Abstract
Described are methods and apparatus for the inspection of cured layers of an object during the fabrication of the object using a 3D printing system. A just-printed layer may be inspected by pressing the layer against a pressure-sensitive surface in order to collect information about the layer. For example, a tank may contain a photo-curing liquid polymer, and at its bottom are pressure sensitive elements (e.g., in a backing member or mask). An extraction plate to which the object is affixed may be adjusted so as to position a surface of the object adjacent to the pressure sensitive elements, which report a pressure distribution (e.g., by virtue of a force exerted by a localized region of the object on a localized region of the pressure sensitive elements).
