SOLID IMAGING SYSTEM USING PHOTOHARDENING INHIBITION

摘要

An imaging method and apparatus produces a film of photohardened composition by exposing a layer of photohardenable composition to actinic radiation through a surface of a barrier transparent to the radiation and in contact with the composition at an interface therewith. An inhibition layer is created within the photohardenable composition in contact with the interface that inhibits photohardening of the composition within the inhibition layer during exposure, thereby precluding adhesion of any photohardened composition to the barrier.
