US12674650 - Integrated additive manufacture (AM) of explosive payloads

Integrated Additive Manufacture (AM) of explosive payloads including both energetic and non-energetic components is achieved by controlling the AM processes such that a temperature of any deposited energetic material is bounded below and away from the energetic material's onset temperature to avoid detonation or decomposition of the energetic material during manufacture. This constraint places requirements on the selection of the energetic materials, the AM processes and 3D printer systems for depositing the non-energetic materials and the final composition and density of the non-energetic components.

US12536347 - Helical patterning on a curved surface for additive manufacturing of a fragmentation device

Methods of creating geometry for a fragmentation device are presented. The geometry may be generated using computer-aided design tools. An inner body with a curved surface may be generated. An intersection line may be generated on the curved surface by tracing a helical path. A fragment comprising a fragment surface tangent to the curved surface may be generated and aligned with the intersection line. A pattern of fragments may then be generated based on the fragment, the intersection line, and the curved surface. The geometry of the fragmentation device may be stored for manufacture of the fragmentation device by additive manufacturing.
