For the second time in two weeks, Pittsburgh hosted an international summit with attendees from around the world, this time focused on the future of manufacturing.

The Global Manufacturing and Industrialization Summit, or GMIS, brought together key players from the global manufacturing and technology communities, including government leaders, industry CEOs and researchers to discuss the future of manufacturing.

The conference chose Pittsburgh based on its renaissance and transition from an economy that relied on heavy manufacturing to an advanced technology and innovation hub in just a few decades.

“The city’s revival is a perfect example to many others around the world facing a similar situation, as well as to developing countries embarking on an advanced industrialization drive for the first time,” conference organizers wrote.

Pittsburgh International Airport CEO Christina Cassotis served as one of many panelists, telling the crowd how the airport has fit into and helped drive the regional transformation.

She pointed to the airport’s Neighborhood 91 additive manufacturing campus, the world’s first end-to-end AM production site that provides all the elements of advanced manufacturing at one location.

“Pittsburgh is unique because if you draw a circle around two hours’ (distance) and then maybe four hours around it, the entire supply chain for a lot of manufacturing exists, but it’s not really connected,” said John Barnes, founder and managing director of The Barnes Global Advisors, one of the partners in the development, who also spoke at the conference

Located on airport property, adjacent to four runways, Neighborhood 91 has potential for rapid part deployment for customers around the world.

“Part of the vision for Neighborhood 91 is to highlight the assets of the region right at the airport so we can build on community strengths,” Cassotis said.

A week earlier, more than 6,000 people from 32 countries around the world converged on Pittsburgh as part of the first-ever Global Clean Energy Action Forum (GCEAF).

The Department of Energy partnered with Carnegie Mellon University to host the three-day GCEAF. Cassotis served as a member of the host committee, and the airport conducted tours for attendees of its microgrid, the first in the world to completely power an airport using natural gas and solar energy.

The Department of Energy used the conference as a platform to launch a competition for $7 billion to establish hydrogen hubs across the country. The money was part of the federal bipartisan infrastructure bill passed last year.
