Mesh Healer - Fix 3D Print Issues

🔧

Drop an STL, OBJ, or Blender file to analyze and repair. Fixes holes, non-manifold geometry, flipped normals, and separate shells (the Blender internal/external problem). 100% client-side — files never leave your device.

Drop STL, OBJ, or Blend File

Drag & drop or tap to select. Analyzed and repaired entirely in your browser.

Mesh Smoother - Remove Mid-Air Islands

🌲

Drop an STL to remove unsupported "islands" — geometry that prints in mid-air with nothing below it. Build axis is +Z (model stands up). Choose Geometric Trim for a guaranteed island-free result, or Organic Smooth to gently melt the overhangs while preserving the rest at full resolution. Processed on the cluster; large meshes can take a minute.

Drop STL File

Drag & drop or tap to select. Max 100 MB. Sent to the in-cluster smoother service.

Processing Options

⚙

Reconstruction Engine

Auto-selected based on photo count

COLMAP

20+ photos, highest precision

MASt3R

2+ photos, AI sparse recon

✂

Background Removal

Auto-remove backgrounds before reconstruction

New

Uses AI (rembg/U2Net) to remove backgrounds from all uploaded photos before feeding them to the reconstruction engine.

Dramatically improves reconstruction quality by removing background noise
Helps COLMAP/MASt3R focus on the actual object geometry
Replaces background with clean white (optimal for feature matching)
Processing adds ~2-5 seconds per image

🛠

OpenMVS Enhanced Meshing

Higher quality mesh reconstruction

Best quality

Uses Screened Poisson Surface Reconstruction (via pymeshlab) instead of COLMAP's basic Poisson mesher.

Produces smoother, more complete surfaces with fewer holes
Better normal estimation from point clouds
Automatically removes small disconnected components

🎨

Texture Mapping

Project photo colors onto mesh

New

Projects colors from the original photos onto the reconstructed mesh surface.

Generates UV coordinates and a 4096x4096 texture atlas
Exports textured OBJ + MTL files (compatible with most 3D software)
Also generates GLB with embedded textures (for web viewing and AR)
Requires the original (non-background-removed) images for best color

✨

Gaussian Splatting

Photorealistic 3D view (Metal GPU)

New

Trains a Gaussian Splat model from the reconstructed scene using OpenSplat with Metal GPU acceleration.

Produces photorealistic view synthesis (better than textured mesh for viewing)
Uses Apple M4 GPU via Metal for fast training (~12 min for 2000 iterations)
Outputs .ply splat file viewable in browser
Adds ~10-15 minutes to processing time
Not suitable for 3D printing (use mesh output for that)

🔧

Auto-Repair Mesh

Close holes, fix normals, remove artifacts

Automatically fixes common mesh issues that cause slicing/printing failures.

Closes holes, fixes non-manifold edges/vertices
Re-orients face normals, removes duplicates
Essential for clean 3D prints

🖨

Print Preparation

Flatten base, check wall thickness

3D Print

Optimises the mesh for FDM/SLA 3D printing.

Auto-flattens base to sit flat on print bed
Checks wall thickness (warns if <0.8mm)
Ensures watertight mesh

📈

Decimate Mesh

Reduce to max 100k triangles

Reduces polygon count while preserving shape.

Caps at 100k faces using quadric edge collapse
Smaller files = faster slicing
