Models –

Most slicers offer several types of supports. Here’s how to decide which one suits your model best:

Tree Supports:
Ideal for organic or curved shapes. They minimize contact points and are easy to remove, making them great for figurines and artistic models.

Grid (Linear) Supports:
Provide strong, stable backing for mechanical parts or models with flat overhangs. Slightly harder to remove but offer excellent reliability.

Organic Supports (in modern slicers like OrcaSlicer or PrusaSlicer):
A hybrid approach that uses minimal material while maintaining stability. Perfect for complex structures.

3. Key Settings to Fine-Tune

a. Support Density

10–20%: Easier removal, faster printing, but less stability.

25–40%: Stronger support for delicate or large parts.
Start low and increase only if your print shows drooping or deformation.

b. Support Interface Layers
These thin layers separate the supports from the model surface.

Add 1–2 interface layers for smooth undersides.

Too many layers can make removal difficult.

c. Z-Distance (Support Gap)
The gap between support and model affects removal ease and surface quality.

For PLA: 0.2–0.3 mm

For PETG or ABS: 0.3–0.4 mm (since they’re stickier materials)

d. Support Overhang Angle
Most slicers start adding supports at 45°.

Lower angles (35–40°) provide more stability for complex parts.

Higher angles (50–55°) reduce support use for simpler geometries.
