1. A method for producing a 3-D object, comprising:
reading a file of layers of the 3-D object, layer by layer, each layer having a shape;
for each layer, printing a fluid selectively onto a sheet of composite substrate material, the printing on each said sheet of composite substrate material representing the shape of that layer;
flooding through a trough onto each sheet of composite substrate material a powdered mixture of metal and flux that adheres to the selectively printed fluid on each sheet of the composite substrate material as a printed shape to create at least one composite powdered sheet;
removing excess powder from each composite powdered sheet as each powdered substrate sheet is first printed and subsequently flooded with said powdered mixture of metal and flux; and
stacking the powdered sheets in registered alignment, after excess powder removal, to form a stack of said composite powdered sheets, wherein each sheet in the stack of composite powdered sheets corresponds to a layer in the file of layers.
