1. A three-dimensional article of manufacture comprising a plurality of substrate layers that are infiltrated or coated by, and bound together by, a hardened material, such that the hardened material has a material composition that is different from the material composition of any of the plurality of substrate layers, wherein all of the plurality of substrate layers have a substantially identical material composition and each substrate layer is a sheet-like structure that has a material composition comprising fibers held together by binder consisting only of sodium silicate.
