Abstract
Binder Jetting Process is an Additive Manufacturing technique (AM) in which a liquid binder is employed for establishing the initial strength and fabricating the geometry of components. In this process, the delivery of the binding agent is accomplished through a drop-on-demand (DOD) printhead by deposition of picoliter-sized droplets of the liquid binder. The velocity of the droplets impinging the powder bed surface might have significant effect on droplet spreading and absorption dynamics, which can be manifested in quality and integrity of the fabricated parts. In the present study, the effect of the printing speed on dimensional accuracy and equilibrium saturation level of printed samples is experimentally investigated and the observed trends are discussed in detail.
