Hybrid 3-D-printing process optimizes performance, cost for aerospace parts

By Scott Jenkins |

Alcoa Inc. (Pittsburgh, Pa.; www.alcoa.com) has developed a hybrid technique, called Ampliforge (diagram), that combines additive manufacturing (3-D printing) and advanced forging techniques to improve the performance and reduce the cost of metal aerospace components. The company has produced prototype metal components for several aerospace applications. “Alcoa is taking a comprehensive approach to 3-D printing, including direct and indirect processes,” says Ed Colvin, vice president for new product development at Alcoa. “We understand that one standalone process may not give us the very best part. The hybrid Ampliforge process allows us to combines technologies to optimize performance and cost.” In addition, Colvin says the 3-D printing aspect of the Ampliforge process allows the production of parts with unique geometries that are not cost effective with traditional manufacturing processes alone. Ampliforge involves building a part using 3-D printing, followed by a forging step and a metal-finishing step. The process reduces the amount of material inputs, as well as the number of processing operations, compared to traditional manufacturing approaches. It also improves critical mechanical properties of the resulting parts…
