Abstract
Abstract. This paper presents the influence of the Hot Isostatic Pressing (HIP) process on the structure and properties of the components printed by Selective Laser Melting (SLM) technology. The samples were manufactured from magnetically soft FeSi6.5 alloy powder, using different SLM printing parameters. Semi-finished products were densified in the HIP process by varying its duration and isostatic pressure value. Density, hardness, and microstructure were tested on the printed parts both before and after HIP densification. The application of the hot isostatic pressure densification process indicates a change in its final properties concerning the feedstock components. The influence of variable SLM printing parameters of semi-finished parts on the production quality and properties after the HIP process was also observed.
