Meltio showcases defense uses for wire-laser DED tech

Meltio, a Spanish company specializing in wire-laser Directed Energy Deposition (DED) Additive Manufacturing, is revolutionizing maintenance and repair in the defense sector. Traditional supply chains struggle to provide replacement parts for legacy military components, leading to long delays and high costs. Additive Manufacturing, by contrast, enables on-demand, on-site production even before a conventional order would be processed.
Staff Sgt Jordan Blake of the Marine Innovation Unit emphasized the speed advantage: with Meltio’s tech, parts can be printed and ready within days. This minimizes downtime and increases operational readiness.
Meltio’s DED systems, such as the M600 metal AM machine and robotic/CNC kits, allow the production of complex components with minimal redesign. Examples include a stainless steel diffuser rebuilt to enhance performance and durability, and eductors, reimagined in 316L stainless steel for better wear resistance. Closed impellers for fire protection systems were also reconstructed using a custom radial build strategy.
Meltio’s approach not only replicates critical parts but often improves them, enhancing mechanical properties and eliminating redundant features. This offers the defense sector a faster, smarter, and more resilient solution for maintaining essential hardware.
