Powder bed fusion (PBF) is an additive manufacturing process and works on the same basic principle in that parts are formed through adding material rather than subtracting it through conventional forming operations such as milling. The PBF process begins with the creation of a 3D CAD model, which is numerically 'sliced' into several discrete layers.
