Using MCAE and Rapid Prototyping for Casting Design

The conceptualization, design, analysis, prototyping, and testing of a steel casting are described. The methods used include 2D CAD, 3D solid modeling, finite element analysis, Solid Ground Curing rapid prototyping, and laboratory prototype testing. The part was successfully delivered to field testing on time. The use of the MCAE techniques provided a more optimal part more quickly than the use of standard CAD techniques would have provided. A minor cost penalty was paid for the prototype pattern versus conventional prototyping.
