Method of manufacturing a tetrahexaconal truss structure

DETAILED DESCRIPTION What is claimed is: 1.
A method of manufacturing a structure, comprising: forming a first and second plurality of dies, each die including: a plurality of walls; a die apex; a tetrahedron having tetrahedron edges and a tetrahedron apex that coincides with the die apex; a hexagonal base having six base vertices and being located on the opposite end of the die from the die apex, the base being integrated with the tetrahedron such that three walls of the die are parallelograms having four parallelogram edges and four parallelogram vertices, a first parallelogram vertex of each parallelogram wall intersecting the apex of the tetrahedron and the opposing second parallelogram vertex of each parallelogram intersecting a base vertex; creating an upper array of dies having cavities between adjacent dies from the first plurality of dies with the hexagonal die bases being affixed to an upper plate; creating a lower array of dies having cavities between adjacent dies from the second plurality of dies with the hexagonal die bases being affixed to a lower plate; aligning the upper and lower arrays so that the die apices from each array are positioned above the cavities on the other array; placing a core material between the upper and lower arrays; and moving at least one of the arrays near to the other array until the dies from the two arrays are in close proximity with each other to form a core of the structure from the core material having upper and lower surfaces.
2.
The method of claim 1, further comprising: adhering an upper skin to the upper surface; and adhering a lower skin to the lower surface.
3.
The method of claim 1, wherein said core material is molten plastic.
4.
The method of claim 1, wherein said core material is a sheet of metal.
5.
The method of claim 1, wherein each of the dies is individually formed by cutting a piece of a hexagonal bar to create the three parallelogram walls.
6.
The method of claim 3, further comprising: milling down the parallelogram edges to allow the molten plastic to flow between adjacent edges
