Alcoa announced it is expanding its R&D center in Pennsylvania to accelerate the development of advanced 3D-printing materials and processes. The company will produce materials designed specifically for a range of additive technologies to meet increasing demand for complex, high-performance 3D-printed parts for aerospace and other high-growth markets such as automotive, medical and building and construction. The $60 million expansion is under construction at the Alcoa Technical Center, the world’s largest light metals research center near Pittsburgh, Pa.

“Alcoa is investing in the next generation of 3D printing for aerospace and beyond,” said Alcoa Chairman and Chief Executive Officer 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.”

Demonstrating this integrated strategy, the company recently unveiled its Ampliforge process, a technique combining advanced materials, designs and additive and traditional manufacturing processes. Using the Ampliforge process, Alcoa designs and 3D-prints a near complete part, then treats it using a traditional manufacturing process, such as forging. The company has shown that the process can enhance the properties of 3D-printed parts, such as increasing toughness and strength, versus parts made solely by additive manufacturing. Further, the Ampliforge process significantly reduces material input and simplifies production relative to traditional forging processes. Alcoa is piloting the technique in Pittsburgh and Cleveland.

The company’s approach to advancing additive manufacturing includes:

  • Materials leadership: Alcoa’s material scientists will produce proprietary aluminum, titanium and nickel powders designed specifically for 3D-printing. These powders will be tailored for various additive manufacturing processes to produce higher strength 3D-printed parts, and meet other quality and performance requirements. Alcoa has a long history in metal alloy and powder development, having invented over 90 percent of the aluminum alloys used in aerospace today and with a 100-year history in aluminum metal powder development for rocket fuel, paint and other products.
  • Combination of process and design: Alcoa will further its development of advanced 3D-printing design and manufacturing techniques – such as Alcoa’s Ampliforge process – to improve production speeds, reduce costs and achieve geometries not possible through traditional methods. Direct production of 3D-printed metal parts represents a new way to manufacture aerospace components and requires a new suite of innovative design tools to realize its full potential. By connecting their materials scientists with their manufacturing experts, the company enables a rapid development feedback loop to inform new software tools and processes that take full advantage of additive capabilities.
  • Qualification expertise: With the industry’s longest-running history of certifying aerospace components and qualifying processes, Alcoa will use its testing and process control expertise to overcome challenges with certifying new 3D-printed parts, starting with aerospace applications.

This expansion of the Alcoa Technical Center builds on Alcoa’s additive manufacturing capabilities in California, Georgia, Michigan, Pennsylvania and Texas. The company has been creating 3D-printed tools, molds and prototypes for the past 20 years and owns and operates one of the world’s largest HIP (Hot Isostatic Pressing) complexes in aerospace, a technology that strengthens the metallic structures of traditional and additive manufactured parts made of titanium- and nickel-based super-alloys. Through the recent RTI acquisition, Alcoa gained 3D printing capabilities in titanium, other specialty metals and plastics for the aerospace, oil and gas, and medical markets. This expansion positions Alcoa to industrialize its advanced 3D printing capabilities across these and other manufacturing facilities.
