In the article Metal 3D Printing Solutions to Overcome Shortfalls in Defense Logistics, Meltio presents its directed energy deposition (DED) technology as a solution to supply chain disruptions in defense and other demanding sectors by enabling on-site, on-demand production of metal parts where traditional manufacturing cannot reach.
Meltio’s DED print head is integrated into Snowbird’s SAMM Tech platform, a containerized solution combining additive and subtractive manufacturing. The system uses standard welding wire, requires no post-processing such as heat treatment, and operates with inert compressed gases like argon to enhance safety and usability in various environments.
The article highlights a recent deployment aboard the USS Somerset during Exercise Rim of the Pacific 2024. Engineers from the Consortium for Advanced Manufacturing Research and Education (CAMRE) used a Meltio hybrid 3D printer to address a real-world failure of a reverse osmosis pump. The system produced a replacement component on board, enabling water system repair ahead of traditional supply timelines.
According to team members, the ability to print and finish parts on a single machine reduced time, eliminated reliance on external replacements, and provided replicable results. Parts produced with the system require no heat treatment and can match or exceed the strength of original components.
The article also references the Department of Defense’s 2021 Additive Manufacturing Strategy, which supports wider adoption of such technologies to improve readiness and modernization.
Key benefits detailed in the article include:
- Use of common welding wire in multiple alloys
- No need for powders or external post-processing
- Faster equipment repair and part replacement directly at the point of need, reducing reliance on external logistics
- Integration of feature addition, enabling targeted upgrades
- Applicability in defense, aerospace, mining, and energy sectors
The SAMM Tech platform allows for the repair and enhancement of existing parts, combining additive and subtractive methods in one workflow. Meltio’s DED technology supports operational efficiency by minimizing material waste, extending component life, and enabling customized solutions in remote or high-risk environments.
