The 3D Printing File Problem
Without 3D CAD Batch Converter
- Downloaded model won't open in your slicer
- Mesh errors cause failed prints and wasted filament
- Converting one file at a time from CAD software
- No control over mesh density and polygon count
With 3D CAD Batch Converter
- Convert any 3D format to STL or 3MF instantly
- Auto-repair non-manifold edges, holes, and intersections
- Batch convert entire folders for print farms
- Tessellation control — Draft to Ultra quality presets
Built for 3D Printing Workflows
Convert STEP, IGES, OBJ, and any supported format to print-ready STL (ASCII or binary) and 3MF with materials.
Automatic healing fixes non-manifold edges, self-intersections, degenerate faces, open holes, and duplicate vertices.
Fine-tune mesh density. Draft for quick prototypes, Ultra for precision parts. Control chord deviation and angular deflection.
Process entire print queues. Convert and repair hundreds of files automatically. Watched-folder mode for continuous operation.
