This work studied the preparation of starting powder mixture influenced by milling time and its effect on the particle morphology (especially the shape) and, consequently, density and compression properties of in situ Ti-TiB composite materials produced by selective laser melting (SLM) technology. Starting powder composite system was prepared by mixing 95 wt% commercially pure titanium (CP-Ti) and 5 wt% titanium diboride (TiB2) powders and subsequently milled for two different times (i.e. 2 h and 4 h). The milled powder mixtures after 2 h and 4 h show nearly spherical and irregular shape, respectively.
