Print-Ready CAD Checklist: Fixing Models Before They Hit the Slicer

Most print failures stem from CAD models not designed for additive manufacturing.

Model Geometry Validation

No non-manifold edges (watertight solid). No inverted normals. No self-intersecting geometry. Minimum wall thickness maintained.

Design for Manufacturability

Overhangs under 45° or supported. Supports accessible for removal. Clearances added for assemblies. Fillets on sharp corners.

STL Export Settings

Export resolution appropriate (0.01mm detailed, 0.1mm large simple). Binary STL format. Units set correctly. Model centered.

Key Takeaways

  • Fix model geometry before exporting
  • Maintain minimum wall thickness
  • Add appropriate clearances
  • Check STL in slicer before printing
