Abstract
A three-dimensional object comprises stacked substrate layers infiltrated by a hardened material. Each substrate layer is a sheet-like structure that comprises fibers held together by a sodium silicate binder. The substrate layer material may be non-woven or woven. The substrate layer may be a non-woven fiber veil bound by a sodium silicate binder. The fibers may optionally include carbon fibers, ceramic fibers, polymer fibers, glass fibers, metal fibers, or a combination thereof.
