production time is a function of the small laser spot size, laser travel speed at 50-100 mm/s, laser power, conductivity of bed and process settings such as step over (1/2 beam width), heat and cool down periods. Therefore, sand mould pattern production by DLSS has a relatively low deposition rate 2,500
