Diagnose and repair non-manifold edges, flipped face normals, and degenerate triangles in browser RAM
Detects non-manifold boundary holes, inverted face normals, and degenerate facets. Prepares watertight meshes for 3D slicers.
Drag and drop your .stl mesh into the repair scanner.
Inspect counts of degenerate triangles, flipped normals, and boundary seams.
Click Execute Auto-Repair and download your cleaned, watertight binary STL.
Scans facet vertices using vector distance thresholds, filters degenerate geometry, recalculates normalized cross products (v2 - v1) × (v3 - v1), and generates clean binary STL buffers.
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.
Free browser-based STL viewer. Orbit, pan, zoom, inspect bounding box dimensions, triangle counts, solid volume, and 3D print filament weight estimates with zero server uploads.
