What is Direct Digital Manufacturing? 

Since the Rapid Prototyping was introduced in 1989 by 3D Systems, CA, there has been significant progress in terms of technology and applications. Rapid Prototyping (RP) allows engineers produce parts directly from 3D drawings eliminating intermediary tools regardless of geometric complexity. RP has been employed to fabricate models as well as manufacturing tools, and even final parts. Hence, Rapid Tooling and Rapid Manufacturing have been added to the terminology. The term "Direct Digital Manufacturing (DDM)" has been commonly used by engineers to describe this cutting-edge technology. In fact, most of the commercially available DDM systems can be used for all three applications.

  • RAPID PROTOTYPING
    Rapid prototyping (RP) allows designers to demonstrate, test, and confirm their designs early and frequently in the product development phase by significantly reducing time and cost.

  • RAPID TOOLING
    Due to the recent advancements in technology and materials, DDM provides an alternative to conventional tool production such as molds, dies, inserts etc. by eliminating intermediary tooling processes.

  • RAPID MANUFACTURING
    Most common applications of this new technology include:

    • Custom-made products
    • Replacement parts
    • Short-run parts production
    • Pre-production parts for testing, trade shows and marker surveys
