How Metal 3D Printing works (SLM)

Thin layers of fine metal powder are evenly distributed using a coating mechanism onto a build platform. Then, each 2D slice of the part geometry is created by selectively melting the powder. This is accomplished with a high-power laser beam with hundreds of watts. The laser energy is intense enough to permit full melting of the particles to form solid metal. This takes place inside a chamber containing a tightly controlled atmosphere of inert gas. The process is repeated layer after layer until the part is complete.


Metal 3D Printing Process Limitations


Heat Treatment

The printing process often includes a heat treatment step to make sure the part doesn’t deform of break shortly after printing. This can dramatically increase manufacturing times.

Materials

New Material parameters development is a lengthy process (at least 12 months) : Trial&error based, pricy mechanical testing

Hardware: Ultrasonics Vibrations, an Analogy

Here’s an analogy to understand our hardware breakthrough: While a conventional metal 3D printer works like a regular oven, and ‘cooks’ a part from the outside in, leading to thermal imbalances, our printer works like a microwave oven, where the part solidifies much more evenly, and thus is much more structurally sound without the need for heat treatment.
