3D Printing

During my tenure at Lawrence Livermore National Laboratory, I worked on resin and ink formulation for 3D printing. Specifically, I worked on dual-curing resins that leveraged UV-acrylate chemistry to achieve realtime semi-curing of filaments as they were extruded from the nozzle. This allowed for the printing of complex structures that would otherwise collapse under their own weight.
