Abstract
A system for fabricating a radiation-cured structure is provided. The system includes a radiation-sensitive material configured to at least one of initiate, polymerize, crosslink and dissociate with exposure to radiation. At least one radiation source is configured to project a radiation beam toward the radiation-sensitive material. A smart glass device is disposed between the radiation-sensitive material and the at least one radiation source. The smart glass device includes at least one switchable layer selectively operable from an active state to an inactive state. The smart glass device is configured to expose the radiation-sensitive material to a desired exposure pattern when in one of the active state and the inactive state. A method for fabricating the radiation-cured structure is also provided.
