Abstract Scope |
Binder jetting of aluminum powder has progressively gained the interest of automotive and aerospace industries for the fabrication of lightweight products. However, the interactions between the polymeric binders and oxidative behavior of aluminum powder have not yet been extensively studied by researchers. Hence, this research focuses to understand the impact of polymeric binders on the final quality of the aluminum samples by analyzing the level of impurities and densification. Five binders were prepared to fabricate green state samples with the AlSi10Mg powder. The lowest level of impurities was obtained with the alcohol solvent-based binders while moderate to high binder residues were reported with the organic solvent and water-based binders. In addition, the highest sintered density of 95.1% was achieved using the alcohol solvent-based binder, whereas the water-based binder delivered the lowest sintered density. Therefore, this research recommends the PVP binder as the most suited binder among the considered binders. |
