The largest specialist event of its kind, AMA: Aerospace, Space and Defense, returns on July 9th. Additive manufacturing in aerospace and defense has entered a more demanding phase. The question is no longer whether metal AM, wire arc additive manufacturing, electron beam powder bed fusion, or advanced materials can produce impressive parts. The harder question is whether these technologies can be qualified, repeated, certified, scaled, and deployed where they matter most: in propulsion systems, aircraft structures, defense supply chains, tactical environments, and mission-critical production programs.
The 2026 edition of 3D Printing Industry’s Additive Manufacturing Advantage: Aerospace, Space and Defense (AMAA 2026) brings together a speaker line-up that reflects this shift from possibility to industrial execution. Presentations will examine modernizing metal AM qualification, tungsten and niobium alloys for high-temperature applications, additive manufacturing machine and material qualification, the role of WAAM in defense autonomy, and the challenge of moving from prototype to mission readiness.
AMAA 2026 takes place online on July 9th. Register for free here.
Speakers include Paul Gradl of NASA Marshall Space Flight Center, Cooper Keller of Divergent Technologies, Jesse Boyer of RTX (Pratt & Whitney), Chase Wallace from GKN Aerospace, Harshil Goel of Dyndrite, Markus Weinmann of TANIOBIS, Gijs van der Velden of MX3D, Jonathan Buckley of JEOL USA, Ben DiMarco of America Makes, Michelle Sidwell of Velo3D, Hugo Sistach of Safran, Karl Littau of Sakuu, Ryan Kirby of Alderman & Company, Alison Wyrick of Outlook Lab, Randy Emert of the Civil Military Innovation Institute, James Ashby of Addlab, Julian Wright of Theta Technologies, and Fabio Sant’Ana of Farcco.
Across the program, a consistent theme emerges: aerospace and defense adoption is now being shaped by evidence, standards, qualification pathways, and operational readiness. NASA will discuss additive manufacturing material readiness and continued work to advance AM for spaceflight applications. Safran will address machine qualification and part certification strategy for aeronautics. America Makes will examine Project AMSCALE and the challenge of unlocking AM qualification at scale. JEOL USA will bring expertise in electron beam powder bed fusion, while TANIOBIS will focus on refractory materials, including tungsten and niobium alloys for high-temperature applications in space.
The agenda also extends beyond conventional AM production. MX3D will explore how WAAM can support strategic autonomy in defense. CMI2 will discuss soldier-led innovation and the transition of ideas from the lab to the tactical edge. Divergent will share lessons from scaling additive manufacturing for aerospace and defense customers, where the real test is not printing a part once, but producing the same part repeatedly, at quality, and at scale. Sakuu will address battery safety and manufacturing for eVTOL applications, including polymeric current collectors designed to reduce thermal runaway risk, weight, and cost.
We are grateful for the support of Dyndrite Corporation, Sinterit, TANIOBIS GmbH, MX3D, and JEOL USA as AMAA 2026 event sponsors.

Who should attend AMAA 2026?
AMAA 2026 is designed for engineers, executives, program managers, procurement leaders, and technical specialists working at the point where additive manufacturing must move from promising capability to dependable production infrastructure. It will be particularly relevant for aerospace, space, defense, eVTOL, and organizations evaluating metal AM, WAAM, EB-PBF, advanced alloys, qualification pathways, and distributed manufacturing models.
The event will also be valuable for OEMs, Tier 1 and Tier 2 suppliers, contract manufacturers, materials companies, software developers, standards bodies, government agencies, research organizations, and investors seeking a clearer view of where additive manufacturing is becoming operationally significant. For those responsible for certification, sustainment, supply chain resilience, part qualification, or production scale-up, the programme offers direct insight from organisations already working through these challenges.
Whether the objective is to understand the latest qualification strategies, assess emerging materials, identify production partners, benchmark aerospace and defense adoption, or connect with the AM community, AMAA 2026 provides a focused forum for separating practical progress from technical noise.
