Abstract:
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 to one of radiation frequency and radiation type prior to exposure to a plurality of radiation sources, wherein the plurality of radiation sources includes a first radiation source and a second radiation source; applying a second radiation-sensitive material to the first radiation-sensitive material, the second radiation-sensitive material having a second sensitivity to one of radiation frequency and radiation type that is different from the first sensitivity prior to exposure to the radiation sources, the second radiation-sensitive material different from the first radiation-sensitive material; placing at least one mask between the radiation sources 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, wherein the plurality of radiation beams include a plurality of first radiation beams projected from the first radiation source and a plurality of second radiation beams projected from the second radiation source, and wherein the plurality of first radiation beams is different from the plurality of second radiation beams in one of radiation frequency and radiation type, the first radiation beams selected for the first sensitivity of the first radiation-sensitive material and the second radiation beams selected for the second sensitivity of the second radiation-sensitive material; and forming at least a first construct in the first radiation-sensitive material and a second construct in the second radiation-sensitive material, wherein the difference between the first sensitivity of the first radiation-sensitive material and the second sensitivity of the second radiation-sensitive material results in the first construct being different from the second construct, the first construct and the second construct cooperating to form the radiation-cured structure.
