Dimensional Accuracy of Electron Beam Powder Bed Fusion with Ti-6Al-4V

Designs, 2023
While much of additive manufacturing (AM) research is focused on microstructure, material properties, and defects, there is much less research in regards to understanding how well the part coming out of the machine matches the 3D model it is based on, as
