Product Structure Evolutionary Design Method Based on IGA and 3D Printing

This study presents a rapid design method of productmodeling and structure condition selecting based on interactive genetic algorithm and 3D printing technology, which give a design pattern to satisfy the function needs. Aiming to products´ shape and structure as the core, we used functional matrix to digitize and describe its demands as well as unify expressing the functional gene. Through 3D printing technology, we dematerialized the design and screened the products which meets the physical and feature requirements. Thus we established a genetic model for the evolution of the design and realization the design method by a tie clasp styling and innovative design.
