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).

Abstract: The present invention relates to a kit of parts comprising a dental mill blank comprising a porous zirconia material and a colouring solution for colouring the porous zirconia material. The porous zirconia material comprises Zr oxide calculated as ZrO2: from 80 to 97 wt.-%, Al oxide calculated as Al2O3: from 0 to 0.15 wt.-%, Y oxide calculated as Y2O3: from 1 to 10 wt.-%, Bi oxide calculated as Bi2O3: from 0.01 to 0.2 wt.-%, the porous zirconia material not comprising Fe calculated as Fe2O3 in an amount of more than 0.01 wt.-%, wt.-% with respect to the weight of the porous zirconia material. The colouring solution comprises solvent(s), colouring agent(s) comprising metal ions selected from Tb, Er, Pr, Mn or combinations thereof, the solution not comprising Fe ions in an amount of more than 0.01 wt.-%, the solution not comprising Bi ions in an amount of more than 0.01 wt.-%, wt.-% with respect to the weight of the colouring solution. The invention also relates to a process of producing a dental restoration, the process comprising the steps: providing a dental mill blank comprising a porous zirconia material as described in any of the preceding claims, machining an article out of the porous zirconia material, the article having the shape of a dental restoration with an outer and inner surface, providing a colouring solution as described in any of the preceding claims, applying the colouring solution to at least portions of the surface of the article having the shape of a dental restoration.
