A fragmentation casing includes a monolithic tube defined by an alternating axial arrangement of first and second rings. Each first ring is a contiguous ring of fused powder defining spaced-apart first elements of the fused powder and at least one second element of the fused powder joining adjacent ones of the first elements. Each second ring is a contiguous lattice of the fused powder. Each of the first elements is contiguous with a portion of the lattice associated with at least one of the second rings.

1. A fragmentation casing, comprising: a monolithic tube being defined by an alternating axial arrangement of first rings and second rings,each of said first rings being a contiguous ring of fused powder defining spaced-apart first elements of said fused powder and at least one second element of said fused powder joining adjacent ones of said spaced-apart first elements, wherein each of said at least one second element is smaller than each of said spaced-apart first elements, andeach of said second rings being a contiguous lattice of said fused powder, wherein each of said spaced-apart first elements is contiguous with a portion of said contiguous lattice associated with at least one of said second rings. 2. The fragmentation casing as in claim 1, wherein said fused powder originates from a bed of a fusable powder material. 3. The fragmentation casing as in claim 1, wherein said fused powder comprises a metal selected from the group consisting of aluminum, titanium, steel, stainless steel, Inconel, tungsten, copper, brass, zirconium, magnesium, tantalum, and alloys thereof. 4. The fragmentation casing as in claim 1, further comprising an outer casing of said fused powder encasing said tube wherein interstices are defined adjacent to at least portions of said contiguous lattice, said spaced-apart first elements, and each of said at least one second element; and a powder material filling said interstices, wherein said powder material and said fused powder are each comprised of identical materials. 5. The fragmentation casing as in claim 4, wherein said identical material is selected from the group consisting of aluminum, titanium, steel, stainless steel, Inconel, tungsten, copper, brass, zirconium, magnesium, tantalum, and alloys thereof. 6.
