Systems and methods in which a material or materials (e.g., a viscous material) are printed or otherwise transferred onto an intermediate substrate at a printing unit(s). The intermediate substrate having an image of material printed thereon is subsequently transferred to a sample building unit, and the image of material is transferred from the intermediate substrate to a sample at the sample building unit. Optionally, the printing unit(s) includes a coating system that creates a uniform layer of the material on a donor substrate, and the material is transferred from the donor substrate onto the intermediate substrate at the printing unit(s). Each of the printing units may employ a variety of printing or other transfer technologies. The system may also include material curing, heating, sintering, ablating, material filling, imaging and cleaning units to aid in the overall process.

Carbon fiber reinforced metal matrix composite gears include a planar carbon fiber structure fully encapsulated within a metal matrix formed of sintered metal nanoparticles. The metal nanoparticles can be composed of a metal having a high sintering temperature that would ordinarily destroy the carbon fiber. Novel techniques for making small uniform nanoparticles for sintering lowers the sintering temperature to a level that can accommodate carbon fiber. The composite gears possess high strength to weight ratio.

A composite member is manufactured by a manufacturing method including adding, on a surface of a base member composed of a first material, a second material different from the first material, using additive manufacturing employing directed energy deposition as an additive manufacturing process. The manufacturing method is performed by placing the base member in a machining area of a machine tool configured to perform subtractive machining. Accordingly, a composite member can be obtained that is manufactured through additive manufacturing and that is in a state in which the composite member can be promptly machined.
