Weak Layer Adhesion Fix Guide
Fix prints that snap, split, delaminate, or fail under light load by checking material temperature, cooling, wall count, print orientation, and filament condition.
Symptoms
- Parts split along layer lines
- Functional prints snap too easily
- Tall prints crack while cooling
- Walls separate under pressure
- Layer bonding changes from one spool to another
Likely causes
- Nozzle temperature too low
- Cooling too aggressive for material
- Incorrect orientation for load direction
- Too few walls or weak infill strategy
- Wet or degraded filament
Fast checks before changing settings
- Check material temperature range
- Compare a warmer test print
- Review part orientation against real load
- Increase wall count before overusing infill
- Check filament condition
Safe fix path
- Identify load direction
- Increase temperature carefully
- Reduce cooling if material allows
- Use more walls/perimeters
- Save a strength profile after test
