Abstract: An integrally-formed multi-property monolithic stainless steel component, a method of fabricating a multi-property monolithic stainless steel component, and a system for fabricating a multi-property monolithic stainless steel component. The integrally-formed monolithic stainless steel component includes, along a longitudinal direction thereof, one or more non-magnetic regions having an austenitic crystalline grain structure and one or more magnetic regions having a ferritic martensitic crystalline grain structure. The integrally-formed multi-property monolithic stainless steel component is fabricated by a selective laser sintering (SLS) assembly having integrated therein a plurality of sub-assembly components, including a selective powder deposition component, a selective laser sintering (SLS) component, and a localized cooling component.

Abstract: Dual-walled fluid transportation systems and related methods. The systems comprise a dual-walled fluid conduit, comprising an outer duct comprising a pair of flared end regions and a central region extending therebetween that define an outer duct internal surface surrounding an outer duct internal volume, an inner duct defining a central conduit, extending within the outer duct internal volume, and comprising a pair of flared end regions and a central region extending therebetween that define an inner duct external surface. The inner duct and outer duct define interlocking geometries and are configured to be supported with an inner duct channel completely separating the inner duct external surface from the outer duct internal surface. The methods include additively forming an outer duct wall and additively forming an inner duct wall within an outer duct internal volume of the outer duct wall with an inner duct channel extending therebetween.

Abstract: A directional flow control device includes a housing extending along a longitudinal axis between an inlet end and a discharge end. The housing holds stator magnets. The directional flow control device includes a flow deflector received in the housing. The flow deflector is rotatable in the housing about a rotation axis parallel to the longitudinal axis. The flow deflector has a flow channel therethrough. The flow channel has an intake bore at a front end of the flow deflector and a discharge bore at a rear end of the flow deflector. The intake bore is coaxial with the rotation axis. The discharge bore is offset from the rotation axis. The flow deflector has rotor magnets aligned with and facing the stator magnets. The stator magnets are energized to cause rotation of the flow deflector relative to the housing.
