How to use this calculator
- Enter the model height and your layer height (mm).
- Read the number of layers.
How it works
Layers = model height ÷ layer height, rounded up.
Worked example
40 mm at 0.2 mm layers. = 200 layers.
Common mistakes
- Finer layers look smoother but print much slower.
- Forgetting the first layer is often a different height.
Frequently asked questions
Does layer height affect strength?
Somewhat — thicker layers can be stronger in Z but coarser; it's a speed/quality/strength trade-off.
