What are IGES and STL files?
What is a IGES file?
.igesInitial Graphics Exchange Specification CAD file. IGES files are widely utilized across desktop applications and digital workflows, but may require conversion when sharing with recipients who lack native viewing software.
What is a STL file?
.stlStandard Stereolithography 3D triangular mesh format. Converting to STL format ensures universal compatibility across modern browsers, mobile devices, and third-party software suites.
IGES to STL conversion settings explained
When converting IGES to STL, 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.
