Abstract: A method for the additive manufacturing of an item includes a step of solidifying a construction material, modifying the distribution, and solidifying the construction material. In the step of solidifying the construction material, the material is solidified in order to form at least one wall element which delimits at least one internal space. The item is a three-dimensional object formed by selective solidification of a resin-based construction material which includes at least one additive. In the step of modifying the distribution, the distribution is modified by locally increasing the concentration of the additive in the liquid construction material in the at least one delimited internal space. In the final step of solidifying the construction material, the construction material is solidified in the at least one internal space.

Abstract: A method for additive manufacturing of an item includes a first solidification step and a second solidification step. In the first solidification step, at least one structure section having a first degree of solidification is formed. The at least one structure section delimits at least one interior accommodating a liquid construction material. The item is a three-dimensional object having a resin-based construction material which is liquid in a base state and is solidifiable. In the second solidification step a deformation section is formed. The deformation section has a second degree of solidification that is different from the first degree of solidification. The deformation section is formed from the liquid construction material accommodated in the interior.

Abstract: A method for additive manufacturing of a three-dimensional object includes successively exposing a construction material having at least one UV-curable component by UV radiation to form a green body and subjecting the green body to thermal energy, where at least one component of the construction material thermally cures to form the three-dimensional object upon exceeding of a curing temperature. The successively exposing by the UV radiation to form the green body is controlled such that at least in sections the curing temperature of the at least one component is not significantly exceeded.

Abstract: A handling device for a manufacturing environment includes a manufacturing apparatus for additive manufacturing of an object, a robot device, a transport device, where the robot device is configured to interact with at least one component of the manufacturing apparatus, and a coupling device which is configured to couple the robot device detachably to the transport device. The transport device is configured to transport the robot device to at least one workstation and to uncouple the robot device from the transport device by the coupling device.
