Question 1

What are the most urgent AM standards gaps?

Accepted Answer

In-process monitoring requirements for aerospace (ASTM F3318), patient-specific device validation for medical (ISO 13485 / FDA), and cybersecurity for AM data in defense (MIL-STD-3024) are the highest-priority gaps identified.

Question 2

Which bodies set additive manufacturing standards?

Accepted Answer

ASTM International (F42 committee), ISO (TC 261), SAE (AMS-AM), ASME (BPVC for pressure vessels), and FDA (for medical devices) are the primary standards bodies. Joint ASTM/ISO work has produced many of the cross-cutting AM standards in use today.

Question 3

How does AM qualification differ from traditional manufacturing?

Accepted Answer

AM qualification is process-and-material-coupled, meaning a qualified part on one machine and powder lot is not automatically qualified on another. This drives long certification cycles in aerospace, medical, and energy and is the dominant non-technical barrier to scaling.

Question 4

What policy levers accelerate domestic AM capacity?

Accepted Answer

Procurement set-asides for domestically printed parts, workforce training credits, qualification cost-sharing programs, and feedstock supply incentives are the most-discussed levers. Defense and energy sectors have the most active programs in 2024–2026.
