A layer of a first powder is dispensed in a layer over a build plate. Binder is then selectively applied to hold portions of the layer of first powder together. Unbound first powder is then removed. A second powder is then dispensed in a layer over the build plate and portions of the bound first powder above the build plate. Binder is then selectively applied to hold portions of the second powder together. Unbound second powder is then removed. A third or more different powders can be similarly dispensed and bound to complete a multi-material layer. The process is then be repeated on a next subsequent layer. A curing radiation source can accelerate binding of powder together. Voids can be formed in portions of the layers by dispensing a fugitive material in portions of each multi-material layer.

Fabrication of 3D objects via multiple build platforms
ActiveUS20160200084A1Shorten cycle timeImprove productivityMechanical working/deformationManufacturing driving meansProduction rateMultiple platform
A method is disclosed for improving the productivity of digitally fabricated 3D objects with the same or different shape and material composition. The improved productivity is enabled by the incorporation of multiple build platforms and multiple objects per build platform within a 3D object fabrication apparatus. Some 3D manufacturing processes such as those based on electrophotography require a wait time to condition the build object before the next layer of build and support material can be applied. Under these fabrication conditions, the utilization of multiple build platforms in the 3D object manufacturing process effectively minimizes the wait time between layer deposition so that the productivity for fabricating 3D objects is improved. Furthermore, the incorporation of an additional adjacent set of multiple platforms enables rapid changeover when the fabrication of one set of 3D objects is completed on an adjacent set of build platforms.
