Welcome to the Direct Digital Manufacturing Design Competition!

Sponsored by the Direct Digital Manufacturing Tech Group of RTAM/SME

This Year’s Topic: Additive Manufactured Machines


Design Challenge
For 2014, student designers are asked to utilize additive manufacturing (AM) for the creation of nine-piece car body. The winning design will be distributed by show-floor exhibitors as pieces for the RAPID Challenge Puzzle.

Ultimately, the result will be a functional mechanism or assembly with interlocking parts. The geometry of the design must be defined within a 3D CAD system capable of producing robust STL files. The deliverable shall include a complete bill of material/parts list where file transfer enables reproduction of the nine-piece car body.

Overview
Additive manufacturing embraces a wide range of materials and derivative processes building parts suitable for end-use service. The virtually unlimited design freedom enabled by additive manufacturing allows the creation of shapes and the integration of feature and function that previously often required complex, costly and long lead-time tooling. Employment opportunities for creative individuals are growing while industry adopts AM methods. Ready access to workstations and service providers make the Internet a growing marketplace for public AM gadgets.

This year’s challenge seeks to showcase the speed and versatility of AM in the age of Web sharing and point-of-use manufacture. As the designer, you are only limited by your imagination. Use this opportunity to reveal your Additive-Manufactured Car Body as a puzzle everyone can appreciate. The nine car-body components will be mass produced and available to RAPID 2014 attendees only in care of select exhibitors.
