In trying to get the accurate and best prototypes for your ultimate objects, a number of issues come up for you to resolve. Whether you adopt the additive or the subtractive method you have to go for the prototype using layering methods. However for resolving the geometrical complexities, traditional subtractive method may fall far short of your expectations. After all the concept of same day parts is something not familiar to subtractive technologies.

Therefore you have to decide your technologies basing on the demands of the situation. Selection of additive technology will largely depend on the particular type of geometry that is required for creating the prototype as well as the end product. Similarly, another item that has been the subject matter of prolonged research and experiment is the use of multiple materials. It is one of the most important considerations for most of the articles to day.

Evolution of rapid prototyping methodologies have resulted in maturing it towards such requirements of multiple materials in an object. More and more applications are now availing the advantages of these rapid prototyping methods. What you can achieve with additive technologies is complete control of the composition. This may not be as convenient with the traditional subtractive method even for the cheaper and insignificant plastic prototype for objects.

Whichever field of operation you may consider, the general as well as the specific control you derive using the rapid prototyping methods cannot be achieved using other traditional technologies.
