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

Electron-optical in-situ metrology for electron beam powder bed fusion: calibration and validation [PDF]
Measurement Science and Technology, 2021 AbstractA major advantage of metal additive manufacturing is the possibility for tool-free production of complex shaped parts. Currently, the geometrical and dimensional accuracy of these parts can only be reliably controlled by time and cost intensive post-process inspection, e.g. using x-ray computed tomography (XCT).

Journal of Manufacturing and Materials ProcessingElectron beam–powder bed fusion (PBF-EB) is an additive manufacturing process that utilizes an electron beam as the heat source to enable material fusion. However, the use of a charge-carrying heat source can sometimes result in sudden powder explosions,
