Meltio :: Wire-Laser Metal Additive Manufacturing

Meltio is a Spanish company founded in 2019 in Linares that has rapidly become a global leader in affordable wire-laser metal additive manufacturing. The firm specializes in Directed Energy Deposition (DED) technology that uses standard commodity welding wire as feedstock, delivering high-density parts with near-net-shape accuracy and zero material waste. Meltio’s solutions target industries needing on-demand production, repair, and large-format capabilities where traditional casting, machining, or powder-based systems fall short.

The company’s robot-based products form the core of its offering for industrial-scale applications. The Meltio Engine Robot Integration is a compact laser deposition head that mounts on any major industrial robot arm, transforming it into a powerful hybrid manufacturing system for large parts, complex geometries, cladding, feature addition, and in-situ repair. This kit supports 24/7 autonomous operation and handles a wide range of metals using affordable wire.

Complementing this is the Meltio Robot Cell, a complete turnkey robotic cell that includes the robot, safety enclosure, and Meltio Engine integration for ready-to-deploy metal 3D printing. Together these platforms enable manufacturers to produce or repair oversized components—such as impellers, molds, turbine blades, defense parts, and aerospace structures—without tooling or long supply-chain delays. Meltio also offers the standalone Meltio M600 industrial printer and CNC integration kits, but its robotic solutions stand out for their flexibility and ability to handle parts far larger than conventional printers.

With more than 650 systems installed worldwide and over 120 employees, Meltio emphasizes reliability, ISO 9001:2015 and 14001:2015 certification, and an open material ecosystem. The technology is already deployed across aerospace, defense, automotive, oil & gas, marine, and mining sectors, often reducing lead times from weeks to days while cutting costs and material usage.
