| Abstract Scope |
Volumetric Additive Manufacturing (VAM) is a novel photopolymer additive manufacturing technique that allows for the all-in-one fabrication of parts without the need for support material, in geometries not available in other AM techniques, and with smooth surfaces, which minimize the need for post-processing procedures, such as polishing. While previous work has successfully demonstrated fabrication of glass micro-optics using the VAM technique, limitations in resin formulation have prevented fabrication of parts with cross-sections larger than a few square millimeters. Here, we report on our progress in formulating a glass photopolymer resin that allows for fabrication of parts with cross-sections in the realm of square centimeters, in addition to our work in creating various glass resins with varying refractive indices.
This work performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344 within the LDRD 22-ERD-012. LLNL-ABS-847039. |
