摘要： Methods and apparatuses for additive manufacturing are described. A method for additive manufacturing may include exposing a layer of material on a build surface to one or more projections of laser energy including at least one line laser having a substantially linear shape. The intensity of the line laser may be modulated so as to cause fusion of the layer of material according to a desired pattern as the one or more projections of laser energy are scanned across the build surface.

摘要： A component for a gas turbine engine can be made via additive manufacturing. During the additive manufacturing process a powder can be used that comprises a superalloy material (12) and carbon nanostructures (14a, 14b). Components made using the powder can have preferred characteristics at certain locations through the use of the carbon nanostructure based additive manufacturing powder.

摘要： An additive manufacturing system includes one or more light sources and one or more light valves that can be written with two-dimensional gray scale patterns that the light valves impose on beams from the one or more light sources to obtain one or more patterned beams. The one or more patterned beams are steered to each area of a plurality of areas on a layer of powder. The two-dimensional gray scale patterns are selected to achieve desired material properties at each pixel position of the patterned beam incident on the layer of powder. The light valves may modulate one or more of amplitude, phase, or coherence. The material properties may include one or more of Young's modulus, porosity, grain size, and crystalline microstructure.
