Example of mesh structure showing geometric freedom manufactured using Selective Laser Melting (SLM) technology
Selective Laser Melting (SLM) is an additive manufacturing process that can be used for many different applications.
The SLM process starts by numerically slicing a 3D CAD model into a number of finite layers. For each sliced layer a laser scan path is calculated which defines both the boundary contour and some form of fill sequence, often a raster pattern. Each layer is then sequentially recreated by depositing powder layers, one on top of the other, and melting their surface by scanning a laser beam.
The powder is spread uniformly by a wiper. A high power-density fibre laser with a 40µm beam spot size fully melts the pre-deposited powder layer. The melted particles fuse and solidify to form a layer of the component.
