3D Printing Design Guidelines
- Overhangs — Keep < 45° from vertical for support-free FDM; SLA supports any angle
- Minimum Feature — 0.3mm walls for FDM, 0.2mm for SLA, 0.5mm for SLS/MJF
- Holes — Minimum 1.5mm for FDM, 0.5mm for SLA, 1mm for SLS
- Part Consolidation — Combine multiple parts into one assembly, eliminating joints
- Lattice Structures — Reduce weight by 30-70% while maintaining strength
- Build Orientation — Optimize to minimize supports and maximize surface quality
