Abstract: A shot cascading apparatus for cleaning 3D printed components, generally of any surface debris, such as residue silica from the printing of the component, includes a series of vertically aligned structures, including a shot supply hopper, having a bottom regulated shot gate, for discharging through gravity of metallic shot, into a lower aligned funnel, nested within the bin of a machine base, that allows for surface cleansing of a printed component while achieving a finished product. The supply hopper has a shot gate that is adjustable, for controlling the amount of released shot, and the bottom of the funnel includes a sand separator nozzle, that separates the steel shot from the residue sand, drawing the sand back into the nozzle and conveying it by suction to a location for collection. Beneath the bin is a shot recycle pump, that returns the steel shot back into the supply hopper, for immediate reusage.
