1. A system for washing a 3D-printed object, the system comprising:
a washing device comprising a container forming a process chamber for receiving a liquid cleaning agent and, an agitator for agitating the cleaning agent, wherein the container further includes an inlet into the process chamber; and a
and at least one workpiece that comprises the 3D-printed object, wherein the workpiece further comprises at least one support structure supporting the 3D-printed object and a base supporting the support structure, wherein the base, in a mating relationship with the inlet, closes the inlet and forms a restraint preventing the workpiece from passing through the inlet in a situation in which the workpiece is placed with the 3D-printed object located within the process chamber, wherein the 3D-printed object and the support structure comprise the same light hardenable resin, and wherein the base forms a perforated build platform retaining the support structure.
