Sintavia, LLC, Davie, Florida, USA, will partner with Taiyo Nippon Sanso Corporation (TNSC), Tokyo, Japan, to develop and commercialise gas flow processes for optimised metal AM. TNSC is said to provide industrial gases and related welding solutions to precision industries globally, and stated that it sees the partnership as a strategic extension of its expansion into Additive Manufacturing, which includes investments and partnerships with a number of AM companies.
Brian R Neff, Sintavia’s Chairman and Chief Executive Officer, commented on the partnership, “Gas flow dynamics are the single most important — and single most overlooked — aspect of successful quality AM builds. 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.”
“TNSC has for many years developed proprietary solutions for industrial welding applications,” added Tadaharu (Ted) Watanabe, TNSC’s General Manager of Global Business Development. “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.”
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 partnership will include the promotion of optimised gas flow strategies to existing customers.
