A system (1) for additive manufacturing of three-dimensional objects, comprising one or more working stations (21), which are provided for performing at least one working process in the additive manufacturing of three-dimensional objects, at least one freely positionable mobile storage unit (2) comprising a rack-like storage device (4) comprising at least one storage room (5) provided for storing at least one powder module (6), especially for the purpose of conveying the powder module (6) between different working stations (21) of the system (1), and at least one driverless, freely movable mobile conveying unit (3) comprising a receiving device (12) provided for receiving at least one mobile storage unit (2) for the purpose of conveying the storage unit (2) between different working stations (21) of the system (1).

A forming device for producing moulded bodies by selectively hardening powder material to form connected regions, including a process chamber having a powder inlet and a powder outlet. A powder supply apparatus is connected to the powder inlet for providing powder material to the process chamber. A powder recovery apparatus is connected to the powder outlet for receiving and recycling excess powder material from the process chamber. The powder supply and powder recovery apparatuses form a subassembly designed as an interchangeable module. The interchangeable module includes input and output connection interfaces connection-compatible with connection interfaces of the powder inlet and powder outlet. Excess powder is fed from the process chamber through the powder outlet to the powder recovery apparatus via an input interface of the interchangeable module. Powder material prepared by the powder recovery apparatus is fed to the process chamber through the powder inlet via an output interface of the interchangeable module.

The invention relates to a system and to a method for coating workpieces using a coating device, which is designed to apply a metal coating to a surface of the workpiece. According to the invention, it is provided that a plurality of coating devices, which are designed as identical coating modules, are provided and are arranged in a module group, that an input measuring station is assigned to the module group, by means of which station a surface of the face of the workpiece to be coated can be detected, that a conveying apparatus is provided, by means of which a workpiece can be supplied to one of the coating modules from the input measuring station, and that an output measuring station is assigned to the module group, by means of which station a surface of the coated face of the workpiece can be detected.

The invention relates to a coating device and to a method for metal-coating of workpieces, comprising a housing, which surrounds a working space, a retaining apparatus for retaining at least one workpiece in the working space, at least one deposition apparatus comprising a deposition nozzle for applying a metal powder to the workpiece surface to be coated, and a laser for locally melting the metal powder on the workpiece surface to form a coating, and at least one movement apparatus, by means of which the at least one deposition apparatus can be moved relative to the workpiece surface during the coating. Particularly efficient coating is made possible by at least two deposition apparatuses being arranged in the working space in the housing, which apparatuses are designed to simultaneously apply and melt metal powder.

An additive manufacturing system includes a build platform, at least one first consolidation device, and at least one second consolidation device. The at least one first consolidation device is configured to direct at least one first energy beam to a first face of a component. The first face has a first orientation. The at least one second consolidation device is configured to simultaneously direct at least one second energy beam toward a second face of the component as the first consolidation device directs the at least one first energy beam toward the first face. The second face has a second orientation different from the first orientation.

According to the invention, it is provided that the air supply is arranged in an upper region of the working space above the workpiece and the air discharge is arranged in a lower region of the working space below the workpiece. In addition, a additional suction apparatus is provided with at least one suction opening, which is arranged close to the workpiece.

The invention relates to a method and to a system for metal-coating at least one surface of a workpiece, in which before coating, a surface structure with peaks and troughs in the surface to be coated is detected by means of a measuring apparatus, the coating is carried out by means of at least one deposition apparatus, which is moved relative to the surface and applies coating material in the process, and the deposition apparatus is controlled by a control apparatus on the basis of the detected surface structure, wherein more material is applied in the region of troughs and less material is applied in the region of peaks.

A method of de-powdering green parts manufactured via binder jetting additive manufacturing. First, a bulk de-powdering operation is conducted on the green part. Next, a fine de-powdering operation is conducted on the green part. The fine de-powdering operation includes disposing the green part within a bed of shot brush de-powdering media and agitating the bed of shot brush de-powdering media to remove from at least one surface of the green part an amount of build material powder.
