Abstract: The present disclosure relates to an energy absorbing three dimensional (3D) structure. The structure may have an outer shell formed from a shell material. The outer shell may have a void forming a core volume. A transformative feedstock is contained in the void. The transformative feedstock is encapsulated within the outer shell, within the void, and provides enhanced energy absorbing properties to the 3D structure.

Abstract: The apparatus generates slices of slender member structures for additive manufacturing of object using a processor having associated non-transitory memory. The memory is programmed to define a graph data structure for storing data representing a plurality of elongated struts each having a predefined spatial position and orientation relative to a three-dimensional reference frame. The memory is further programmed to define a slice data structure for storing data representing spaced apart and parallel two-dimensional slices each passing through the three-dimensional reference frame, the slice data structure storing for each slice a grid comprising a plurality of pixels, each pixel representing a binary state indicating whether material is or is not added in performing additive manufacturing of an object.

Abstract: The present disclosure relates to a method of forming an energy absorbing three dimensional (3D) structure. The method involves forming an outer shell for the 3D structure from a shell material, the outer shell having a void forming a core volume. The method also involves filling the core volume with a transformative liquid. When the 3D structure is fully formed, the transformative liquid is encapsulated within the outer shell and provides enhanced energy absorbing properties to the 3D structure.
