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.
