Mastering Support Structures
By Inno Uncle
Supports enable complex geometries with dramatic overhangs. Here's how to get them right.
When Do You Need Supports?
Any overhang steeper than 45° from vertical needs supports. Bridges longer than 5mm also benefit.
Support Types
- Tree Supports: Organic, fewer contact points, easier removal. Best for complex models.
- Standard (Linear): Vertical pillars. More material but more reliable for heavy overhangs.
Settings to Tune
- Density: 15-20% is usually sufficient
- Z Distance: 0.12-0.20mm for PLA, 0.16-0.24mm for PETG
- Pattern: Grid (stronger) vs Zigzag (easier removal)
- Support Roof: Highly recommended for smoother supported surfaces
Removal Tips
- Use flush cutters for thick supports
- Heat the part slightly (50°C) for difficult supports on PETG/ABS
- For resin prints, remove supports before final curing
With quality ANTINSKY filament, you can push overhangs further before needing supports.
