SLM (selective laser melting) – is a 3D printing technology that uses metal powders as a working material. The metal powder is melted with a laser beam to give it a shape. The three-dimensional model is created by melting (sintering) successive layers of the model one by one. The whole process takes place in a special protective atmosphere for working space safety. Thanks to this, in the chamber, where the metal is sintered, it does not react with the oxygen.
Selective sintering of metal models saves time when producing short series or prototype models. Elements that would have been created for weeks by traditional methods can be completed in just hours or days.
