01 / METHOD
How to use this layer count tool
- Enter the intended model height.
- Set regular layer height and the first-layer height.
- Review the required whole layers and any height added by rounding.
02 / APPLICATIONS
When it is useful
- Estimate layer count before slicing
- Choose a layer height for a target Z resolution
- Understand why sliced height differs slightly from model height
03 / MODEL
Assumptions and limitations
Assumptions
- All heights use millimeters.
- All layers after the first use the regular layer height.
- A partial final layer is rounded up to a complete layer.
Limitations
- Adaptive layers, raft layers, Z compensation, and slicer-specific rounding are not modeled.
- Actual machine motion can differ due to firmware and calibration.
04 / FAQ
Common questions
Why does final height exceed model height?
Printers create discrete layers. If the remaining height is not an exact multiple, one whole final layer is needed.
Is the first layer included?
Yes. It is counted once, with all remaining layers using the regular height.
Does this support adaptive layers?
No. It assumes one regular layer height after the first layer.
