Physics Colloquium: “Photopolymer Additive Manufacturing from NIST to Mines: Novel Voxel & Sub-Voxel-Scale Characterization Throughout All Major Stages of the Printing Process”
CoorsTek Center for Applied Science and Engineering 1523 Illinois St., Golden, CO, United StatesCallie Higgins NIST Abstract: Vat photopolymerization is a powerful additive manufacturing technique that address many applications ranging from personalized medicine to large-scale manufacturing. Unfortunately, these printing processes introduce micrometer-scale anisotropic inhomogeneities due to the resin absorptivity, diffusivity, reaction kinetics, and swelling during the requisite photoexposure. Previously, it has not been possible to characterize high-resolution mechanical […]
