Method and apparatus for freeform construction of objects with improved resolution background

摘要

The fabrication device comprises a build surface for the production of a three-dimensional solid component, a material delivery system configured to deposit one or more build materials on the build surface, at least one of the build materials being at least one of the build- 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 to selectively at least partially solidify successive layers of the three-dimensional solid component by selectively irradiating the photocurable material, and in one example, The lower resolution imaging component solidifies the bulk interior regions and the higher resolution component solidifies the detail boundaries.
