3D printer for additive manufacturing of a multilayer component, printing method and component

A method for additive manufacturing of a three-dimensional multilayer component, the method comprising:

• applying, by a first dispenser, a layer of a first raw material to a work surface, the first dispenser moving laterally across the work surface, wherein a layer thickness of the first raw material corresponds at least to a desired layer thickness of a layer to be added to the component;
• bringing the layer of the first raw material into contact with a surface of the component to be coated on the work surface and structurally curing a portion of the first raw material to form a new structured layer of the component;
• lifting the component comprising the new layer off the work surface;
• removing, by a first recovering device, a remaining first raw material from the work surface, the first recovering device moving laterally across the work surface and returning the first raw material to the first dispenser;
• repeating the aforementioned method steps with a second raw material and a second dispenser, wherein a second recovering device is provided so that the first and second raw materials are selectively returnable to a corresponding dispenser;
• removing, by moving a cleaning device laterally along the surface of the component, excess first raw material or excess second raw material from the surface of the component;
• and
• returning, by an associated return device, the excess first raw material or the excess second raw material to the corresponding dispenser.
