Device for additive manufacturing of a component

A device for additive manufacturing of a component, including:

• a printhead configured to apply a liquid material, wherein the printhead includes a base;
• a controller configured to control the printhead to apply the liquid material;
• a magazine having multiple nozzles, which are each detachably fastenable to the printhead in a first mounting position relative to the base;
• a first reservoir configured to contain the liquid material, the first reservoir being fastenable to the base in a second mounting position relative to the base;
• a piston attached to the base and configured to eject the liquid material out of an outlet opening defined in the first reservoir;
• a retaining member movably mounted on the base and having an upper end that holds the piston, the retaining member being biased with the piston against the base;
• a separating apparatus configured to move the retaining member in a direction opposite of the biasing;
• a piston engagement device configured to engage with the piston when the first reservoir is released;
• and
• at least one actuator configured to be controlled by the controller to move the printhead and/or the magazine relative to each other so that one of the multiple nozzles is moved to the first mounting position;
• wherein the controller is configured to control the piston engagement device to grasp and remove the piston from the retaining member when the retaining member moves away from the base.
