Fraunhofer ILT and Etxetar partner to scale LMD and EHLA for aviation and Euro 7 coatings

Fraunhofer ILT and Etxetar have signed a memorandum of understanding to jointly advance industrial adoption of Laser Metal Deposition (LMD) and extreme high-speed laser material deposition (EHLA). The partnership combines Fraunhofer ILT’s process development and digital optimization expertise-including in-process geometry measurement and AI-driven parameter adjustment from its AI-SLAM project-with Etxetar’s machine-tool engineering and application experience in turbine blade repair, railway axle restoration, and gear component refurbishment. The collaboration targets aviation, coating technologies, and other industrial sectors where regulation, durability requirements, and cost pressures are converging.
For Etxetar, this deal is a strategic move to move beyond its established repair-and-refurbishment niche into scalable production coating, particularly for the automotive brake disc market driven by Europe’s Euro 7 emissions framework. Euro 7 now addresses non-exhaust brake particle emissions, creating a regulatory pull for EHLA-based coatings that Fraunhofer ILT’s Dr. Thomas Schopphoven expects to propagate to China, India, and Japan. This fits a recurring pattern in AM adoption: regulation creates a clear technical need, which then opens a window for laser-based processes to displace conventional coating methods. For Fraunhofer ILT, the partnership provides an industrial engineering partner with a customer base in aviation and heavy machinery, accelerating the transfer of its lab-developed LMD and EHLA know-how into certified, repeatable production workflows. The aviation focus-blisk and turbine blade repair-remains the highest-qualification-bar application for DED, where precision and process control are non-negotiable.
The practical significance here is that LMD and EHLA are moving from process-development curiosity to regulation-backed production necessity. Etxetar must now demonstrate that its EHLA coating lines can meet Euro 7 cycle-life and wear standards at automotive scale, while Fraunhofer ILT’s AI-SLAM system needs to prove it can reduce manual intervention enough to make the economics work for high-volume brake disc coating. For buyers evaluating DED for repair or coating, this partnership signals that the technology stack-machine, process monitoring, and adaptive control-is becoming an integrated package rather than a collection of point solutions. The next milestone to watch is whether Etxetar can convert its aviation repair references into certified production contracts for Euro 7 components.
