Abstract:
A fabrication device includes a build surface for production of a 3-dimensional solid component, a material delivery system configured to deposit one or more build materials on the build surface, at least one of the one or more build materials being a photocurable material, a first imaging component having a first resolution, and a second imaging component having a second resolution different from the first resolution. In this configuration, the first imaging component and the second imaging component are operable individually and in combination together to selectively irradiate the photocurable material to at least partially solidify successive layers of the 3-dimensional solid component In one example, the lower resolution imaging component solidifies bulk interior regions and the higher resolution component solidifies detailed borders.
