Integrated design, rapid prototyping, manufacturing processes, and testing has been accomplished in a junior materials and manufacturing class. Students are given a design space- 4 in × 4 in × 1/4 in. Within that volume, they must design a link that may be rapid prototyped, cast, and then tested. The challenge of the project was to develop a link that held the highest load for the least weight. Students designed a link, made a rapid prototyped pattern, cast the component, prepared it for testing, and tested the link in a universal testing machine. The cast material was Al 356. The group that developed a link with the highest load to weight ratio took advantage of the fact the Al 356 alloy may be precipitation hardened.
