A method of enhancing a performance characteristic of an additive manufacturing apparatus, the method including:

Performance optimization in additive manufacturing

A method of enhancing a performance characteristic of an additive manufacturing apparatus, the method including: (a) dispensing a batch of a light polymerizable resin into the additive manufacturing apparatus, the batch characterized by at least one physical characteristic; (b) determining the unique identity of the batch; (c) sending the unique identity of the batch to a database; then (d) either: (i) receiving on the controller from the database modified operating instructions for the resin batch, which modified operating instructions have been modified based on the at least one physical characteristic, or (ii) receiving on the controller from the database the at least one physical characteristic for the specific resin batch and modifying the operating instructions based on the at least one physical characteristic; and then (e) producing the object from the batch of light polymerizable resin on the additive manufacturing apparatus with the modified operating instructions.

A method of forming the body portion of a three-dimensional object from a polymerizable liquid by the process of continuous liquid interface printing is described. The body portion has a plurality of contiguous segments, and the process includes advancing a carrier for the object away from a build surface while irradiating a build region between the carrier and build surface in a pattern of advancing and irradiating defined by an operating mode. In the present invention, the operating mode is changed at least once during the formation of the body portion for different contiguous segments of the body portion.
