In this paper, the application of additive manufacturing technology for producing the micro-lattice structure was introduced, and the effects of laser condition (laser power, scanning speed) on the strand’s geometry and mechanical properties of lattice block were investigated. When the laser power increases, the average strand’s diameter increases almost linearly. On the contrary, the diameter has a minimum value as the scanning speed increases. Also, the stress-strain curve of lattice block is sensitive to the laser conditions, which is mainly caused by the change of strand’s diameter.
