Abstract
An apparatus and method for making a three-dimensional object from a solidifiable material using a linear solidification device is shown and described. The apparatus includes a solidification substrate that is tiltable relative to a film about a tilting axis. Layers of the solidifiable material solidify in contact with a film located between the most recently solidified object layer and a solidification substrate that comprises the solidification substrate assembly. The tilting of the solidification substrate relative to the film allows the substrate to be used to squeeze excess solidifiable material from between the film and the most recently solidified object surface while minimizing or eliminating the formation of bubbles in the solidifiable material which can prolong object build times. In addition, tilting the solidification substrate before separating an adhered object surface from the film breaks any vacuum formed between the substrate and the film which reduces the forces involved in separating the object form the film.
