Abstract Scope |
Currently, manual depowdering of BJAM parts is labor intensive and prohibits the technology’s wide-spread use in the industry. Automation of binder jet depowdering consists of controlling a robot to grip and lift a part. In this study, the drag of the end effectors, or fingers, utilized in the automation of binder jet depowdering when moving through a bed of powder will be evaluated. Findings in the literature will be discussed which includes a range of analysis understanding powder flowability and drag through granular mediums. The objective of this presentation is to correlate drag forces from experimental data and theoretical data with three fingers of varying diameters while the cross-sectional area is controlled. These new findings from experimental and theoretical drag forces are explored to develop predictability on optimizing future finger designs for various powders and preventing part deformation to aid in the automation process in BJAM and understand granular physics. |
