a split ring straight off the bed.
Everything happens locally. The SVG is parsed, extruded, previewed, and packed into the 3MF on your own device, which makes the tool fast, free, and private. If you only have a photo or a PNG, run it through the free image to SVG converter first, then bring the cut SVG here.
Frequently asked questions
What SVGs work best?
SVGs with black filled shapes, like laser cut files, stencils, and silhouettes. The tool extrudes the filled black areas into a solid 3D body. Outline-only SVGs, where the shapes are thin strokes instead of fills, need a filled version first. Cut files from our free converter or editor work perfectly.
Is it really free and private?
Yes. The tool is free, works without an account, and runs entirely in your browser. Your SVG is never uploaded to a server. The 3D preview and the 3MF file are both built on your own device.
What is the two-colour backing?
An optional backing plate behind your design, stored as a separate material in the 3MF. When you open the file in your slicer, the backing and the design are already assigned to two different filaments, so you can print a two-colour piece without any manual painting. You can adjust the backing thickness and outline offset before downloading.
What slicers open the 3MF?
Bambu Studio, OrcaSlicer, PrusaSlicer, and any slicer that imports 3MF. Bambu Studio and OrcaSlicer also pick up the two-colour filament assignment automatically. Single-extruder printers can still print the file in one colour, or use a filament swap at the layer where the design starts.
How do I resize the model?
The model exports with its longest side at 250 mm so it always imports at a sensible physical size. Scale it up or down in your slicer with the normal scale tool. Uniform scaling keeps the design and backing in proportion.
Why 3MF and not STL?
3MF carries colour and material data along with the geometry, which is how the two-colour backing arrives in your slicer already assigned to two filaments. STL stores bare triangles only, so the colour information would be lost. Every modern slicer opens 3MF, and you can still export STL from the slicer afterwards if you need it.
