Tips for Getting Started with 3D Modeling
Starting with 3D modeling requires understanding fundamental workflows and avoiding common pitfalls. These guidelines help create successful prints from digital designs.
Basic Workflow Steps
- Start with reference images or sketches to guide the modeling process
- Block out basic shapes using primitives (cubes, cylinders spheres)
- Apply modifiers to refine geometry details
- Check model topology for manifold edges meshes
- Set appropriate wall thickness (minimum 1.2mm for most printers)
- Orient models for optimal print direction
- Export files in STL format at proper scale
- Verify model integrity using mesh analysis tools
- Create test prints of complex sections
- Document successful settings parameters
- Creating non-manifold geometry (gaps holes floating faces)
- Using meshes with incorrect normals orientation
- Designing overhangs beyond 45-degree angles
- Making walls too thin (less than recommended thickness)
- Ignoring support material requirements
- Placing insufficient infill percentage
- Creating models larger than build volume
- Using incompatible file formats
- Failing to check mesh intersections
- Neglecting to scale models properly
| Design Parameter | Recommended Value | Common Error Range |
|---|---|---|
| Wall Thickness | 1.2-2.0mm | <0.8mm |
| Overhang Angle | <45 degrees | >60 degrees |
| Minimum Detail | 0.4mm | <0.2mm |
| Support Spacing | 2-4mm | >6mm |
| Infill Density | 15-20% | <10% |
