ADDITIVE MANUFACTURING SYSTEM FOR LIGHTWEIGHT LARGE SCALE SANDWICH STRUCTURES WITH TAILORABLE CORE DENSITIES

A method of additive manufacturing including generating a stress model driven slice file for a structure (206) and additively manufacturing a variable density foam core with respect to the stress model driven slice file such that a density of the variable density foam core is varied relative to a mo...

Summary:A method of additive manufacturing including generating a stress model driven slice file for a structure (206) and additively manufacturing a variable density foam core with respect to the stress model driven slice file such that a density of the variable density foam core is varied relative to a modeled stress in the structure manufactured with the variable density foam core (208). An additively manufactured structure (300) includes a composite skin bonded to the variable density foam core.
