Protocol RL-201 // Jacobs Working Curve

Resin Exposure Time &
Jacobs Working Curve Calculator

Calculate calibrated MSLA and DLP curing times using the Jacobs Photopolymer Equation (Cd = Dp · ln(Emax / Ec)), penetration depth, critical exposure energy, and light engine UV irradiance.

1. Select Photopolymer Resin Chemistry

2. UV Light Engine Optical Irradiance

3. Layer Thickness & Inter-Layer Overcure Margin
