Claim 0:
1. A method of forming an ophthalmic lens via additive manufacturing, the method comprising the steps of:
a. emitting a first print pattern of polymerizable mixture as droplets, the first print pattern of polymerizable mixture corresponding with an energy transmissibility image;
b. receiving the first print pattern of polymerizable mixture on a receiving surface, the receiving surface comprising one or both of: a substrate and previously emitted polymerizable mixture;
c. exposing the first print pattern of polymerizable mixture on the receiving surface to a pinning process causing partial polymerization of the first print pattern of polymerizable mixture;
d. emitting a second print pattern of polymerizable mixture;
e. allowing physical forces comprising surface tension to act on at least some of the second print pattern of polymerizable mixture and smooth a surface of the second print pattern of polymerizable mixture;
f. integrating at least some of the second print pattern of polymerizable mixture with the first print pattern of polymerizable mixture emitted as droplets to form a combined volume of polymerizable mixture; and
g. curing the combined volume of polymerizable mixture.
