Direct-metal energy beam SFF processes typically produce layers by scanning the
contours and then filling in the area within the contour. Process parameters used to solidify
contours are often different from those for fill areas. It is to be expected, therefore, that the
contour and fill area regions will have different microstructures. This can have important
ramifications for thin walled components such as biomedical implants whose slices have very
little fill area. This paper characterizes the metallurgical differences in contour and fill areas in
titanium components produced via Electron Beam Melting. The implications of these properties
for thin walled components are described.Mechanical Engineerin
