A method of manufacturing a highly insulating three-dimensional (3D) structure is provided. The method includes depositing a first layer of hollow microspheres onto a base. The hollow microspheres have a metallic coating formed thereon. A laser beam is scanned over the hollow microspheres so as to sinter the metallic coating of the hollow microspheres at predetermined locations. At least one layer of the hollow microspheres is deposited onto the first layer. Scanning by the laser beam is repeated for each successive layer until a predetermined 3D structure is constructed. The 3D structure includes a composite thermal barrier coating (TBC), which may be applied to a surface of components within an internal combustion engine, and the like. The composite TBC is bonded to the components of the engine to provide low thermal conductivity and low heat capacity insulation that is sealed against combustion gasses.

A cementitious mixture for a 3D printer, with improved performance, is described, and its relative use, more specifically for the production of finished products having a complex geometry using a 3D printing apparatus.

A matrix material dispersed with one or more susceptor structures can be formed into a feedstock for an additive manufacturing process. The one or more susceptor structures can be excited by an energy field such as an electric field, a magnetic field, an electromagnetic field, or any combination thereof, to produce heat. The heat that is produced can be transferred to the matrix material that surrounds the one or more susceptor structures to provide heat treatment to the matrix material. The heat treatment can improve the material and mechanical properties of three dimensional objects formed from the feedstock.
