About AMGTA · Since 2019
AMGTA is the only global, independent, non-competitive organization focused exclusively on additive manufacturing in resource-efficient manufacturing systems.
Founded in 2019 by organizations across the manufacturing ecosystem, AMGTA now has members across five continents — technology developers, manufacturing users, and the internal champions advancing adoption inside their own organizations.
AMGTA builds the argument and evidence base that lets the whole ecosystem communicate credibly about what additive manufacturing actually changes — at the part, system, and enterprise levels.
Our Founding
Why independence matters
Brian Neff, Founder Member, Board Chair, AMGTA
The Green Future of Manufacturing — TEDx, 2019
Brian Neff, CEO of Sintavia, saw additive manufacturing’s potential to simultaneously improve environmental, economic, and performance outcomes. He also recognized that meaningful change at industry scale would require a collective effort no single organization could lead alone—and that for the collective effort to work, the organization carrying it had to belong to the ecosystem, not to any one member of it.
In 2019, Brian convened the founding members — Sintavia, QC Labs, Stratasys, Divergent Technologies, Höganäs, ExOne, and Taiyo Nippon Sanso — to establish AMGTA as an independent non-profit trade association. Founding members contributed the time, capital, and credibility to make AMGTA a working organization from day one. They were joined that same year by participating members across the additive manufacturing ecosystem — technology developers, manufacturers, materials companies, and research institutes whose engagement made AMGTA a viable trade association. AMGTA was deliberately not founded as an initiative inside any member company, no matter how invested.
The structural independence was the point—not because of distrust of any individual member, but because participation, information sharing, and open conversation across the ecosystem only happen when no single company owns the room.
What started as a small group united around shared questions has grown into AMGTA’s current chapter—members across five continents, six years of independent evidence, and a body of work the additive manufacturing ecosystem now references, cites, and uses.
The structural argument outlasts the founding moment. A technology provider explaining additive manufacturing’s value is, necessarily, making a case for their own products. A national association promotes a domestic industry. A consultancy has services to sell. AMGTA’s position requires none of that—which is what makes its framing usable by all sides simultaneously, by technology developers, manufacturing users, and the executives and policymakers both groups are trying to reach.
