Abstract

A system (1) for washing a 3D-printed object (4). The system (1) has a washing device (2) and a workpiece (3) that includes the 3D-printed object (4). The washing device (2) has a container (7) that forms a process chamber (8) for receiving a liquid cleaning agent (9), and the container (7) has an inlet (10) into the process chamber (8). The workpiece (3) further has a support structure (6) that supports the 3D-printed object (4) and a base (5) supporting the support structure (6). The base (5), in a mating relationship with the inlet (10), forms a restraint preventing the workpiece (3) from passing through the inlet (10) in a situation in which the workpiece (3) is placed with the 3D-printed object (4) located within the process chamber (8).
