About MeshManiacs

MeshManiacs provides free, fast, browser-friendly utilities for 3D printing enthusiasts, CAD designers, and 3D modellers.

3D printing and mesh manipulation shouldn't require installing expensive software or wrestling with bloated desktop suites just to run diagnostic checks, repair non-manifold edges, or decimate heavy STL files. MeshManiacs was built to solve common 3D geometry headaches directly inside your browser with maximum speed and zero friction.

What We Offer

• STL Repair & Diagnostics: Server-side mesh processing to analyse geometry, detect non-manifold edges, find hole loops, weld duplicate vertices, and auto-fix broken models.
• Mesh Reducer: Browser-based WebGL polygon decimation to shrink STL file sizes while visually preserving model detail in real time.
