1. A method of forming an article via additive manufacturing, the method comprising steps of:
a. receiving digital data representative of one or both of: a shape of a patient's eye and an appearance of the patient's eye;
b. referencing the digital data comprising one or more of: a shape of a patient's eye and an appearance of the patient's eye, generating an energy transmissibility map comprising a pattern of values representing transmissibility of energy through the article;
c. emitting a first print pattern of polymerizable mixture as droplets, the first print pattern of polymerizable mixture corresponding with the energy transmissibility map; and
d. receiving at least a portion of the first print pattern of polymerizable mixture droplets as a first volume of polymerizable mixture on a receiving surface comprising one or both of: a substrate and previously deposited polymerizable mixture.
