The intent of this paper is to give the background and details of a project using the concepts of concurrent engineering and design for manufacturing in an educational framework. The project involves the design and production of parts that have simple 2-d shapes with slots. These can be fit together to create a variety of 3-d shapes and figures. These are like children’s toy “puzzle” pieces (building blocks) that can be disassembled and reassembled into new figures over and over. The parts have been produced using the machined mold on a small injection molding machine. This paper discusses the execution of the project from the concept to the design to the production stages. Design for Manufacturing education will be highlighted through this interesting example project.
