PIM or FFF are net-shape processes that present the advantage of manufacturing intricate geometries very close to the final goal, minimizing the need of finishing or machining processes. The powders, carefully adjusted in terms of particle size and distribution, are mixed with organic binders to provide plasticity and softness for the shaping stage. The obtained material is the so-called feedstock, which is then injected into the mould in the injection machine (PIM) or printed after the filament production (FFF). The green part is then removed from the mould or the printer and the debinding process starts. The obtained brown parts show dimensionally stable forms after the organic binder decomposition and, finally, they are sintered densely in a furnace. Both approaches are complementary and share most of the production stages, enabling the high degree of automatization and covering from low production volume to mass production of highly complex shapes.
