    Abstract: A multi-material three-dimensional (3-D) powder bed fusion-based (PBF) printer is disclosed. In one aspect, the 3-D PBF includes a body, a controller coupled to the body, a plurality of cartridges coupled to a print nozzle, an energy source coupled to an upper surface of the body, a deflector for deflecting an energy beam from the energy source, and a build plate on which a build piece can be 3-D printed. Each cartridge may include a slurry in which a specific print material or alloy is suspended. A depositor may selectively deposit the slurry onto the build plate to form a plurality of consecutive layers. For a given layer or a given region thereof, the controller may selectively deposit different amounts of the slurry to produce an alloy having a desired composition. A heating element may be used to vaporize the solvent in the deposited slurry. Using the deflector, the energy source can fuse the regions to sinter the deposited material and in some embodiments, to vaporize the solvent prior to sintering. In other embodiments, the slurries may include different alloys that can be selectively distributed across the layers to form a build piece having desired material characteristics.

    Abstract: One aspect is an apparatus including a node having a socket configured to receive a component and a detachable additively manufactured nozzle co-printed with the node and arranged for adhesive injection between the component and the socket. Another aspect is an additively manufactured apparatus including a first additively manufactured component having an area configured to receive a second additively manufactured component. The first component includes an adhesive channel for injecting adhesive into the area when the second component is being connected to the first component. Another aspect is an apparatus including a plurality of additively manufactured components each having an adhesive injection channel. The components are connected together such that adhesive injection channels are aligned to form an adhesive path that allows adhesive flow between the components.
