Support problems improve when you balance enough contact to hold the overhang with enough gap/interface control to remove supports cleanly. Start with orientation, then support type, interface, density, and Z distance.

What this page helps with
supports, tree supports, support scars, supports hard to remove, support interface, overhangs.
Use this as a landing page first, then jump to the most specific detailed guide below.
What it looks like
- Supports fall over
- Supports weld to the model
- Undersides are rough or scarred
- Tree supports leave marks
- Resin supports fail or leave craters
What usually causes it
- Model orientation creates hard overhangs
- Support density or interface is too aggressive
- Z distance is wrong for nozzle size/layer height
- Tree supports are too thin for the print
- Resin support tips are undersized or badly placed
Do this in order
- Rotate the model before increasing support density.
- Use support interface only where cleaner undersides matter.
- Tune top/bottom Z distance for the layer height and material.
- Use tree/organic supports for organic models and normal supports for flatter mechanical overhangs.
- For resin, check lift forces, support tip size, and island detection.

FAQ
Fast answers
What should I check first?
Support problems improve when you balance enough contact to hold the overhang with enough gap/interface control to remove supports cleanly. Start with orientation, then support type, interface, density, and Z distance.
Should I change many slicer settings at once?
No. Make one controlled change, test again, and save the working result in Profile Vault. Random setting changes make print failures harder to diagnose.
When should I use AI Doctor?
Use AI Doctor when the symptom is unclear, when the print failed in multiple ways, or when you want to connect a failed-print photo to the right guide path.
