Abstract: A resin composition can includes a first isocyanurate component and a first bonding component bonded to the first isocyanurate component. The first bonding component can be configured to bond to a second bonding component that is bonded to a second isocyanurate component. The first bonding component can be configured to bond to the second bonding component based upon an application of an initiator to the resin composition. In this way, the first isocyanurate component can be coupled to the second isocyanurate component. The resin composition can be either in a pre-cured state in which the first isocyanurate component is not coupled to the second isocyanurate component or in a post-cured state in which at least a portion of the first isocyanurate component is coupled to at least a portion of the second isocyanurate component.

Abstract: Aspects are provided for passivation of waste metal streams. An apparatus may include a three-dimensional (3-D) printer that produces a waste powder during 3-D printing of a printed part, a passivator configured to receive the waste powder and melt the waste powder, and a container configured to collect the molten waste powder. A method may include generating a waste powder during 3-D printing of a printed part, collecting the waste powder in a passivator, heating the passivator to melt the waste powder, and collecting the molten waste powder. Aspects of this disclosure can include the passivator maintaining an inert environment.

Abstract: Techniques for injecting adhesive materials are presented herein. An apparatus in accordance with an aspect of the present disclosure comprises an additively manufactured hollow node having a surface opening, and adhesive material extending from the surface opening into an internal volume of the additively manufactured hollow node. The adhesive material comprises a foaming adhesive. Another method may include preparing at least one undercut region on a surface to accept a cold spray deposition, performing a first cold spray process to deposit material into the at least one undercut region for reducing corrosion on a metallic interface formed at the surface; and performing a second cold spray process to build the metallic interface for joining an aluminum component.

Abstract: The present aspects include a system for de-powdering a three-dimensionally (3D) printed structure. The structure comprising a first component holder configured to removably hold the 3D printed structure at an initial orientation with respect to at least one opening to a hollow portion within the 3D printed structure; a fluid system configured control a fluid to at least apply the fluid to the hollow portion or remove the fluid from the hollow portion to remove a powder from the hollow portion; and a movement system configured to move at least the 3D printed structure or the fluid system according to a movement procedure based on a configuration of the hollow portion.

Abstract: Apparatus and methods for removing and/or destroying support structures associated with objects fabricated using additive manufacturing techniques are presented herein. Structural supports may be used during an additive manufacturing process to prevent deformation of a build piece (e.g., three dimensional (3D) printed structure). In some examples, a build piece may be manufactured such that the structural supports are internal to the completed build piece. However, removing the structural supports may reduce the weight of the build piece and reduce the amount of debris trapped within the build piece. Thus, certain aspects of the disclosure are directed to a hose including a bendable and elongated tube member as well as a fracturing member configured to fracture an internal support structure within an additively manufactured part.

Abstract: The present aspects include an assembly having discretized and segmented joint architecture. The assembly comprises a first structure including an outer wall and an inner wall, wherein the outer wall and the inner wall extend from a base of the first structure, and define a groove, and a plurality of connecting walls extending between the outer wall and the inner wall such that the groove is divided into a plurality of groove segments defined by the outer wall, the inner wall, and the plurality of connecting walls. The assembly further comprises a second structure including a plurality of tongue segments which extend into the plurality of groove segments. A first adhesive is inserted into the groove, thereby bonding the plurality of tongue segments within the plurality of groove segments such that the first and second structures are fixed together.
