Bridging and Sagging Fix Guide
Improve bridges, drooping spans, sagging overhangs, messy undersides, and support-free design areas using cooling, speed, temperature, orientation, and support strategy.
Symptoms
- Bridges droop between walls
- Overhangs curl or sag
- Undersides look stringy
- Support-free details collapse
- Textured underside looks melted
Likely causes
- Bridge speed/cooling mismatch
- Nozzle temperature too high
- Span too long for the material
- Poor orientation
- Part needs supports or design changes
Fast checks before changing settings
- Run a bridge test model
- Lower temperature slightly for bridge tests
- Increase fan for PLA if appropriate
- Rotate the model for shorter spans
- Use supports when span is unrealistic
Safe fix path
- Test a small bridge
- Tune temperature and fan
- Adjust bridge speed/flow
- Reorient the model
- Use supports only where needed
