Along with many large companies BMW are now using a number of rapid prototyping techniques for design, research and development. BMW are using the new technologies more and more in both their car manufacturing and Formula One racing teams to save time and money.
Rapid prototyping allows BMW to makes educated decision from real life data fast. This helps their racing teams get a competitive edge. Design changes can be created tested and then modified and retested within a number of days. This can save BMW huge R&D costs because more can now be done in less time.
The rapid prototyping used within the car manufacturing side on the business enables engineers and designers to be confident that their designs will be proven before expensive tooling has ever been made.
