Optimizing 3D Print Supports
Orientation, support density, and breakaway strategies to save material and improve surfaces.

Summary
Orient parts to minimize overhangs >45°. Use tree supports on cosmetic areas and block supports on structural regions.
1Orientation
Place cosmetic faces upward; split assemblies when support scars are unacceptable.
2Support density
Lower density saves material but risks sag — increase near heavy overhangs.
3Removal and finishing
Plan sandblast or machining on critical mating surfaces after support removal.
Key points
- Minimize overhangs via orientation
- Tree supports on cosmetics
- Post-process mating faces
