Additive manufacturing (AM) emerges as a method based on layer-by-layer manufacturing, which is preferred in manufacturing lattice structures today. Within the scope of this study, three types of lattice samples consisting of BFCC (Body Face Centered Cubic) hybrid, BCC (Body Centered Cubic), and FCC (Face Centered Cubic) unit cells were manufactured by Electron Beam Melting (EBM) method using the Ti6Al4V powder. The porosity in the manufactured samples is lower than the designed models due to the struts thickening and the unmelted sintered powders in the structures. Compression test results showed yield strength values in BFCC hybrid, FCC, and BCC unit cells, from high to low, respectively. In addition, the FCC structure behaved as brittle, while the BCC and BFCC hybrid structures behaved as ductile. According to SEM (scanning electron microscope) examinations, thickening occurred in the columns, and the fractures occurred in the regions close to the nodal areas of the columns. Since there were both dimpled and flat (cleavage) areas on the fracture surfaces of all samples, the fracture of the lattice structures exhibited both ductile and brittle behavior.
