This agreement expands the longstanding relationship between Arconic and Lockheed Martin. The companies currently collaborate on advanced materials and manufacturing projects such as the development of process modeling, simulation tools, and lightweight, corrosion resistant alloys. Arconic also supplies Lockheed Martin with a range of multi-material products for the F-35 Lighting II Joint Strike Fighter aircraft program – from engine to airframe structures – as well as 3D-printed metal parts for service on NASA’s Orion spacecraft.

The Orion spacecraft, slated for an unmanned test flight around the Moon in 2020, will feature over 100 3D-printed components. By manufacturing those geometrically complex components with 3D printing techniques, NASA has replaced between 500 to 600 conventionally manufactured parts and approximately halved the weight of the spacecraft. Lockheed Martin and Boeing are manufacturing the Orion spacecraft, the first deep-space craft manufactured with 3D-printed parts.

“At Lockheed Martin, we are relentlessly finding ways to develop materials that create state-of-the-art advanced capabilities, reduce waste and generate efficiencies in manufacturing practices,” says Rod Makoske, senior vice-president of Lockheed Martin Corporate Engineering, Technology and Operations. “Collaborating with Arconic will help us uncover new ideas for materials development where traditional practices aren’t suitable, investigate more sustainable material compositions and find ways to produce materials more effectively.”
Arconic continues to develop a range of high-performance multi-materials and products for almost every aero engine and airframe platform, including commercial airliners. The company produced components as small as 1/16-inch-diameter aircraft fasteners to the world’s largest fuselage panels and wing skins.

“We have a long history of innovative collaboration with Lockheed Martin across multiple platforms—from single-piece forged bulkheads for the F-35 to 3D-printed parts for the Orion spacecraft—and we are pleased to expand on that relationship with this new agreement,” says Ray Kilmer, executive vice president and chief technology officer at Arconic.
Lockheed Martin is progressing toward the goal of creating greater manufacturing efficiencies, including completing life-cycle assessments on major products, identifying total cost of ownership reductions of $574 million from decreased resource consumption, and impacts on human health and the environment. The company’s 2017 Corporate Sustainability Report details how innovative manufacturing techniques – like industrial 3D printing – can allow for greater resource efficiency, less materials used, and potentially lower greenhouse gas emissions over the full life cycle of a part.
