Deposition Head:

The Patented Deposition head forms the core of our technology. It can process both wire and powder feedstock unidirectionally by combining the output of multiple laser sources. The built in Dual Wire feed system ensures excellent control over the material flow and integrated sensors let us achieve industry leading process stability. With Good Access to all wear components and Protection for the optics the system is easy to maintain and offers a long service life.

Printing Process:

Meltio’s LMD-WP Process Functions by precisely stacking weld beads on top of one another to create a 3D Structure. The weld bead is created when Filler material, in powder or wire form is introduced into the laser generated melt pool. Especially when processing wire, high deposition rates are achieved while keeping the heat affected zone, and thus thermal stresses in printed components low. The unique ability to process two wire materials in a single part, along with the capability of printing powder and wire materials at the same time makes our process ideal for the creation of highly complex components from demanding materials. However, thanks to its low cost of acquisition and material costs for single or dual wire operation, Meltio makes metal 3D Printing accessible for conventional parts as well.
After printing the component can directly undergo machining or surface treatment to create high precision fits, while for parts with lower tolerance requirements the component may be left as is.
Typical bead widths for wire correspond to 1.2x the material diameter, representing the lower wall thickness limit for wire 3D Printing. Powder Deposition can create thinner walls; however, this wastes some material as not all of the powder is captured in the meltpool. Therefore, we recommend to always use wire for large structures. The system can process standard MIG Filler materials, ensuring excellent availability and low material prices globally. Unlike other metal 3D Printing processes there are no limits to the maximum wall thickness of components.
Typical layer heights range from 0.3 to 1.2mm and can be selected depending on the required surface finish and printing time. Final Part Density and mechanical properties are comparable to forgings. Contact us for material testing data.

The software tool chain is another core component of our technology. We offer a streamlined user experience that makes the system both accessible to new users yet offers a high customizability for our research customers, with all parameters being accessible. The touchscreen on our system provides a comfortable user interface from which all printer functions can be controlled.
Meltio supplies customers with proven printing profiles for an ever-increasing material range. Further our software is updated regularly giving customers new features throughout their machine’s lifecycle. While the updating requires a brief internet connection the printer can be used completely offline.
