Abstract: A system for forming an abrasive article is presented. The system includes a workspace and an abrasive material dispenser that deposits a layer of abrasive material onto the workspace. The system also includes a leveler that levels a surface of abrasive material on the workspace. The system also includes a binder jet printer that dispenses a liquid binder onto the layer of abrasive material. The workspace is on a moving surface that moves the workspace between a dispensing position under the dispenser, a leveling position under the leveler, and a printing position, under the printer.

Abstract: An abrasive wheel maker apparatus comprising: a wheel substrate (710) having a dispensing surface; an abrasive material dispenser (720) to dispose a binder precursor onto a circular section of the dispensing surface and to dispose a plurality of abrasive particles at least partially within the binder precursor; and a rotation device (700) to rotate the dispensing surface relative to the abrasive material dispenser (720) to form a continuous single layer bonded abrasive wheel.
