Design Considerations

✓ Design Best Practices

  • • Minimum wall thickness: 0.8mm
  • • Avoid overhangs greater than 45°
  • • Design with print orientation in mind
  • • Include chamfers on sharp edges
  • • Consider support requirements
  • • Design for your intended material

✗ Common Design Issues

  • • Walls too thin (under 0.4mm)
  • • Unsupported overhangs
  • • Internal geometry that can't be printed
  • • Features smaller than nozzle diameter
  • • Non-manifold geometry
  • • Excessive detail for print size
Pre-Print Checklist
Ensure your file is ready for high-quality printing

Model Integrity

Manifold geometry (watertight mesh)
No inverted normals
No intersecting faces
Proper wall thickness (min 0.8mm)
No floating geometry

Optimization

Appropriate resolution for print size
Optimized polygon count
Proper scaling and units
Efficient support requirements
Print orientation considered

Technical Requirements

File size under 100MB
Supported file format
No corrupted data
Proper mesh density
Clean geometry
Troubleshooting Common File Issues

❌ File Rejected

Non-manifold geometry

Use mesh repair tools to fix holes and intersections

File too large

Reduce polygon count or export resolution

Unsupported format

Convert to STL or 3MF format

✅ Quick Fixes
