Some aspects influencing production of porous structures with complex shapes of cells

The article deals with some aspects influencing Direct Metal Laser Sintering (DMLS) technology. The 3D printing method is used in production of metal parts, at which a product is built layer by layer. The main advantage of this method is the ability to produce parts which have a very complex geometry and which are produced by classical conventional methods in very complicated way. To be 3D printing technology included in the industrial production of the real components it is required to achieve high mechanical properties of produced parts. The final properties of produced parts are strongly dependent on each individual laser produced track and layer. Impacts of individual factors on the quality of product are described in the article. There is also presented preliminary study related with the modelling and manufacturing of porous structures. It comes to geometrically defined structure with complex shapes that allows weight reduction with sufficient toughness. © Springer International Publishing AG 2017.
