| Abstract Scope |
This study compares the fabrication of IN718 alloy using bi-directional raster and stochastic spot melting techniques with the open-source FreemeltOne Electron Beam Melting (EBM) system. The research aimed to produce dense parts using both scanning strategies, employing custom python code for raster melt beam path generation and PixelMelt software for stochastic spot melting. After optimizing process parameters, 10mm builds for each scanning strategy were fabricated, and their microstructure, hardness, and density were analyzed using optical microscopy and Scanning Electron Microscopy (SEM), vickers microhardness scale, and a pycnometer. The findings reveal valuable insights into the effects of scanning strategies on the microstructure, hardness, and density of IN718 alloy components, advancing additive manufacturing knowledge. |
