Meltio delivers metal additive manufacturing solutions, M450 and Engine, based on a new disruptive technology named Laser Metal Deposition – Wire Powder (LMD-WP).

Meltio’s LMD-WP process uses multiple fibre-coupled diode laser sources that are distributed evenly around the central axis of the head.

Meltio’s patented laser head leverages the advantages of both wire DED and powder DED within a single machine. The technology’s high laser power, multiple wire feeders, and hot wire feed options facilitate high material deposition rates while retaining the precision and resolution of a laser process. Other functions, such as metal coating, texturing, polishing, and cutting, can also be carried out without external equipment.

But, why use wire and powder simultaneously?

Powder and wire can be used at the same time to fabricate Metal Matrix Composites (MMCs), a class of materials in which one or more materials are added to metal to achieve specific property enhancements. Traditionally, MMCs are manufactured through powder metallurgy; however, this process can be expensive and time-consuming.

To bypass this, MMCs can be constructed through Meltio’s LMD-WP process at a lower cost and with shorter lead times. Meltio’s approach will also enhance the mechanical properties of the MMCs, Dr Yash Bandari, product manager in Meltio’s Additive Manufacturing Group said:

One example of where the process has been effective in this way is the addition of Titanium Carbide (TiC) as an alloying element in the form of powder to a melt pool of Ti64. This titanium alloy is well-known for its low density, high strength, and excellent corrosion resistance. Through the LMD-WP process, the addition of TiC significantly improves the wear resistance of Ti64, which subsequently becomes an MMC.”

Any material available in the form of a welding wire or powder can be used with Meltio’s LMD-WP technology. End products have subsequently been used within the aerospace, automotive, oil and gas, medical and education/research sectors for various applications.
