3D printer for the additive manufacture of a component, and printing method

A 3D printer for additive manufacturing of a multilayer component, comprising:

• a conveyer belt that is made of a radiation permeable material, the conveyer belt having a first side and a second side opposing the first side;
• at least first and second separate dispensers for dispensing a first raw material and a second raw material onto the first side of the conveyer belt, the first dispenser being associated with the first raw material, the second dispenser being associated with the second raw material;
• a manufacturing unit having a radiation source arranged to radiate energy toward the second side of the conveyer belt and through the conveyer belt, the radiation source for curing, by use of the energy transferred through the conveyer belt, the first raw material and the second raw material to create new layers of the multilayer component;
• and
• at least first and second recovery devices, the first recovery device for selectively recovering, from above the first side of the conveyer belt and laterally adjacent to the manufacturing unit, the first raw material which is not consumed when a new layer is added to the multilayer component and for returning the first raw material to the first dispenser, the second recovery device for selectively recovering, from above the first side of the conveyer belt and laterally adjacent to the manufacturing unit, the second raw material which is not consumed when a new layer is added to the multilayer component and for returning the second raw material to the second dispenser;
• and wherein the conveyor belt transports the first and second raw materials from the first and second dispensers to the manufacturing unit and then to the first and second recovery devices.
