Meltio technology

Laser deposition of metal

LMD is a Directed Energy Deposition (DED) process that works by precisely stacking weld beads on top of each other, in powder or wire form, as they are introduced into the laser-generated melt pool.

Multi-laser deposition head

Meltio technology is enclosed in a compact deposition head, host of multiple lasers and able to process wire and powder simultaneously.
Safe and reliable
Most of the 3D printing process is built around wire, the safest, cleanest and easiest to work with metal raw materials.
Integration ready
Transform an existing CNC or robotic platform into a hybrid manufacturing system with no inherent size constraints.
Multi material
Print double wire for hardfacing or anti-corrosion applications, or wire and powder to create new alloys on the fly.

Process stability
The metal 3D printing process is monitored in real time and compensated by process control.

Maintenance ready
Long life with excellent access to all components for preventive maintenance.
High power
1.2 kW laser power and optional hot wire system for higher deposition rates.

Extremely efficient
Wire deposition uses 100% of the material and the heat input is kept extremely low.

Open material platform

Meltio recommends printing most parts with wire, the cleanest, safest, and cheapest metal feedstock on the market. If the desired building material is not available in wire form, powder can be used.

Excellent mechanical properties

Meltio's thermally compacted zone process achieves outstanding mechanics, low thermal stress, and near isotropic properties, surpassing the properties of casting and forging materials.

Constant densification of 99.998%.
Meltio's WP-LMD produces fully dense parts with a superior microstructure. Exceed casting and forging properties and, in some cases, match the properties of the machined material.

Part density
0.6 to 1.2 mm layer height
The Meltio process allows for an exceptional balance between print speed and surface roughness. Under some conditions, the surface roughness of Meltio using wire can exceed those produced with powder-based processes.
Post production
Little or no post-processing is required for many high-resolution printed applications. Near-net shapes can be post-processed using heat, sandblasting, polishing, brushing, or machining.
