Abstract
Improved methods and apparatus for additive manufacture of an article with surface qualities conducive to use as an optical element, such as a contact lens. The improvements are directed to repeated application of a monomer according to a pattern of energy transmissibility, such as gray scale image. The method includes intermittent pinning of deposited polymerizable mixture and final cure of the deposited polymerizable mixture. A pattern of multiple defined areas may be manufactured, with each area representing an amount of energy transmissibility associated with that area. Each area may have a light value based upon a scale, such as an 8 bit, 16 bit, 32 bit, 64 bit scale or other scale. In some embodiments, each area may refer to a smallest single component of a digital image.
