The applications for Rapid Prototyping have broadened to the point where the name no longer fits the industry. The name Digital Manufacturing is proposed for the creation of solid articles from computer data without part-specific tooling and minimal geometric restrictions. The current state of the industry is reviewed and applications are classified by material strength and process accuracy. Today designers can have a 3D Printer in their office to build models and prototypes as casually as they would use an office copier. Improved materials and processes are permitting digitally manufactured articles to be used for tooling and end-use applications.
