WATTS, D.M. and HAGUE, R.J., 2006. Exploiting the design freedom of RM. IN: Proceedings of the 17th Solid Freeform Fabrication Symposium (SFF 2006), Austin, Texas 14-16 August 2006, pp. 656 - 667.
This paper details how Rapid Manufacturing (RM) can overcome the restrictions imposed by the inherent process limitations of conventional manufacturing techniques and become the enabling technology in fabricating optimal products. A new design methodology capable of exploiting RM's increased design freedom is therefore needed. Inspired by natural world structures of trees and bones, a multi-objective, genetic algorithm based topology optimisation approach is presented. This combines multiple unit cell structures and varying volume fractions to create a heterogeneous part structure which exhibits a uniform stress distribution.
