3D Printing Faces 3 Key Barriers to Defense Adoption — MILAM Summit Identifies Roadblocks

Barriers to Defense Adoption

At the Military Additive Manufacturing Summit (MILAM) in Tampa, one theme surfaced repeatedly across panel discussions and conversations with defense officials and industry leaders. The question is no longer whether additive manufacturing can deliver for defense — it's whether the current ecosystem can scale fast enough to meet military needs.

Challenge 1: Supply Chain Fragmentation

Defense contractors and military logisticians face a fragmented supply chain when it comes to AM-certified parts. Unlike traditional manufacturing with established qualified suppliers, the AM supply chain remains inconsistent in quality certification and traceability.

Challenge 2: Qualification and Certification

Perhaps the most persistent barrier is part qualification. Military applications require extensive testing and certification processes that were designed for traditional manufacturing. Additive manufacturing parts must navigate the same rigorous qualification pathways, often without clear guidance on how to translate AM's unique microstructures into accepted certification criteria.

Challenge 3: Workforce Readiness

The third challenge centers on talent. While the defense sector invests heavily in AM equipment, finding and retaining skilled technicians and engineers who understand both additive processes and defense specifications remains difficult. Many programs report that equipment sits underutilized because trained operators are in short supply.

The MILAM summit brought together over 500 attendees from defense agencies, prime contractors, and AM technology providers to address these very issues. The consensus: progress is being made, but the pace of adoption must accelerate as peer competitors invest heavily in AM capabilities.
