Abstract

Systems and methods are disclosed for a platform to form a three-dimensional article from successively selectively solidified layers of a liquid medium which is soldifiable by the application thereto of a prescribed energy. The platform can be coated or uncoated. The platform can have an array of openings therethrough. Upon completion, the article can be removed from the platform using a punch having a plurality of projections adapted to engage openings in the platform. Alternatively, a tool can be used to push articles from the platform.
