  3D printing is an increasingly widespread manufacturing process. With the development of machines and materials, the technology is becoming more accessible and easier to use. However, the technology's specificities mean that it requires knowledge of manufacturing technology. In some cases, it is necessary to solidify the freshly deposited layers as soon as possible in the event of large overhangs. This can be achieved by active cooling, which in turn can affect the material properties of the part. This research investigates the effects of active cooling during production.

  Nowadays in the automotive industry both production and service, requires accurate lifetime calculations. Today we have big amount of theoretical background and nowadays the importancy of technical and industrial databases become more and more important. By materials scientific and fracture mechanics aspects are well covered, but the remaining stresses which are present in every step of production, we can not clearly identify the origin of them. There are different paralell methods to mesure them, but the application of different methods are depending on the engineers, and their expreiences at the company. This part of the analysis is not standardised yet, so there are differences even in the same company.
