Abstract Scope |
The emergence of volumetric additive manufacturing (VAM) offers fertile opportunities for photopolymer materials development. The support-free layerless 3D printing VAM process presents a different set of constraints for the parameter space of compatible materials, compared to traditional layered photopolymer AM. Along with the breadth of material possibilities available to this process comes the necessity to control resin curing dynamics at all points within the build volume. To do this requires delving in great detail into the curing kinetics, evolution of mechanical properties, and their interplay with total energy delivered to the resin, and the energy dosing rate. We discuss what we have learned about these parameters, and present differences in how major classes of resins such as acrylates and thiol-enes behave from this perspective. We also relate these results to standard layered 3D printing, and discuss how the volumetric AM perspective can also benefit resin development for traditional stereolithography. |
