| Abstract | In this talk, we will present our observations of printing kinetics in light-based tomographic additive manufacturing using optical scattering tomography. In particular we report a feature-size dependence on polymerization time that contributes significantly to errors in the printed object: small features tend to polymerize more slowly than large features. Therefore, prints are either missing small features or large features are overexposed. We investigate the cause of this feature size polymerization time dependence and present techniques to correct for these errors. |
