Technology & Products

Key Products

Multi-building industrial campus with tenant production facilities; anchor tenant Wabtec (rail parts AM production); FormAlloy DED systems; JEOL, Spee3D and SLM-based metal AM tenants (HAMR Industries); 6K Additive powder production; Cumberland Additive.

Technological Advantage

Physical co-location of feedstock producers, machine OEMs, and post-processing/testing providers eliminates inter-company shipping and qualification delays across the AM production chain; airport-adjacent site enables fast global logistics.

Differentiation

Value Proposition

Condenses and connects every stage of the additive manufacturing supply chain, powder production, machine OEMs, post-processing, testing and inspection, in one physical campus to cut logistics cost and lead time for tenant manufacturers.

How They Differentiate

Unlike consortiums (America Makes) or digital-manufacturing institutes (MxD) that convene members virtually or via shared labs, N91 physically co-locates full-supply-chain tenant companies on a dedicated campus with direct airport access.

Market & Competition

Target Customers

Metal and polymer AM equipment makers, powder/material producers, post-processing and testing firms, and industrial end-users adopting AM production (e.g. rail, aerospace, defense).
