Abstract: A method of creating an article of manufacture is provided, which includes directing multiple laser beams to a single galvanometer; and dynamically repositioning the multiple laser beams in counterpart paths using the single galvanometer to shine the multiple laser beams on and melt a first powder material and, upon solidification of the melted first powder material, forming a first series of duplicate three dimensional structures, where each of the multiple laser beams is used to form at least one of the first series of duplicate three dimensional structures.
