Adaptive Layer Height changes layer thickness along the Z axis based on model geometry. The goal is to reduce visible stepping on curves and shallow slopes without printing the entire model at a very small layer height.
How do you recognize it?
- Finer layers on curves and shallow slopes
- Coarser layers on vertical or less critical regions
- Changing layer heights visible in slicer preview
Common causes
- Local optimization of quality versus print time
What should you check first?
- Inspect transitions in preview.
- Limit min/max layer height to realistic values for the nozzle.
- Consider the effect on layer count and surface consistency in critical regions.
