WARRENDALE, Pa.— Officials of Norsk Titanium, a supplier of additive manufactured,  aerospace-grade titanium components, and SAE International (SAE) recently released  the first specifications for direct energy deposition additive manufacturing. The specifications use Norsk’s Rapid Plasma Deposition™ (RPD™) process and material requirements, which are currently used by many original equipment manufacturers (OEMs). With the release of the SAE Aerospace Materials Specifications (AMS) documents, the process will be available to a broader base of users across the world.

“Our engineers have thoroughly enjoyed working with the SAE team to validate our proprietary process with the engineering community,” said Norsk President and CEO Michael Canario, in a press release. “RPD™ is truly a disruptive process to the current subtractive manufacturing industry, with wide benefits supporting not only the supplier, but the end-user.”

Developed within the SAE Additive Manufacturing Committee (SAE AMS-AM), the specifications establish the minimum basis required for the procurement of RPD™ Preforms from Norsk by an aerospace or non-aerospace customer. The specifications also support the regulatory certification process by ensuring consistent process and quality control.

The release of the specifications documents, “AMS7004 Titanium Alloy Preforms from Plasma Arc Directed Energy Deposition Additive Manufacturing on Substrate Ti-6Al-4V Stress Relieved” and “AMS7005 Wire Fed Plasma Arc Directed Energy Deposition Additive Manufacturing Process,” are seen as milestone achievements for the metal additive manufacturing industry.

“Given that advanced materials and advanced manufacturing are strategic focus areas for SAE International, we continue to support the aerospace industry’s advances and adoption of additive manufacturing technologies,” said David Alexander, director, aerospace standards, at SAE International. “As well as contributing vital technical expertise, Norsk Titanium played a leadership role as document sponsor in the development of the groundbreaking new specifications and, along with the other AMS-AM output, these new material and process specifications help address the regulatory authorities’ request for guidance material for this critical emerging technology.”

Established by aerospace industry leaders in 2015 and supported by a Federal Aviation Administration tasking request, SAE’s AMS-AM Committee continues to develop aerospace material specifications (SAE AMS) for metal and polymer additive manufacturing to support the needs of the aerospace industry. More than 500 global participants, from more than 20 countries representing aircraft, spacecraft, and engine OEMs, material suppliers, operators, equipment/system suppliers, service providers, regulatory authorities, and defense agencies, are involved in the committee.

Norsk Titanium (www.norsktitanium.com) is a supplier of aerospace-grade, additive manufactured, structural titanium components. The company’s patented Rapid Plasma Deposition™ (RPD™) process is said to transform titanium wire into complex components suitable for structural and safety-critical applications. Norsk Titanium is a tier-1 supplier to Boeing.
