Metallic fine powders are widely used in many additive manufacturing (AM) industries. To control and optimize processing methods, powders must be precisely characterized either based on grain properties or behavior of bulk powder. In this research, we will focus on powder spreadability in Selective Laser Melting (SLM) process, which is a kind of bulk powder behavior. Three metallic powders (Nickel and Aluminium alloy) are studied. Powders spreadability is determined with the GranuDrum, a rotating drum enabling to quantify the influence of cohesion, shear-thinning/thickening as well as thixotropic behavior. It allows to assess the powder spreadability without applying compressive load during the powder testing what fits with the conditions seen by powders in AM processes. These measurements are correlated to powder performance in 3D printer, where a CCD camera is used to take several snapshots of powder bed. Two different recoater wipers and two recoating speeds (30 and 160mm/s) are explored.
