The research within this study focuses on analyzing the surface characteristics of samples obtained through laser sintering of MS1 steel powder without subsequent reinforcement (as built). Test samples are produced by an EOSINT M280 machine in a nitrogen environment using the method of Direct Metal Laser Sintering (DMLS). Surface layer characteristics in terms of cavitation resistance were examined using the ultrasonic vibration method according to the ASTM G32 standard. Based on the microstructure of the samples obtained using Scanning Electron Microscopy (SEM), the experiment duration was estimated. The morphology and microstructure of the samples were then examined during and after the experiment, also using SEM. The mass
loss of the samples over time was measured, to calculate the cavitation rate. This research aimed to analyze the potential future applications of laser-sintered MS1 steel powder in the fabrication of machine elements and parts operating under cavitation erosion co...nditions, due to a series of advantages of the additive manufacturing technology compared to conventional technologies.
