A new style of additive manufacturing facility is emerging in Pittsburgh.
“Neighborhood 91” is billed as:
“The World’s First End-To-End Additive Manufacturing Production Campus.”
With the mission:
“To build an advanced manufacturing ecosystem that condenses and connects all components of the additive manufacturing supply chain into one powerful production center.”
The site appears to be a section of land adjacent to Pittsburgh’s international airport, just at the end of runway 10. Currently, there are six companies resident on the campus, including Cumberland Additive, Metal Powder Works, and HAMR Industries.

What makes this a campus? It seems they’ve collected a number of capabilities related to industrial 3D printing:
- Powder production
- Part production
- Laboratory services
- On-site secure powder storage
- Argon gas partnership
- Multi-axis CNC machining
- Heat treatment
- Reverse engineering
The idea is that by bringing these services together, it forms a kind of proximity effect where new tech ventures can take advantage of the services available in the neighborhood. This would, for example, almost eliminate certain types of shipping because the provider is literally “just next door”. If shipping is required, the airport is just around the corner, leading to significantly simplified logistics and reduced lead times.
Neighborhood 91 is looking for more “residents” (technology providers and users) to occupy spots in the neighborhood. They explain:
“Our network includes advanced manufacturing experts, state and federal government advisors, and real estate specialists, all ready to support and guide you through the process. Whether exploring innovative technologies or securing the ideal location, we have the expertise to answer your questions and help you succeed.”
This is quite an intriguing idea, as it should attract a number of ventures looking to receive those benefits. I have not heard of a similar approach elsewhere, although it’s possible they exist.
And what about the name, “Neighborhood 91”? Where did that come from? They explain:
“Pittsburgh boasts 90 distinct neighborhoods, each unique in its own way. Our campus, the 91st Neighborhood, is a global advanced manufacturing hub, uniting the additive manufacturing / 3D printing supply chain in one dynamic ecosystem.”
