Definitions

  • Additive layering methods refer to processes in which geometric data is determined using a virtual model of a component or component area to be manufactured, which is broken down into layer data (so-called “slicing”). Depending on the geometry of the model, an exposure or irradiation strategy is determined according to which the selective hardening of a material is to take place. In the layer construction process, the desired material is then deposited in layers and selectively scanned and solidified using an energy beam in order to build up the component layer by layer. Various irradiation parameters such as the energy beam power and the exposure speed of an energy beam to be used for solidification are important for the resulting microstructure. The arrangement of so-called scan lines is also important.
  • the scan lines which can also be referred to as individual tracks, melting tracks or exposure vectors, define the paths along which the at least one energy beam scans and melts the material and can generally run linearly or non-linearly.
