Slicer Master Guide
Support Settings Master Guide
Dial support placement, interface layers, tree/organic supports, support distance, density, brims, and cleanup strategy for display models and functional prints.
Use this guide in order. Start with the visible symptom, check the simple causes first, then change one setting or mechanical variable at a time. That makes the fix repeatable instead of lucky.
Support goals
- Supports should hold overhangs without welding to the model.
- The best support setting is often model orientation. Rotate before increasing support density.
Key settings
- Support type: normal/grid for stable flat areas; tree/organic for complex display shapes.
- Support overhang angle: lower values create more supports; higher values create fewer.
- Top Z-distance: controls how easily supports release and how clean the underside looks.
- Interface layers: improve underside quality but can make removal harder.
- Support density: more is not always better. Too dense can fuse and scar.
Display model strategy
- Use organic/tree supports where they reduce contact scars.
- Place seams and support contact points where they are less visible.
- Use smaller layer height for faces, armor, creatures, and display busts.
- Preview every support layer before committing to a long print.
Functional part strategy
- Orient for strength first, appearance second.
- Avoid supports in holes, sliding surfaces, threads, and mechanical interfaces if possible.
- Use support blockers around critical fit areas.
Cleanup advice
- Let parts cool before forcing supports off.
- Use cutters and files rather than twisting delicate details.
- For PETG, tune support interface carefully because supports can weld.
