Research on process parameters for producing of a structured material made by Selective Laser Melting technology
 Richter, Vladislav ; Koutný, Daniel (referee) ; Vrána, Radek (advisor)
Selective laser melting (SLM) is one of additive technologies which allows manufacturing of components with very complex shape. One of the examples are porous lattice structures which are used in cosmonautics or medicine due to its good mechanical properties and low weight. In this work the influence of processing conditions (laser power and laser scanning speed) on material properties and geometry of as-fabricated trusses is investigated. Wide range of laser powers (100–400 W) and laser scanning speeds (1000–10000 mm/s) were used to determine optimum process parameters. Truss size, morphology and internal porosity was investigated using optical 3D scanner and X-ray micro computer tomography (mCT). Based on executed measurements optimum processing conditions were determined to be 350 W and 3000 mm/s. It is possible to manufacture faster geometrically more precise structures with equal internal porosity due to optimization.
