Neighborhood 91 (N91), the advanced manufacturing campus at Pittsburgh International Airport, is expanding with a new 108,000-square-foot building intended to attract additional businesses and jobs to southwestern Pennsylvania. Officials broke ground on the facility as Allegheny County Executive Sara Innamorato joined Christina Cassotis, chief executive officer of the Allegheny County Airport Authority, which owns the property, and Donald F. Smith Jr., president of the Regional Industrial Development Corporation, the site’s master developer, along with other civic and business leaders.
Buildout of the campus is planned to reach up to 195 acres when completed. Construction of the new building is expected to cost $16 million, with funding from Allegheny County and the Commonwealth of Pennsylvania, in addition to equity from RIDC. Neighborhood 91’s first building is already fully occupied by HAMR Industries LLC, Cumberland Additive, Metal Powder Works, RJ Lee Group, Westmoreland Mechanical Testing and Research, and JEOL Inc. That first phase provides an existing tenant base as work begins on the next building.
Innamorato linked the project to employment and industrial growth in the county. “Growing jobs and economic development in our region is a key priority and I’m thrilled to support such an innovative advanced manufacturing campus next to the airfield at Pittsburgh International Airport,” she said. “Anchored by our region’s strong academic institutions, advanced manufacturing continues to grow in Allegheny County, and I look forward to the continued building of the Neighborhood 91 campus.” Cassotis pointed to the airport location and the site’s role in the region’s manufacturing plans. “Pittsburgh has the expertise and resources to be the global home of advanced manufacturing and with Neighborhood 91 continuing to grow, we are making that home at Pittsburgh International Airport,” she said. “I’m proud to break ground on yet another building to help meet the demand for this end-to-end campus. Thanks to our partners at RIDC as well as federal, state and county leaders for all of their support in moving our region forward.”
Smith placed the expansion within a longer regional manufacturing history. “The Pittsburgh region has a long history as a center of advanced manufacturing and materials science,” he said. “N91 is building on that tradition and, with its location adjacent to Pittsburgh International Airport, is poised to become a foundational asset for southwestern Pennsylvania. We are already in discussion with prospective tenants and, with the continued support of the ACAA and the County Executive, we’re looking forward to building the momentum.” His remarks also tied the new facility to ongoing tenant recruitment as the campus adds space.
University of Pittsburgh’s Center for Advanced Manufacturing forms part of the broader research and development network around the site, coordinating research and academic activities and aligning technology with potential industrial applications by drawing on the university’s research strengths for industry and government engagement. Carnegie Mellon University’s Next Manufacturing Center also supports that regional ecosystem by applying engineering and data science expertise to additive manufacturing, including work through the Manufacturing Futures Institute at Mill 19. Mill 19 itself includes tenants such as Motional, the autonomous vehicle company, the Advanced Robotics in Manufacturing Institute, YKK AP, and Instinct Robotics.
Advanced Manufacturing Facilities Expand Across the US
Industrial-scale additive manufacturing capacity is also expanding in Pennsylvania. ATI, a US producer of high-performance materials, opened a 132,000-square-foot Additive Manufacturing Products facility that brings design, 3D printing, heat treatment, machining, and inspection together under one roof. Certified to ISO 9001 and AS9100D standards, the site can produce metal parts up to 1.5 meters tall and has already secured a first production contract from Bechtel Plant Machinery Inc. for components used in the US Naval Nuclear Propulsion Program. That opening offers a closer benchmark for the kind of integrated, production-oriented additive manufacturing infrastructure now taking shape in the region.
