SOLVORY · ADVANCED THREE-DIMENSIONAL WORKSPACES · WAVE 23
3D STL Viewer & Mesh Repair Studio
Inspect real STL meshes in an interactive WebGL workspace. Orbit, zoom, measure model dimensions, diagnose boundary edges, rotate, scale, recompute normals and export binary STL or a batch ZIP.
Interactive WebGL · Triangle diagnostics · Limited normal repair · STL/PNG/ZIP exports
Up to 10 STL files in batch and 45 MB per model. The first file opens in the viewport.
Geometry maintenance
These actions can fix orientation/normal issues. They do not fill holes, weld cracks, reconstruct missing surfaces or certify watertight printable meshes. Review output in your slicer before printing.
Interactive mesh viewport
0 triangles · Awaiting geometry
Left drag rotates · Wheel/pinch zooms · Right drag pans. Triangle volume and boundary-edge counts use geometric estimates, not a complete professional mesh-repair algorithm.
Open and inspect STL files online
Import an STL model to display a three-dimensional representation of its triangles. Orbit the camera, inspect grid placement and estimated dimensions, change the surface color, and switch to wireframe to see faceted geometry. Geometry is processed locally in the browser without uploading your model to Solvory’s server.
Boundary and non-manifold edge diagnostics
The studio counts triangle edges that appear once as possible open boundaries and edges shared by more than two faces as possible non-manifold topology. This is a useful heuristic, but duplicate vertices, floating-point precision, degenerate geometry and intentional open surfaces may affect results. Signed-tetrahedron volume estimates are meaningful primarily for closed, consistently oriented meshes.
Mesh repair scope and exports
You can recompute vertex normals, invert triangle winding, rotate and scale the model, and export a new STL file or multiple centered STL models in a ZIP package. STL stores geometry without units, so check size when importing into your 3D printing slicer. Complete hole filling, boolean mesh repair and watertight certification are not provided by this browser edition.

Frequently asked questions
Can I repair a broken STL with this tool?
It can recalculate normals, invert triangle winding and reposition geometry. It does not automatically fill holes or guarantee a watertight print-ready model.
Does it support binary and ASCII STL?
Yes. The STL loader supports both common STL encodings when correctly formed.
Can I export all models at once?
Yes. Upload up to 10 STLs, and the batch export packages centered models with recalculated normals into a ZIP.
