Requirements Selection for Rapid Prototyping: Polyphenylsulfone as a Mold Material for Spin Casting Polyurethane Resin

For the development of a rotational symmetrical polyurethane part with a steel reinforcement, a requirement/constraint driven approach to process design has been taken. In this approach a scale model of the process was built using fused deposition modeling rapid prototyping technique, then used to validate design, material and process parameters. After selection and testing on the scaled prototype, results were used to define a full-sized spin casting mold built using Polyphenylsulfone.
