This study includes experimental research conducted to produce lattice structures and to examine their mechanical properties by taking advantage of the design freedom provided by additive manufacturing. Much of the existing literature involvesmainly process parameters on mechanical behaviors. Thus, more lattice geometry studies are needed. In this study, diferentlattice structures designed according to the unit cell types selected through the SpaceClaim program were produced usingAlSi10Mg powder material with the laser powder bed fusion (LPBF) method the metal additive manufacturing productionmethods. Cell sizes, Maxwell criterion, relative densities, and mechanical behaviors under semi-static compression forcewere investigated. It was concluded that with increasing relative density, the strength increased, and the structures withstress-dominating were more resistant than those with bending-dominating strength. It was determined that the mechanicalproperties of lattices depended on unit cell design and LPBF process parameters. The C1 and C2 coefcients of latticesproduced by the LPBF process included in the Gibson and Ashby equation were determined.
