Columns with regular octet lattice microstructure have been manufactured by electron beam
melting of Ti-6Al-4V powders. Each column comprised sixteen cells in the axial direction and
three cells in the transverse direction and was manufactured in four different nominal
slenderness for the struts. The columns were destructively tested both in tension and in
compression, and both their macroscopic stiffness and strength were measured. The
experimental results showed large discrepancies from the numerical and analytical …
