100% Client-Side 3D Mesh Diagnostics & Auto-Repair Engine for Additive Manufacturing & 3D Printing. Automated repair of broken STL, OBJ, and 3MF files directly in browser memory โ Zero-Upload, no cloud dependencies, maximum privacy.
๐ Website & Live Tool: https://meshdoc.svender3d.de/
- All file operations (parsing, diagnostics, ear-clipping hole repair, vertex welding, and export) execute strictly locally inside client browser memory (
Float32Array,Blob,ArrayBuffer). - No server uploads, no cloud dependencies, and no third-party CDNs (all fonts and Three.js modules are self-hosted).
- 0% Idle GPU Utilization: WebGL rendering loop pauses completely during stationary states, eliminating GPU fan noise, excessive power draw, and screen flickering.
- Optimized CAD 3-Point Lighting: Crystal-clear topological inspection without the heavy VRAM depth-pass overhead of dynamic 2048 shadow maps.
- Pre-Repair Inspection: Shows exact verified vertex/triangle counts and explains precise repair operations.
- Post-Repair Audit: Displays full Before โ After comparison with exact delta badges (
ยฑฮ) and verified 100% Watertight / Manifold status.
- Remove Redundant CAD Duplicate Faces: Identifies and cleans overlapping triangles from complex multi-body CAD exports.
- Planar Ear-Clipping Hole Triangulation: Reliable closure of open boundary loops and missing surface patches.
- Topological BFS Surface Normal Alignment: Consistent outward-facing normal winding propagation across shared edge graphs.
- Spatial Vertex Welding: Merges duplicated co-located vertices using a spatial hash table.
- Sharp CAD Facet Shading: Recalculates exact face normals for crystal-clear geometry rendering.
- Live 3D Scanning Laser: Animated visual scanning HUD during the repair process with real-time multi-step progress feedback.
- Zero-Offset Defect Lines: Open edges (Red) and non-manifold edges (Yellow) are rigidly parented to the model for perfect alignment.
- Comparison Modes: Original, Repaired, and Split-View (Side-by-side pre/post inspection).
- Bed Alignment Tools: 1-click drop to build bed (
Z = 0) and centering on a 220 x 220 mm build plate. - Non-Intrusive Sticky Repair Pill: Floating quick-action button docked at bottom-center when scrolling past the dashboard.
- Smooth Ease-In-Out Back-To-Top: High-precision easing navigation (
easeInOutCubic).
- Expandable diagnostic cards explaining the exact root cause in 3D slicers and the applied algorithmic solution.
- Metrics: Triangle count, vertices, dimensions (X ร Y ร Z in mm), surface area (cmยฒ), and signed volume (cmยณ).
- Slicer-Readiness Assessment: Evaluated for Bambu Studio, OrcaSlicer, PrusaSlicer, and Ultimaker Cura.
- Automatic calculation of model weight (g) and filament length (m) for PLA, PETG, ABS, and TPU with customizable infill (0 โ 100%).
- Binary STL: Compact binary STL for all 3D printing slicers.
- ASCII STL: Human-readable STL format.
- 3MF: Modern 3D Manufacturing Format container packaging.
- Wavefront OBJ: Universal 3D polygonal geometry.
