Why free browser export matters
A free online 3D modeler is only half useful if you cannot leave with your geometry. Many web tools limit formats on free plans, throttle downloads, or require an account before export. ThreeMesh treats open formats as part of the core product: model in the browser, download standard files, continue in any tool you already use.
Supported formats
| Format | Direction | Typical use |
|---|---|---|
| STL | Import + export | 3D printing, CNC meshes, slicers |
| OBJ | Import + export | General exchange with Blender, DCC, CAD bridges |
| FBX | Import | DCC tools, asset libraries, and game engines |
| GLB / glTF | Import (glTF) + export (GLB) | Web, game engines, AR viewers |
| JSON (.threemesh) | Native save / export | Full ThreeMesh project round-trip |
| PNG | Export | Presentation stills and documentation |
| SVG | Import + export | Editable vector views, diagrams, and documentation |
How to export from ThreeMesh
- Open the free workspace and create or import a model.
- Use groups and components to keep solids clean — especially before printing.
- Choose File → Export and pick STL, OBJ, GLB, PNG, or SVG.
- Download the file to your machine and open it in your slicer, renderer, or engine.
Tips for 3D printing exports
- Prefer solid, closed volumes for reliable slices.
- Watch units — set imperial or metric when you start a model.
- Use solid tools when combining volumes so the mesh stays printable.
- Validate the STL in your slicer before a long print.
