Abstract Scope |
There is a need to develop technology that allows for the benefits of isotropy afforded by stereolithography to a direct-write UV cure, multi-material application. This work addresses this open question through a multi-nozzle, direct-write manufacturing process with local UV curing. The effects of extrusion methodology, post-process cure time and temperature, and print orientation on the ultimate strength and elastic modulus are discussed. The resulting material has near isotropic mechanical properties, as compared to the highly anisotropic effects in some other extrusion-based printing methodologies. With an eye toward particulate reinforced resins, there is an exploration of composite loaded resins with variable solids loadings printed using this methodology. Through the dual-nozzle approach, variable loadings across a part are demonstrated, thereby opening the door for tailored internal meso-structures of printed resin-based polymers. |
