Sažetak
Numerous factors affect the quality of selective laser melted components, however based on previous studies it was found that scanning speed and laser power have the greatest influence of all process parameters. Moreover, at different energy densities during selective laser melting (SLM) of Ti6Al4V alloy, different mechanical properties and product quality can be achieved. This phenomenon generates high interest in customizing mechanical properties of SLM-ed components. In this study, the range of process parameters is selected based on previous research findings to produce test specimens with the lowest possible porosity. In this way, the negative effect of high porosity values on monotonic and cyclic elastoplastic behavior can be minimized. The aim of this research in its early stage is to investigate the influence of laser power and scanning speed on the surface roughness and porosity of SLM-ed Ti6Al4V alloy. Based on top surface roughness measurements on the cubic specimens, it was found that average surface roughness increases with the scanning speed and reaches its maximum value at scanning speed of 1500 mm/s at all observed laser power levels. Variability of the average surface roughness data and standard deviation reaches its minimum value at the scanning speed of 1000 mm/s for all laser power levels. Nearly full material density can be achieved using the laser power of 250 W and scanning speed of 1250 mm/s. The results of this research study can be useful in the early stage of selecting appropriate SLM process parameters to achieve desired product quality in engineering applications
