STEP to IGES conversion settings explained
When converting STEP to IGES, precision matters for slicing and 3D printing:
- Linear Deflection (Chordal Deviation): Controls how closely triangular facets follow curved surfaces (0.01 mm for precision parts, 0.1 mm for rapid prototyping).
- Angular Deflection: Determines the angle between adjacent facet normals along curved fillets, ensuring smooth circular silhouettes without polygon stepping.
- Manifold & Watertight Validation: Verifies that meshes have no open edges or non-manifold junctions before export into slicing software like Cura or PrusaSlicer.
