This introductory white paper describes:  

• How design engineers are speeding their development cycles with rapid prototypes made with 3D Printing
• How manufacturers can build finished parts straight from a CAD model using a process called "Direct Digital Manufacturing."

There are many nuances in the different materials and 3D Printing processes that engineers use for prototyping and direct digital manufacturing.

This white paper provides a high level overview of which materials and processes are best suited to prototyping and manufacturing.
