Metal Sintering (DMLS/SLM)

What is metal sintering?

Metal sintering is a process that allows to make mechanical parts in aluminum, stainless steel AISI 316L,and other special alloys. The dust grains weld together at high temperature: layer by layer the powders are melted by the laser beam allowing the creation of resistant mechanical components, and the components are suitable for post-processing such as milling, CNC turning, heat treatments, surface treatments both aesthetic and protective.

This technique manages to form a piece that for some simple shapes may not require subsequent processing. It is used to produce materials with particular properties, which they would not have if they were created with other techniques.

Below you can see how it works:

The company’s focus is on the application of Additive Manufacturing with highly specialized 3D Laser Sintering machines for metal powders (by EOS GmbH).

It is a line of separation between present and future of industrial production: unlike conventional or subtractive production processes, additive manufacturing builds a part using a layer-by-layer process directly from a digital model, eliminating the need of molds or matrices.

The laser source that melt the metal powder, draws layer by layer the model loaded from CAD files until the desired object is obtained. The products in this way have mechanical properties comparable to products obtained by classical subtractive process with a high degree of precision. The processing uses a high-precision laser and is directed at metal dust particles to build, selectively, thin, and subsequent horizontal metal layers. Metal dust particles merge, so that the new material properly attacks to the previous level, without glue or binding liquid.
