Selective Laser Melting (SLM)

Selective laser melting (SLM), also called direct metal laser melting (DMLM), is a type of metal additive manufacturing or 3D printing. Often, the terms SLM and direct metal laser sintering (DMLS) are used interchangeably.

SLM Part Strength

SLM parts are more robust and denser than investment cast metal parts, and they can help you get to market first with faster turnaround times.

How Selective Laser Melting 3D Printing Works

SLM is very similar to DMLS, and both processes are covered under the metal powder bed fusion umbrella. As demonstrated in the image above, the laser melts the powder together, layer-by-layer, until the model is complete.

On a molecular level, the powder is melted together, resulting in a homogeneous part. Most commonly the printing materials are “pure” materials, for example, titanium. However, alloys are also used.

Although the powder bed lends support to the print while printing, often, because of the weight of the material, SLM requires support structures to be added to any overhanging features.

Why Use SLM?

SLM is one of the most exciting 3D printing technologies available today and is utilized both for rapid prototyping and mass production. The range of metal alloys available is fairly extensive. The end result has properties equivalent to those manufactured via traditional manufacturing processes.
