1. An additively manufactured lattice structure, comprising:
(a) a first three-dimensional lattice comprising a repeating interconnected array of a first lattice unit cell;
(b) a second three-dimensional lattice comprising a repeating interconnected array of a second lattice unit cell, wherein said second lattice unit cell is different from said first lattice unit cell;
(c) a first transition segment interconnecting said first three-dimensional lattice and said second three-dimensional lattice; said first transition segment comprising:
(i) a first three-dimensional transitional lattice comprising a repeating array of said first lattice unit cell; and
(ii) interleaved with and interconnected to said first three-dimensional transitional lattice, a second three-dimensional transitional lattice comprising a repeating array of said second lattice unit cell,
wherein:
said first transition segment has a first portion connected to said first three-dimensional lattice and a second portion connected to said second three-dimensional lattice;
said first lattice unit cells of said first three-dimensional transitional lattice progressively contract in size from said first portion to said second portion; and
said second lattice unit cells of said second three-dimensional transitional lattice progressively expand in size from said first portion to said second portion.
