Key Points
- Lockheed Martin is scaling laser powder-bed fusion (LPBF) additive manufacturing for thermal management components used in hypersonic systems, next-generation aircraft, and electric propulsion platforms.
- Traditional casting, forging, and brazing create supply chain bottlenecks that LPBF can bypass — building precision parts without hard tooling and with shorter lead times.
- The collaboration between Lockheed Martin, Sintavia, EOS, Nikon SLM Solutions, and nTop has delivered a 15–20% reduction in system weight and a 10–15% increase in heat dissipation efficiency for qualifying components.
- Real-time melt pool monitoring and AI-enabled defect detection are compressing qualification timelines by flagging suspect zones during the build, not after.
- Contract manufacturers serving defense primes need to understand this shift now — LPBF qualification requirements and supply chain expectations are already changing at the prime level.
Lockheed's LPBF Push Signals a Real Production Shift
This is not a research announcement. Lockheed Martin is moving laser powder-bed fusion out of the lab and into production for platforms including the UH-60M Black Hawk and the Precision Strike Missile (PrSM). According to 3D Printing Industry's reporting on Lockheed's LPBF thermal management program, the company opened a 16,000-square-foot additive manufacturing facility at its Missiles and Fire Control site in Grand Prairie, Texas in 2024.
That facility includes large-format, multi-laser Nikon SLM Solutions machines, heat treatment equipment, and inspection systems built to support production-rate builds. Infrastructure investment at this scale says something about where the prime sees the technology heading.

What Changed and Why It Matters to the Defense Supply Chain
Thermal management components — heat exchangers, cold plates, and structural thermal interfaces in high-energy electronics and propulsion systems — have traditionally come from casting, forging, and brazing. Those processes work. They're also slow, tooling-intensive, and deeply exposed to raw-material lead times and alloy availability. Hypersonic systems and advanced aircraft can't wait on that supply chain.
LPBF builds parts layer by layer from metal powder, eliminating hard tooling and enabling geometries that conventional machining can't produce. The tradeoff is a qualification burden that has historically been severe. What Lockheed and its partners are doing is attacking that burden directly.
The collaboration with nTop on generative design and parametric optimization has produced measurable results: a 15–20% reduction in overall system weight and a 10–15% increase in heat dissipation efficiency, per the 3D Printing Industry report. Christopher Yakacki, principal of Research Engineering at Lockheed's AMT group, described nTop's contribution as compressing design iteration cycles "from months to minutes."
Work with EOS and Sintavia produced new LPBF processing windows and custom tool path strategies specifically aimed at thin-walled feature resolution. Real-time melt pool monitoring and AI-enabled defect detection are now integrated directly into production workflows, with suspect zones flagged during the build. Paired with computed tomography (CT) inspection of finished parts, this approach accelerates part qualification rather than treating it as an afterthought.
| Capability | Traditional Method | LPBF Approach |
|---|---|---|
| Tooling requirement | Hard tooling required (costly, long lead) | No hard tooling |
| Design iteration | Weeks to months per cycle | Minutes to days with parametric tools |
| Weight optimization | Limited by machining constraints | 15–20% reduction demonstrated |
| Heat dissipation | Baseline casting/forging geometry | 10–15% increase demonstrated |
| Qualification method | Post-production inspection | Real-time melt pool monitoring + CT |
| Supply chain exposure | Casting, forging, alloy lead times | Powder feedstock, build parameter library |

What the Policy Context Tells You
This announcement doesn't exist in isolation. When the Biden administration launched AM Forward in 2022, Lockheed Martin joined GE Aviation, Honeywell, Raytheon, and Siemens Energy as initial participants. The program explicitly targeted small and medium-sized suppliers, pushing additive manufacturing adoption downstream as a hedge against supply chain fragility exposed by pandemic disruptions and geopolitical instability.
Lockheed and Honeywell committed under that framework to research alternatives to traditional forging and casting. That commitment is now producing production-deployed results. The policy tailwind and the operational push are pointing the same direction.
For contract manufacturers in the defense supply chain, this is the signal. Primes are qualifying LPBF parts. They will expect their suppliers to either have compatible capabilities or understand the qualification requirements well enough to support the process. Suppliers who treat LPBF as someone else's problem will find themselves misaligned with where the prime supply chain is going.

What to Do About It
Defense-focused contract manufacturers and engineering teams should be taking specific, near-term actions. The time to understand these requirements is before a program demands them.
These areas deserve attention now:
- AS9100 alignment: Additive manufacturing processes require documentation, traceability, and process control that must map to existing quality management system (QMS) requirements — particularly for build parameter qualification and powder lot control.
- Material qualification exposure: LPBF uses metal powder feedstocks — titanium alloys, Inconel, and aluminum alloys are common in defense thermal management. Understanding feedstock qualification requirements and traceability obligations is foundational.
- CT inspection capability: Computed tomography is emerging as the standard for internal defect detection in LPBF parts. Suppliers need either in-house capability or a qualified inspection partner.
- DfAM literacy: Design for Additive Manufacturing (DfAM) is different from design for machining. Engineering teams supporting LPBF programs need to understand support structure considerations, build orientation effects on mechanical properties, and thermal distortion management.
- Process window documentation: Lockheed's work with EOS and Sintavia produced new processing windows specific to their thermal management geometries. Any supplier entering this space needs documented, qualified process parameters — not just machine access.
This isn't a technology argument. It's a qualification and supply chain readiness argument. The prime is moving. Suppliers who track the shift, build the right documentation infrastructure, and develop LPBF-fluent engineering teams will be positioned to support it.

The Stakes
Hypersonic systems generate thermal loads that demand components operating reliably at the edge of material performance. A thermal management part that fails in a hypersonic vehicle or a next-generation propulsion system doesn't just create a program setback. It affects the service members and mission planners who depend on that system functioning exactly as designed.
Modus Advanced works with engineering teams building exactly these kinds of mission-critical components. Our AS9100-certified processes, vertically integrated manufacturing, and engineering team that works directly with customers on design for manufacturability — that combination exists precisely because these programs can't afford supply chain surprises. One day matters. So does every qualified part.
