Taiyo Nippon Sanso Corporation (TNSC), provider of industrial gases and related welding solutions to precision industries and Sintavia LLC, a leading Tier One metal additive manufacturer have formed a partnership to develop and promote metal additive manufacturing (AM) solutions across key industries.

The partnership involves a technical collaboration to develop and commercialise gas flow processes that optimise the many benefits of metal additive manufacturing. Terms of the deal were not disclosed, and TNSC includes co-investment in Sintavia.

Tadaharu Watanabe TNSC’s General Manager of Global Business Development, commented, “TNSC has for many years developed proprietary solutions for industrial welding applications.”

“We are excited to apply these many years of gas quality control and gas flow experience to the exciting and growing world of additive manufacturing. Sintavia is at the forefront of this technology, and is a quality partner for us to do so. This partnership is an extension of our overall strategy in the additive manufacturing market by investing and partnering with market leading Laser Metal Deposition tool suppliers and metal powder suppliers,” Watanabe continued.

“Gas flow dynamics are the single most important—and single most overlooked—aspect of successful quality AM builds,” said Brian R. Neff, Sintavia’s Chairman and CEO. “In TNSC, we are partnering with a true leader in industrial gas flow optimisation. We look forward to jointly developing and marketing gas flow solutions that will benefit our mutual customers and result in superior builds.”

The optimisation of industrial gas for AM involves perfecting the chemistry, mix, and flow within the build chamber of each manufacturing run. Poorly flowed or poorly mixed gas can result in builds that lack proper mechanical properties, have unacceptable porosity, or a general lack of fusion. It is expected that the newly announced partnership will work with existing customers to promote optimised gas flow strategies that allow for successful end use builds.
