STL (Stereolithography) is the most widely used file format for 3D printing. It describes the surface geometry of a three-dimensional object using a mesh of triangular facets. STL files store only geometry data without color, texture, or other attributes.
STL files are commonly used for:
- 3D printing and rapid prototyping
- CAD/CAM software exchange
- 3D scanning output
- CNC machining

STL Viewer FAQ
Does it support both ASCII and binary STL?
Yes! Our viewer automatically detects and handles both ASCII and binary STL file formats.
Can I measure my 3D model?
The viewer displays the bounding box dimensions (width, height, depth) of your model. For detailed measurements, try our Workspace Pro tools.
Does my browser need WebGL?
Yes, WebGL is required for 3D rendering. All modern browsers (Chrome, Firefox, Safari, Edge) support WebGL by default.
Can I view colored STL files?
Standard STL files don't contain color information. The viewer renders models with a default teal material. For colored models, try our GLTF/GLB viewer.
