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.
Claims28
A method for printing a three-dimensional (3D) object, comprising:
- (a) providing, adjacent to a build surface, a film comprising a polymeric precursor;
- (b) using a sensor to determine a profile of said film, which profile (i) is indicative of a quality of said film and (ii) comprises a two-dimensional profile;
- (c) determining if said profile meets a quality threshold;
- and
- (d) subsequent to (c), (1) if said profile meets said quality threshold, using a light source to expose at least a portion of said film to light to initiate formation of a polymeric material from said polymeric precursor, thereby printing at least a portion of said 3D object, or (2) if said profile does not meet said quality threshold, adjusting or redepositing said film.
