Lockheed Martin partners with Sintavia, EOS, Nikon SLM, and nTop to advance LPBF for defense thermal management

Lockheed Martin has announced a multi-partner initiative to mature laser powder bed fusion (LPBF) for production of thermal management components across defense platforms, including the UH-60M Black Hawk helicopter and Precision Strike Missile. The company structured its LPBF development around four specialist partners: Sintavia, EOS, Nikon SLM, and nTop. Working with EOS and Sintavia, Lockheed Martin co-developed a new LPBF processing window and bespoke tool path strategies to improve feature resolution and producibility, while nTop's generative design tools delivered a claimed 15-20% reduction in overall system weight and a 10-15% improvement in heat dissipation efficiency. The effort builds on a 16,000-square-meter AM facility opened in 2024 at the company's Missiles and Fire Control site in Texas, housing large-format multi-laser machines alongside heat treatment and inspection equipment.

This partnership represents a significant step in the aerospace qualification grind pattern, where a prime contractor systematically embeds AM into certified production workflows rather than treating it as a prototyping novelty. For Sintavia, the deal provides a direct channel into Lockheed Martin's defense supply chain, validating its position as a qualified production partner rather than just a service bureau. The collaboration also demonstrates the growing importance of thermal management as a killer application for metal AM in defense, where copper alloys and complex internal channel geometries are difficult to produce conventionally. The inclusion of real-time melt pool monitoring and AI-enabled defect detection signals that qualification confidence, not just part production, is the primary bottleneck being addressed.

For Sintavia, this partnership locks in a multi-year production relationship with a Tier 1 defense prime, moving beyond project-based work into embedded supply-chain status. The practical test will be whether the co-developed processing window and toolpath strategies translate into repeatable production volumes at the Texas facility, and whether Sintavia's expertise scales beyond the initial thermal management components into other Lockheed Martin programs. The company must now execute on delivery timelines and cost targets that meet defense procurement standards, not just technical demonstrations.
