Introduction
Since the mid-1980s Mechanical Engineering, especially in the field of manufacturing, has made many advances. One of these new industry changing advances is rapid prototyping. The great boon to industry that rapid prototyping brought was shorter manufacturing times of product prototypes saving companies great amounts of money, by getting products ready for testing faster and more efficiently to market. The two major types of rapid prototyping processes today are stereolithography and laser sintering. Although these processes perform as expected, they have two major disadvantages. The first one is cost, these machines range from 100,000 to 500,000 dollars. The second one is strength of the prototype. The first process builds prototypes out of a polymer liquid, the second out of miniature metal particles. A need has arisen for prototypes which can be made as solid metal parts for strength. DMDRP was thought up to fill that growing need.
