Device and method for additive manufacturing of a component

A device for additive manufacturing of a component, comprising:

• a material dispensing unit for depositing a building material and an actuator assembly which is designed to move the material dispensing unit over a work surface in order to deposit the building material layer by layer in predetermined print paths, and
• at least one first guide leg which is designed to shape a first surface of the one or more layers of building material deposited by the material dispensing unit, wherein the at least one first guide leg is movable, driven by an actuator, in at least one translational degree of freedom (x, y, z) and/or rotational degree of freedom (dx, dy, dz) relative to the material dispensing unit,
• wherein the device has a cleaning assembly with at least one cleaning portion associated with the at least one first guide leg, wherein in at least one relative position of the at least one first guide leg relative to the material dispensing unit, the cleaning portion is arranged at least in portions in cleaning contact with the associated guide leg, in such a way that during a movement relative to the material dispensing unit, the at least one first guide leg is capable of stripping off building material residues on the cleaning portion, which is in cleaning contact at least in portions.
