Abstract: The present disclosure provides manufacturing systems, devices, apparatuses, methods, and non-transitory computer readable media for detection and/or prevention of harm caused at least in part by malfunction in section(s) of a material conveyance system operatively coupled with a manufacturing enclosure experiencing pressure fluctuation during manufacturing. Coupling or decoupling of pressure fluctuations sensed in various portions of the material conveyance system with those occurring in the manufacturing enclosure, may indicate harm to the section(s) of the material conveyance system. The various portions may or may not be similar to the section(s). The manufacturing system may comprise a three-dimensional printing system.

Abstract: 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.

Abstract: The present application is concerned with a powder mixture for additive manufacturing processes, wherein the powder mixture comprises a duplex steel powder component and an austenitic steel powder component, wherein the powder mixture comprises Cr in an amount of at least 21.3% by weight. The addition of the austenitic steel powder component increases the ductility of the duplex steel and reduces internal stresses which result in cracking in objects build with duplex steel. The present application is further concerned with methods for the preparation of such powder mixtures, methods and devices for the preparation of three-dimensional objects from the powder mixtures and three-dimensional objects, which have been prepared accordingly, as well as the use of an austenitic steel powder to suppress the formation of cracks in duplex steel three-dimensional objects.

Abstract: A method includes forming an initial structure having voids, where the initial structure includes one or more first materials. The method also includes infiltrating one or more second materials into the initial structure, where the one or more second materials are different from the one or more first materials. The method further includes forming a finished structure configured to receive and support one or more heat-generating components. A combination of the first and second materials provides a coefficient of thermal expansion in a portion of the finished structure that substantially matches a coefficient of thermal expansion of the one or more heat-generating components. The finished structure is configured to provide a path to remove thermal energy from the one or more heat-generating components.
