NOVELTY - System (S1) (2) comprises: radiation sensitive material (6) configured to at least one of initiate, polymerize, crosslink or dissociate with exposure to radiation; at least one radiation source configured to project a radiation beam with a vector that does not intersect a radiation-sensitive material; and radiation directing device selectively positionable between active state to inactive state, where the device in active state is configured to receive radiation beam projected by radiation source directly from radiation source and direct radiation beam toward the radiation sensitive material.    USE - The system is useful for fabricating a radiation-cured component (claimed), which is useful as fuel cell component such as diffusion media, bipolar plates or sub-gaskets.    ADVANTAGE - The system: provides complex or multi-layered radiation-cured structures without employing costly and inefficient masking techniques, processing steps and cleaning steps, hence it is efficient and cost effective; and utilizes the radiation source that can be rapidly and readily switched on and off, hence prevents a formation of undesirable dragging radiation-cured structures, and provides the radiation-cured structures having desired angles and shapes.    DETAILED DESCRIPTION - System (S1) (2) comprises: a radiation sensitive material (6) configured to at least one of initiate, polymerize, crosslink or dissociate with exposure to radiation; at least one radiation source configured to project a radiation beam with a vector that does not intersect a radiation sensitive material; and a radiation directing device selectively positionable between an active state to an inactive state, where the radiation directing device in the active state is configured to receive the radiation beam projected by the radiation source directly from the radiation source and direct the radiation beam toward the radiation sensitive material, and the radiation directing device in the inactive state is configured to receive the radiation beam projected by the radiation source directly from the radiation source and direct the radiation beam away from the radiation sensitive material. An INDEPENDENT CLAIM is also included for a system (S2) for fabricating a radiation-cured component, comprising: the radiation sensitive material; a first radiation source disposed adjacent a first side of the radiation sensitive material and configured to project a first radiation beam with a vector that does not intersect the radiation sensitive material; a second radiation source disposed adjacent a second side of the radiation sensitive material and configured to project a second radiation beam with the vector; and a digital micromirror device having many micromirrors arranged in an array.
