ORNL is working with additive manufacturing feedstocks, equipment manufacturers, and end users to revolutionize the way products are designed and built. The research and development in this field are enabling a wealth of opportunities for product customization, improved performance, multifunctionality, and lower overall manufacturing costs. Not only does additive manufacturing remove the traditional limits on part geometry, highly complex components also can be fabricated faster while consuming less material and energy. Additive manufacturing also eliminates the need for expensive part tooling and detailed drawing packages, causing a paradigm shift for the design-to-manufacture process.

Capability Bounds: 

ORNL has more than 20 additive manufacturing capabilities that span metals, polymers, and ceramics systems. Binder jet, laser powder bed, electron beam powder bed, fused deposition modeling, direct deposit laser system, TIG wire fed system, and photopolymer systems are technologies available at the Manufacturing Demonstration Facility (MDF).

Unique Aspects: 

The MDF captures a wide range of additive manufacturing capabilities so that industry may comparatively evaluate the technologies. ORNL is using advanced in-situ NDE techniques with data analytics to evaluate real time the quality of additive manufactured builds. ORNL has also developed new additive technologies, such as the Big Area Additive Manufacturing, that enable increases in deposition rates, decreases in feedstock costs, larger build volumes, and improved material properties.


These facilities are available for various partnership arrangements with industry.
