If a vehicle program being developed primarily in digital design and engineering systems needs to build a quick 3D full size model for reviews or research, a dense foam model is one of the alternatives. Of course, choosing that option assumes that the sophisticated milling equipment is ready to go and that the skilled technicians and model makers can fit your model into their very busy schedule. Once the surface of the foam model has been detailed and painted, plexiglass windows and mockup lights, etc installed, the foam model will appear to be a production vehicle.
