A method for producing a component layer-by-layer, comprising: providing two or more resin handling assemblies (12, 112), each resin handling assembly (12, 112) including a resin support (22, 122) which has at least a portion which is transparent, wherein each resin support (22, 122) defines a build surface located in a build zone of the respective resin handling assembly (12, 112); 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 (12, 112), each resin handling assembly (12, 112) including a resin support (22, 122) which has at least a portion which is transparent, wherein each resin support (22, 122) defines a build surface located in a build zone of the respective resin handling assembly (12, 112); 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.
