SolidCAM Additive - Upgrade Your Manufacturing

Share

Neighborhood 91, the additive manufacturing campus adjacent to the Pittsburgh airport, celebrated the opening of two new tenants on Tuesday, April 18, 2023. Solutions provider HAMR Industries and materials manufacturer Metal Powder Works each welcomed visitors for ribbon cuttings and tours of their facilities, located side-by-side in the first building of the campus. Representatives from other Neighborhood 91 resident tenants Wabtec and Cumberland Additive were on hand for the celebration, showcasing the technical range and collaborative nature of this location.

The Neighborhood 91 concept was developed as an end-to-end additive manufacturing campus, featuring parts producers as well as suppliers, service providers and more all in one location. Key partners in the initiative include The Barnes Global Advisors (TBGA), the University of Pittsburgh, and the Pittsburgh International Airport, which is directly adjacent to the campus. Each “neighbor” brings a unique and complementary set of strengths to the location, and these seeds are beginning to cross-pollinate throughout the site.

New Neighbors Entering Production

For Wabtec and Cumberland Additive, the earliest companies to take up residence, Neighborhood 91 is an extension of existing additive manufacturing capacity.

Wabtec’s N91 facility complements binder jetting and other 3D printing capacity located elsewhere in Pennsylvania, with a particular focus on laser powder bed fusion (LPBF) of aluminum parts.

For Cumberland Additive, which is headquartered in Austin, Texas, the location offered a chance for physical expansion to meet customer demand for lightweight metal parts; aluminum part production through LPBF is currently transitioning to the N91 facility.

The shared focus on aluminum has already paid off for these neighbors, with Cumberland recently stepping in to produce a Wabtec part when the latter’s printer was down for maintenance — illustrating the kind of capacity sharing possible here. Electron beam melting (EBM) capacity for titanium will follow soon through a partnership with JEOL.

“The human and capital resources are huge,” says Mark Straszheim, regional director for Cumberland Additive, of the decision to establish a Pittsburgh-area branch. “Why not locate here?”

Now, the latest companies to join the neighborhood will each use the location as primary manufacturing space, with Metal Powder Works producing powders and HAMR supplying parts.

“This facility is a production facility,” says John Barnes, cofounder of Metal Powder Works, which has six machines for metal powder production on premises. The location is convenient to highway and air transportation, but also local to users. “Our customers are here in this building,” he added; indeed, HAMR was even printing parts with MPW copper powder during the event and Cumberland expects to test materials from the company in the future.

Attendees look on as one of Metal Powder Works’ machines turns copper barstock into powder suitable for 3D printing. The technique opens new material opportunities for AM. 

Metal Powder Works, which uses a mechanical process similar to turning to create metal powder from solid feedstock, is focusing initially on the production of copper and high-strength aluminum. Barnes said that its current machine capacity supports production of about 2 kg of material per hour, and that the company expects that figure to rise to 8 kg per hour by the end of the summer.

HAMR, which applies cold spray additive manufacturing by way of a machine from Spee3D, focuses on repair and replacement parts for use in extreme environments. The cold spray technology has the ability to produce metal parts comparable to castings, which can be made faster than most other metal additive systems could produce a part of similar size. That speed is a boon for HAMR, says Michael Schmitt, the company’s CEO and senior research scientist.

HAMR Industries uses cold spray additive manufacturing to produce a range of metal components including parts for defense on short timelines. 

“Our goals are to meet the time frames that conventional manufacturing can’t,” Schmitt says, “or to fill gaps where companies are no longer in business or no longer making the needed part.”

Resilient Manufacturing Ecosystem Project Funded

The celebration came on the heels of the announcement that The Barnes Global Advisors (of which John Barnes is also president) has been awarded $1.95 million to develop “a resilient manufacturing ecosystem” for critical parts needs for the Department of Defense (DOD). The group will create workforce development programs using this award at the Neighborhood 91 campus.

Under the initiative, TBGA will work to drive technology and knowledge (“Tech-Know”) into the production campus; transition into a pilot program focused on addressing DOD supply chain issues and upskilling workforce; and create a blueprint for a Resilient Manufacturing Ecosystem (RME) that can be replicated in other locations to support DOD supply chain requirements domestically and abroad.

The award is funded through the DOD Industrial Base Analysis & Sustainment (IBAS) Program’s National Imperative for Industrial Skills (NIIS) initiative and contracted through Texas A&M’s Engineering Experiment Station (TEES) Secure America Institute. Neighborhood 91 residents Wabtec, Cumberland Additive, Metal Powder Works and HAMR Industries are all partners in the project.
