The document discusses the convergence of topology optimization and additive manufacturing. It describes how topology optimization originated in 1892 with Wolff's Law on bone adaptation and expanded with early research at the University of Michigan in the 1990s. Additive manufacturing also began gaining excitement in 1994. The combination of the two allows generating designs that were previously impossible to manufacture and opens opportunities to expand their usage. The synergy between topology optimization and additive manufacturing allows for easier application to designs, a wider range of materials, and appropriateness to more parts.
