Growth Metrics
Addaero Manufacturing was projected to generate approximately $1 million in revenue in early 2018, just months before its acquisition by Allegheny Technologies (ATI) on July 12, 2018.
Major Milestones
2013: Founded; 2015: AS9100/ISO 9000 certified and ITAR-compliant; 2018-07: Acquired by ATI (Allegheny Technologies Incorporated)
Addaero Manufacturing was an early specialist in Electron Beam Melting (EBM) for aerospace and defense, a niche within metal additive manufacturing that prioritizes high-temperature alloys and low residual stress. Founded in 2013 and based in New Britain, Connecticut, the company positioned itself as a production-ready alternative to traditional casting and forging for mission-critical structural parts.
The company's core technology was EBM, which uses a focused electron beam to melt metal powder layer by layer in a vacuum. This process is particularly suited to reactive alloys such as Ti-6Al-4V and Inconel 718, which are common in aerospace. Addaero offered both rapid prototyping and serial production, backed by AS9100/ISO 9000 certification and ITAR compliance.
Addaero served aerospace primes and defense contractors, producing high-precision components where traceability and repeatability are mandatory. Its customer base overlapped with competitors such as GE Additive (Arcam) and Sintavia, but Addaero differentiated by combining EBM expertise with a fully ITAR-compliant facility.
In July 2018, Addaero was acquired by Allegheny Technologies Incorporated (ATI), a major specialty metals producer. The acquisition integrated Addaero's EBM capability into ATI's broader powder-to-part supply chain, giving ATI an in-house additive manufacturing service for aerospace customers. The deal validated the strategic value of EBM for defense applications but also removed Addaero as an independent service bureau.
