SVG to STL Converter for 3D Printing

Use this SVG to STL tool to extrude filled vector paths. Choose the physical width and depth, inspect the geometry, and download a binary STL without uploading your artwork.

Three Steps

How to Convert SVG to STL

The SVG to STL workflow keeps the source, preview, and download together so you can check the model before opening a slicer.

Choose Filled Artwork

Select one SVG under 5 MB. For a predictable SVG to STL result, convert live text and visible strokes to filled paths in your vector editor before uploading.

Set Width and Depth

Choose an output width from 10 to 300 mm and an extrusion depth from 0.6 to 20 mm. The SVG to STL converter preserves the artwork’s proportions and calculates the height automatically.

Preview and Download

Build the preview, rotate or zoom around the solid, and review its dimensions and triangle count. When the SVG to STL preview matches your goal, download the binary file.

Vector Extrusion

Why Use This SVG to STL Converter

Vector paths provide clean boundaries and repeatable physical dimensions without choosing an arbitrary raster resolution first.

Local Processing

The SVG to STL conversion runs in browser memory. Artwork, file names, model dimensions, and geometry are not sent to the site’s servers or analytics.

Vector-Based Edges

Filled paths are extruded from vector outlines rather than image pixels. Curves become printable triangles while straight edges remain clearly defined.

Physical Size Controls

Set width and depth in millimetres before export. The preview reports proportional height, exposing an unexpected aspect ratio before slicing.

Preview Before Export

Orbit, pan, zoom, reset, or switch to wireframe. The preview and download share the same geometry, so the inspected model is the model written to STL.

Holes Stay Open

When SVG fill rules describe counters correctly, interior regions such as the centres of O and A remain holes in the extruded shape instead of becoming solid faces.

No Account Required

Choose a supported file, build the model, and download it without registration. The practical limits are displayed before conversion rather than hidden behind an upload.

Prepare the Artwork

What Makes SVG to STL Results Reliable

A printable extrusion depends on closed, filled vector regions. A design that looks correct on screen can still rely on features that do not describe solid geometry.

Use Filled Closed Paths

Closed shapes with a visible fill provide an area that can be extruded. An open line or stroke has length but no enclosed area, so it cannot create a solid by itself.

Outline Text and Strokes

Convert fonts to paths and expand important strokes before export. This avoids missing typefaces and gives the converter explicit boundaries for every visible letter or line.

Simplify Dense Curves

Thousands of tiny nodes create a heavy mesh. Simplify redundant points while retaining the silhouette and important internal openings.

Understand Separate Shells

Disconnected filled regions remain separate closed shells in one STL. Position them intentionally, or join them in a modelling application when the finished print must be one connected body.

Practical Starting Points

Common SVG to STL Projects

Simple vector artwork produces clear geometry for further refinement.

Logos and Badges

Extrude an original or licensed logo into raised lettering, a badge, or an insert, then adjust mounting features in a modelling application when needed.

Signs and Labels

Turn outlined names, symbols, and room labels into dimensional geometry for prototypes, displays, organisers, or accessibility experiments.

Stamp and Cutter Bases

Create starting geometry from a clean silhouette before adding handles, wall thickness, clearances, or other purpose-specific and safety-critical details elsewhere.

Classroom Prototypes

Move a student-drawn vector shape into a measurable solid without installing desktop CAD, then inspect how curves become triangles.

Continue the Workflow

Next Steps After SVG to STL

Inspect the downloaded mesh, change its 3D format, or use the raster workflow when the source is a photograph rather than vector artwork.

Open the STL Viewer

Load the downloaded file, inspect its dimensions and triangle structure, and compare solid and wireframe views.

Convert STL to OBJ

Move static mesh geometry into OBJ when another modelling or inspection workflow expects that format.

Convert a Raster Image

Use the main image converter for JPG or PNG heightmaps and reliefs that do not begin as vector paths.

FAQ

SVG to STL Questions

These answers cover supported artwork, geometry, output units, privacy, and the limits of a browser-based extrusion.

How does the conversion work?

The tool reads filled vector paths, makes planar shapes, extrudes them to the selected depth, scales the result to the chosen width, and exports binary STL.

Why did my stroke-only drawing appear empty?

A stroke describes a line appearance, not a filled area. Expand the stroke or convert it to an outlined path in your vector editor, save a new SVG, and try again.

Will live text be converted?

Live text is not reliable solid geometry because its appearance depends on fonts and layout. Convert text to paths before using this converter.

Are holes inside letters preserved?

They are preserved when the SVG represents holes with supported fill rules and nested closed paths. Preview the result before downloading and slicing.

What happens to disconnected shapes?

Each disconnected filled region becomes a separate closed shell in the same STL. The converter does not invent a base or bridge between pieces.

Will SVG colors appear in the STL?

No. Standard STL stores triangle geometry and does not retain SVG fills, gradients, strokes, or textures. The preview uses one neutral material to show shape.

Are the output dimensions really millimetres?

The coordinates are generated using the displayed millimetre values, but STL itself stores no unit label. Confirm the import unit and final dimensions in your slicer.

Is my artwork uploaded or stored?

No. Parsing, extrusion, preview, and export happen locally. The site does not receive SVG content, file names, model geometry, or derived measurements.
