Claim Text:
1. A method for fabricating a radiation-cured structure, the method comprising the steps of providing a first radiation-sensitive material, the first radiation-sensitive material having a first sensitivity; providing a second radiation-sensitive material adjacent the first radiation-sensitive material, the second radiation-sensitive material having the first sensitivity and a second sensitivity different from the first sensitivity, the second radiation-sensitive material including a photoinitiator not found in the first radiation-sensitive material, the photoinitiator providing the second sensitivity; placing at least one mask between at least one radiation source and the first and second radiation-sensitive materials, the mask having a plurality of substantially radiation-transparent apertures; exposing the first and second radiation-sensitive materials to a plurality of radiation beams through the radiation-transparent apertures in the mask; and forming at least a first construct in the first radiation-sensitive material and a second construct in the second radiation-sensitive material, the first construct and the second construct cooperating to form the radiation-cured structure.
