Investment to Capture Growing Demand for Complex, High-Performance Parts for Aerospace and Beyond

• $60 million expansion to include state-of-the-art additive manufacturing center focused on feedstock materials, processes, product design and qualification
• Investment advances development of proprietary metal powders engineered specifically for 3D printing
• Company unveils Ampliforge™ process, an Alcoa-invented technique combining additive and traditional manufacturing for enhanced properties
• Builds on over 100 years of metal powder production history and 20 years of additive manufacturing expertise with capabilities in California, Georgia, Michigan, Pennsylvania and Texas

Lightweight metals leader Alcoa (NYSE:AA) is expanding its R&D center in
Pennsylvania to accelerate the development of advanced 3D-printing
materials and processes. Alcoa 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, Pennsylvania.

“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 today 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 comprehensive 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 our materials scientists with our manufacturing experts,
  we enable 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.

Construction of the new facility is expected to be completed in the
first quarter of 2016. The project will create more than 100 full-time
positions—including materials specialists, design experts, and process
and inspection technologists—by 2017 and approximately 45 temporary jobs
during construction.

The Pennsylvania Department of Community & Economic Development,
Westmoreland County, Upper Burrell Township and Burrell School District
have agreed to support the project through a mixture of financial
support and tax abatements, resulting in an estimated cost savings of up
to $10 million.

About Additive Manufacturing

Additive manufacturing refers to the production of three-dimensional
products by depositing one layer of material—such as metals and
plastics—on top of another layer, based on a digital model. The process
can help increase productivity, help customers bring products to market
faster and enable the creation of complex designs not possible using
traditional materials and processes.
