Calculation method
Calculation method
Exposure sequence (seconds)
Sample j uses first exposure + j × increment, starting with j=0. Every exposure must be positive.
Total test layers
Test samples × test layers per sample.
Total exposure-only duration (seconds)
Sum sample exposure times × test layers per sample; excludes lifts and movement.
Symbols and units
- a
- First exposure (seconds)
- b
- Exposure increment per sample (seconds)
- c
- Test samples
- d
- Test layers per sample
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions & limits
Assumptions & limits
- An exposure-test sequence under your supplied settings. Layer count excludes separate base layers, and duration excludes movement and settling. It does not identify a safe or correct resin exposure.
