Abstract
The present disclosure provides methods and systems for printing a three-dimensional (3D) object. The methods may comprise providing, adjacent to a build surface, a film comprising a polymeric precursor. A sensor may be used to determine a profile of the film. The profile may be indicative of a quality of the film. If the profile meets a quality threshold, at least a portion of the film may be exposed to light to initiate formation of a polymeric material from the polymeric precursor, thereby printing at least a portion of the 3D object.
