Abstract: A component includes a body, and an interface in the body defining a first and second portion of the body made by different melting beam sources of a multiple melting beam source additive manufacturing system during a single build. The component also includes a channel extending through the body. The channel includes an interface-distant area on opposing sides of the interface, each interface-distant area having a first width. The channel also includes an enlarged width area fluidly communicative with the interface-distant areas and spanning the interface, the enlarged width area having a second width larger than the first width. Any misalignment of the melting beams at the interface is addressed by the enlarged width area, eliminating the problem of reduced cooling fluid flow in the channel.

Abstract: Particle detection systems are disclosed. The particle detection system may include a conduit configured to receive particles removed from a component, and at least one sensor positioned adjacent the conduit. The at least one sensor may be configured to detect a particle characteristic for the particles in the conduit removed from the component. The particle detection system may also include a particle analysis system in communication with the at least one sensor. The particle analysis system may be configured to analyze the particle characteristic for the particles in the conduit to determine if the component is substantially free of particles.
