The Avure Quintus hot isostatic press (HIP) being installed at Alcoa Howmet in Whitehall, MI, will treat investment cast and additive manufactured parts, to improve material and structural qualities. It will have a 1.6-m (5.25-ft) diameter work zone and operating pressure of 2,000 bar.

Alcoa Investing in R&D to Maximize 3DP

Aluminum/titanium producer outlines efforts to address demand, expand capabilities for additive manufacturing $60 million expansion for R&D Ampliforge process Materials, testing/certification

Alcoa outlined a $60-million expansion plan for its R&D center outside Pittsburgh, intended to enhance its development capabilities for additive manufacturing materials and processes. It also unveiled a new manufacturing capability it has developed, one of a series it intends to research that would integrate additive manufacturing with its more standard production technologies.

The initiative is particularly relevant to Alcoa’s aerospace manufacturing programs, which involve its primary production activities, investment casting, forging, and other capabilities.

The new hot-isostatic press Alcoa is installing at its investment casting foundry in Whitehall, MI, was initially described as a system to improve aerospace components and structures produced by casting as well as additive manufacturing.

The new Ampliforge process Alcoa outlined as a result of the new research takes a part designed and produced by Alcoa using 3D printing and completes it using the more standard process, i.e., forging. According to Alcoa, it has demonstrated that this new approach enhances the properties of 3D-printed parts, e.g., hardness and strength, compared to additive manufactured parts without further treatment.

Alcoa also said the Ampliforge process reduces material input and simplifies production compared to standard forging sequences.

Ampliforge is being developed on a pilot scale at plants in Pittsburgh and Cleveland.

The Alcoa Technical Center expansion project is underway and expected to be completed in Q1 2016.

Alcoa said its development efforts would concentrate on materials and technologies for a range of 3D printing capabilities in demand for parts in the aerospace, automotive, medical, and building and construction markets.

The new emphasis on additive manufacturing follows Alcoa’s recent concentration on high-value parts and materials for aerospace engines and structures. It also complements its acquisition of RTI International earlier this year, which included several additive manufacturing capabilities that complement Alcoa’s existing resources.

With its new AM research capabilities, Alcoa identified a three-part strategy: developing and producing proprietary aluminum, titanium, and nickel-based powders for 3D printing; combining AM design and production processes, as with the Ampliforge example; and applying its testing and process control capabilities to resolve certification processes for new 3D-printed parts, “starting with aerospace applications,” according to its statement

“Alcoa is investing in the next generation of 3D printing for aerospace and beyond,” stated chairman and CEO Klaus Kleinfeld. “Combining our expertise in metal alloys, manufacturing, design and product qualification, we will push beyond the limits of today’s additive manufacturing. This investment strengthens our leadership position in meeting fast-growing demand for aerospace components made using additive technologies.”
