Inspect 3D STL models with WebGL orbit controls, dimensions, triangle counts, and solid volume
Binary or ASCII format. 100% private in-browser WebGL rendering with zero cloud uploads.
Drag and drop your binary or ASCII .stl file, or click Load Sample Cube.
Rotate, zoom, toggle wireframe, facet normals, or bounding box dimensions.
Review watertight manifold status, volume estimates, or export as clean binary STL.
Parses both binary IEEE 754 float32 facets and ASCII STL lines using JavaScript DataView. Computes volume via signed tetrahedron summation and renders real-time shaded polygons using WebGL and Three.js.
Unlike legacy online converters that transmit entire files to third-party cloud servers, our architecture prevents network bottlenecks, provides near-instant processing, and eliminates cloud wait queues.
Explore 3MF (3D Manufacturing Format) project packages from Bambu Studio, PrusaSlicer, OrcaSlicer, or Cura. Inspect individual part meshes, unit definitions, and package manifests.
Prepare clean, watertight STL meshes for 3D printing. Detects boundary holes, recomputes consistent surface normals via vertex winding, removes zero-area facets, and exports repaired binary STL files.
