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 the form of powder or wire, as they are introduced into the laser-generated melt pool.

Multi-laser deposition head

Meltio's technology is enclosed in a compact deposition head, host of multiple lasers and capable of processing 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 metallic raw materials.

Integration ready
Transform an existing CNC or robotic platform into a hybrid manufacturing system without 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 preventative maintenance.

High power
1.2 kW laser power and optional hot wire system for faster deposition speeds.

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

Open materials platform

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

Stainless steels
Excellent strength and corrosion resistance.

Mild steels
Economical and ductile, with unrivaled workability and weldability.

Maximum strength to weight ratio and corrosion resistance.

High versatility, exceptional resistance to heat and corrosion.

Copper and Aluminium
In development

Excellent mechanical properties

Meltio's thermally compact zone process achieves exceptional mechanics, reduced 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 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 printing speed and surface roughness. Under some conditions, the surface roughness of Meltio using wire can exceed those produced with powder-based processes.
Post production
For many high-resolution printed applications little or no post-processing is required. Near-sharp shapes can be post-processed using heat, sandblasting, polishing, brushing, or machining.
