The 3D printed cubic bulk specimens (10x10x10 mm) were fabricated by Selective Laser Melting (SLM) additive manufacturing (AM) technology from TiAl6V4 powder, using different layer thickness (from 40 to 60 μm), for investigation of the influence of layer thickness on microstructure of SLM-fabricated TiAl6V4.

The paper studies the atomization of Al-based alloy AlSi12 in gas jet. Air was used as a spraying gas. The size and shape of powder particles were studied by using scanning electron microscopy and optical granulomorphometer. The obtained powder was used in selective laser melting.
