Additive manufacturing expands in U.S. defense production

Additive manufacturing continues to gain relevance in aerospace and defense production as military organizations seek digital manufacturing approaches to improve spare parts availability and supply chain resilience. In this context, Stratasys Ltd. announced the selection of its Stratasys Direct™ manufacturing services unit for the U.S. Department of War Joint Additive Manufacturing Acceptability (JAMA) IV Pilot Parts Program.

Qualification pathways for 3D-printed defense components
The JAMA IV Pilot Parts Program is a multimillion-dollar initiative intended to accelerate the qualification and deployment of additively manufactured parts across military systems. The program focuses on validating the performance and reliability of 3D-printed components before their integration into operational platforms.

Stratasys Direct™, the contract manufacturing division of Stratasys, supplies production-scale additively manufactured parts for defense organizations, supporting operational deployment rather than prototype-only use cases. The company’s involvement builds on existing programs of record with the U.S. Air Force and Naval Air Systems Command (NAVAIR).

Growing role of additive manufacturing in defense supply chains
Additive manufacturing adoption in defense sectors is linked to requirements for precision, scalability and operational readiness. The technology is increasingly used in sustainment strategies, particularly where digital supply chain approaches can reduce spare part lead times and improve equipment availability.

Examples from aerospace sustainment programs
Additive manufacturing has already been applied in active aerospace programs. Within the U.S. Air Force C-17 transport aircraft fleet, Stratasys technologies have been used to produce microvanes intended to improve aerodynamic efficiency. These components have contributed to estimated annual fuel cost savings of approximately $14 million.

Additively manufactured replacement parts are also used to reduce procurement lead times for legacy components, supporting maintenance operations where traditional supply channels may be constrained.

Production-scale additive manufacturing services
Stratasys Direct™ produces more than 100,000 parts annually for defense applications. Programs such as JAMA are intended to accelerate the certification process for these components, enabling faster deployment into operational environments.

The approach combines additive manufacturing platforms with engineering validation processes and contract production services, supporting defense organizations seeking to integrate additive manufacturing into maintenance, repair and overhaul (MRO) workflows as well as broader aerospace manufacturing operations.
