Norway-based Norsk Titanium (NTi) has signed a memorandum of understanding (MOU) with lightweight metals manufacturer Alcoa to launch a joint technology and industrial co-operation programme for 3D printing technology.

With the programme, both companies will identify and explore co-operation projects leveraging their manufacturing expertise and commercial capabilities.

They will also focus on serving the needs of aerospace, defence, energy, automotive and maritime customers.

NTi president Warren M Boley, Jr said: "Through this co-operation programme, we expect to build on our innovative technology capabilities by leveraging Alcoa’s in-depth understanding of lightweight metal components, increase our offerings for aerospace and other end markets, and support our goal of delivering near-net-shape titanium components finished with minimal machining."

Alcoa Titanium and Engineered Products president Eric Roegner said: "Through this joint co-operation programme, we will bring together Alcoa’s unmatched metallurgical know-how and deep aerospace industry relationships with Norsk Titanium’s 3D printing technologies to ultimately accelerate the introduction of advanced manufactured aerospace solutions.

"This programme will further support our efforts to push beyond the limits of today’s additive manufacturing and meet fast-growing demand for 3D printed aerospace parts."

Last July, Alcoa acquired RTI International Metals, a company involved in titanium and specialty metal products and services for the aerospace, defence, energy and medical device markets.

Through the acquisition, Alcoa became a strategic investor in and minority owner of Norsk Titanium.

Currently, with its fourth generation equipment, NTi produces aerospace-grade titanium components.

The company expects to formally conclude the multi-year aviation certification process by next year and begin commercially producing titanium components for customers.

It has recently selected Tronrud Engineering to produce three 3D additive manufacturing machines for commercial and aerospace and defence manufacturers.

The company uses its patented rapid plasma deposition (RPD) process to build titanium parts. The technology transforms titanium wire into complex components in a short period of time. It also lowers production cost by 50% – 75% due to less waste and machining energy.
