1. A method for the production and/or treatment of a three-dimensional printed object with a printing material which is dispensed at a target position in the form of discrete three-dimensional printing material elements, wherein a metering device has a metering head and is moved by a transport device to a metering tool provided in a holder; the metering tool is installed in the metering head; the metering device together with the installed metering tool is moved to at least one reservoir in which a supply of printing material is kept; printing material is picked up from that at least one reservoir by means of the metering device; the metering device is moved by the transport device to a target position defined in all three spatial dimensions; and, at that target position, a metered quantity of printing material is applied by means of the metering device to a substrate or to a three-dimensional printed object arranged thereon or being constructed thereon, in order to create one of the printing material elements, the creation of one of the printing material elements being repeated until the three-dimensional printed object has been fully constructed and/or treated.
