Scattering model for composite stereolithography @ ACS Applied polymer materials!

Fillers are used to modify the properties of photoresins used in stereolithography (SLA). The resulting composite formulations tend to have a decreasing cure depth for increasing particle loadings due to light scattering. However, some composites show the opposite effect: the cure depth increases with the particle loading. This study provides insights into light scattering in the particle filled SLA resins to unify these seemingly contradictory observations.

A modified Lambert−Beer equation that considers both scattering and absorption was established to evaluate the findings and expand the understanding of scattering in these composite formulations. This unified working curve equation facilitates the further development of particle-matrix SLA resins.
