A method for producing a component layer-by-layer, comprising: providing two or more resin handling assemblies , each resin handling assembly including a resin support which has at least a portion which is transparent, wherein each resin support defines a build surface located in a build zone of the respective resin handling assembly ; executing a build cycle, including the steps of: depositing on each build surface resin which is radiant-energy-curable, wherein the resin on each build surface is a unique material combination; positioning a stage relative to a selected one of the build surfaces so as to define a layer increment in the resin on the selected build surface; selectively curing the resin on the selected build surface using an application of radiant energy in a specific pattern so as to define the geometry of a cross-sectional layer of the component; moving the selected build surface and the stage relatively apart so as to separate the component from the selected build surface; and repeating the cycle, for a plurality of layers, wherein at least one of the layers is cured in each of the build zones, until the component is complete, wherein a separate radiant energy apparatus is provided for each of the build zones, characterized in that the resins include a particulate material filler, further comprising sintering the component to burn out the cured resins and consolidate the filler. providing two or more resin handling assemblies , each resin handling assembly including a resin support which has at least a portion which is transparent, wherein each resin support defines a build surface located in a build zone of the respective resin handling assembly ; executing a build cycle, including the steps of: depositing on each build surface resin which is radiant-energy-curable, wherein the resin on each build surface is a unique material combination; positioning a stage relative to a selected one of the build surfaces so as to define a layer increment in the resin on the selected build surface; selectively curing the resin on the selected build surface using an application of radiant energy in a specific pattern so as to define the geometry of a cross-sectional layer of the component; moving the selected build surface and the stage relatively apart so as to separate the component from the selected build surface; and repeating the cycle, for a plurality of layers, wherein at least one of the layers is cured in each of the build zones, until the component is complete, wherein a separate radiant energy apparatus is provided for each of the build zones, characterized in that the resins include a particulate material filler, further comprising sintering the component to burn out the cured resins and consolidate the filler. depositing on each build surface resin which is radiant-energy-curable, wherein the resin on each build surface is a unique material combination; positioning a stage relative to a selected one of the build surfaces so as to define a layer increment in the resin on the selected build surface; selectively curing the resin on the selected build surface using an application of radiant energy in a specific pattern so as to define the geometry of a cross-sectional layer of the component; moving the selected build surface and the stage relatively apart so as to separate the component from the selected build surface; and repeating the cycle, for a plurality of layers, wherein at least one of the layers is cured in each of the build zones, until the component is complete, wherein a separate radiant energy apparatus is provided for each of the build zones, characterized in that the resins include a particulate material filler, further comprising sintering the component to burn out the cured resins and consolidate the filler. <EOS>
