1. A method for additively manufacturing a three-dimensional, multilayer component, comprising:
applying a layer of a first raw material to a conveyor belt by use of a first dispenser, wherein a thickness of the applied layer of the first raw material corresponds at least to the desired layer thickness of a layer to be added to the component;
transporting the conveyor belt with the layer of the first raw material onto a work surface:
bringing the layer of the first raw material on the work surface into contact with a surface of the component to be coated, and structurally hardening a portion of the first raw material to form a new structured layer of the component;
lifting the component having the new structured layer off the work surface;
transporting the remaining first raw material on the conveyor belt to a first recovery device;
removing the remaining first raw material from the conveyor belt by use of the first recovery device, and returning the remaining first raw material to the first dispenser,
repeating the aforementioned process steps with a second raw material, a second dispenser, and a second recovery device, wherein the second recovery device is provided so that the first raw material and the second raw material can be selectively returned, respectively, to the corresponding first dispenser and corresponding second dispenser.
