Figure 5: Examples of Ti-6Al-4V components built from powder in Figure 3(a) using the Arcam A2 EBM system in Figure 3c. (a) Solid (fully dense) cylinders built in the Z-axis (beam) direction and in the layer plane (X,Y). Rockwell Cscale hardness average is noted. (b) and (c) show open-cellular monoliths. A and B show two foam densities with A more dense than B. C shows cylindrical foam as in A. D and E are dode-thin mesh open cylinder; E has a thin solid cylinder built inside the mesh. F is a solid cylinder built in the Z-axis direction as in (a). Adapted from Murr et al. [28].
