Various Material used for rapid prototyping
The materials used for prototyping are many and different. The most widespread are: wood, steel alloys (from simple construction steel up to stain-free, modified marks), non-ferrous metals (copper, bronze, aluminum, tin and so on), ABS plastic, Polypropylene, Polyethylene, acrylic glass (PMMA), even some high-grade alloys ( Inconel and other nickel alloys that offer great strength and heat resistance) are used to manufacture some aerospace prototypes. CNC machining technologies have a wide girth here. The cutting tools and the machining equipment is developed so well that you can produce a part of virtually any material as long as it is not flexible.
