Abstract:
Spreading uniform and dense layers is of paramount importance to creating high-quality components using powder bed fusion additive manufacturing (PBF AM). Blade-like tools are often employed for spreading powder metal feedstocks, especially in laser powder bed fusion (LPBF) and electron beam melting (EBM), where powders are characterized by a D50𝑉 of 30 ÎĽm or greater. Along with variations in boundary conditions introduced by the layer-wise geometry and surface topography of the printed componen...     »
