An end effector for a vacuum system is disclosed. In various embodiments, the end effector includes a central duct having a first end configured for connection to a vacuum source and a second end defining a central duct inlet; a base member proximate the second end of the central duct; and a plurality of passages extending from an outer surface of the base member to an inner surface of the central duct, the plurality of passages characterized by a passage axis having an axial vector component.

A performance of a die is improved. An injection hole IH, a nozzle NZa and a nozzle NZb are formed in a center member DIa of a die DI to extend from an extrusion surface ES to an injection surface IS. A heat source HT and a plurality of heat insulating layers HI1 are arranged inside the center member DIa. One of the plurality of heat insulating layers HI1 is adjacent to the nozzle Nzb and is closer to the extrusion surface ES than the heat source HT. The other of the plurality of heat insulating layers HI1 extends in a direction from the extrusion surface ES toward the injection surface IS at a position being farther from the nozzle NZb than the heat source HT.

Method and plant for recovery of a processed, powdered structural material in a plant for manufacturing a three-dimensional component by selective solidification of the structural material by a beam directed onto the structural material, in which, in a construction station which includes a process chamber, the component is manufactured on a substrate plate in a construction module by layered hardening of the structural material and/or in which, in an unpacking station which includes an unpacking chamber, the component manufactured in the construction module is removed from the construction module, and the processed, non-hardened structural material is removed from the component, in which the processed structural material is collected in a collecting device by a recovery device and provided for further feeding into the process chamber for manufacturing further components, wherein the recovery device includes at least one cartridge filled with the processed structural material collected in the application device.

A 3D printing cleaning module comprises an extraction gate at a lateral wall of a housing; and a platform within the housing to support a build bed including 3D printed parts and un-solidified build material. The platform is tilted or tiltable with respect to a horizontal plane towards the extraction gate to enable 3D printed parts on the platform to be removable through the extraction gate. The module comprises a cleaning engine to remove at least part of the un-solidified build material from the housing, a vibrating mechanism to vibrate the platform; and a controller. The controller is to control the cleaning engine to execute a cleaning operation by removing un-solidified build material from the housing, to cause the part ejection gate to open upon completion of the cleaning operation, and to cause the vibrating mechanism to vibrate the platform when the part extraction gate is in the open position.
