Built for Logos, Keychains, and FDM-Ready Reliefs
Turn closed, filled vector art into a solid extruded mesh in your browser — then slice it in Bambu Studio, Cura, or PrusaSlicer.
Filled Vector Paths Become Solid 3D Reliefs
Closed filled shapes (logos, letters, silhouettes) are extruded into a solid mesh. Inner cutouts in letters like 'O', 'A', and 'P' are preserved. Stroke-only paths (fill=none) are skipped — convert those to fills in Inkscape or Illustrator first.
Inspect Dimensions Before You Slice
After upload, preview the mesh and check bounding box, triangle count, and watertight status. Extrusion depth is 10 mm; scale the model in your slicer if you need a thinner keychain or a taller badge.
Export STL or 3MF for Any Slicer
Download a single solid .stl or .3mf mesh and open it in Bambu Studio, OrcaSlicer, Cura, or PrusaSlicer. 3MF here is a compact mesh container, not a multi-color AMS project — paint colors in the slicer if you need them.
How to Convert SVG to STL for 3D Printing
Upload a filled vector file, preview the extruded mesh, then download .stl or .3mf for Bambu Studio, PrusaSlicer, or Cura.
Upload Your Vector File
Upload a .svg made of closed, filled shapes. Convert strokes to fills in your vector editor before uploading.
Preview the Mesh & Choose Format
Inspect the extruded model in your browser. Select STL for a universal mesh, or 3MF for a compact file that modern slicers open natively.
Download & Slice Directly
Click Convert, download your .stl or .3mf file, load it into your slicer, or use our AI FDM Analyzer to test printability instantly.
Don't Waste Filament on Failed Prints — Convert, Verify, and Print Confidently
Generic converters often leave non-manifold edges or walls that are too thin. Convert here, then verify and repair before you slice.
Auto-Manifold Geometry Engine
Unlike generic converters that produce self-intersecting meshes, filled SVG paths are extruded into closed surfaces suitable for FDM or resin slicers.
Seamless AI Printability Check
Once converted, run your model through our FDM Printability Analyzer with 1-click. Detect fragile walls (<0.8mm), dangerous overhangs, and slicing traps before sending it to your printer.
AI Auto-Repair Built-in
Got open curves or inverted normals? Our AI Model Repair Tool fixes holes and topology issues automatically, helping you get a clean slice in Bambu Studio and Cura.
Need More Than a Flat Extrusion?
Want a full 3D sculpture instead of a flat relief? Try our AI Image to STL and AI Text to STL generators to turn concepts into complex organic 3D shapes.
Frequently Asked Questions
Real questions from keychain makers and anyone converting SVG logos into printable STL or 3MF files
Yes. An SVG (Scalable Vector Graphics) is a 2D vector file made of mathematical lines and curves. Our converter takes closed, filled vector shapes, extrudes them along the Z-axis (10 mm by default), and wraps them into a 3-dimensional polygon mesh (.STL or .3MF) that any 3D slicer can read.
Both work in Bambu Studio. STL is the universal single-mesh format. 3MF is a more compact mesh container that Bambu Studio, OrcaSlicer, and PrusaSlicer open natively. This converter exports one solid body either way — it does not split SVG colors into AMS-ready objects. For multi-color prints, paint the model in Bambu Studio or use layer-height color swaps (M600) in Cura/PrusaSlicer.
Most online converters simply extrude paths. If your SVG contains open paths, stroke-only artwork (fill=none), self-overlapping shapes, or duplicate anchors, the mesh can have missing faces or inverted normals. Convert strokes to filled shapes and close open loops in Inkscape or Illustrator before uploading. You can also run our AI 3D Model Repair afterward.
- Build the design from closed filled shapes (not strokes) in Illustrator or Inkscape.
- Upload the SVG and preview the 10 mm extrusion in the converter.
- Export as STL or 3MF — you will get a single solid mesh.
- In Bambu Studio, paint regions or assign AMS colors on the model. In Cura/PrusaSlicer, use layer-height color swapping (M600). Optionally run the FDM Printability Analyzer first.
Yes, but with limitations. A 3D model (STL/3MF) contains volumetric polygon surfaces, while an SVG is flat vector line art. To convert an STL to SVG, software takes a 2D cross-section or silhouette slice of the 3D model at a specific Z-height (commonly used for laser cutting or CNC routing). If you need to convert an STL back to 2D vector, you can slice the model in software like FreeCAD, Blender, or slicer outline exporters.
Yes, converting your SVG to STL or 3MF is completely free with no software installation or registration required. You can also preview and inspect your 3D model directly in your browser. Files are processed locally and never leave your device.
