A galactic extrusion manufacturing (GEM) system for performing an extrusion process includes an extruder assembly for extruding building material during the extrusion process, and a connection system including a robotic arm-tether-crimper for attachment of the GEM system to space bound vehicles and/or structures in space or on orbit. The extrusion assembly includes an extruder head outfitted with multiple different heads for shaping the building material during the extrusion process, at least one power cartridge, and at least one building material cartridge containing the building material, wherein the power cartridge and the building material cartridge are removable and replaceable. Also provided are a building material cartridge for use with a GEM system or a dispensing control unit (DCU) to perform an extrusion process, and a smart extrusion system including a building material cartridge and a DCU.

A method for the dry filtration of a gas flow carrying foreign objects, a filter device for cleaning off waste gas resulting from additive manufacturing technologies, comprises feeding a raw gas flow containing foreign objects into a raw gas space of a filter unit having at least one filter surface separating a raw gas side from a clean gas side; feeding oxidant to a reaction region located on the raw gas side of the filter surface downstream of the filter surface; such that foreign objects contained in material cleaned off from the filter surface and/or in the raw gas flow react with the oxidant in the reaction region to form oxide-containing foreign objects.

The present invention relates to an additive manufacturing system and an additive manufacturing method. The additive manufacturing system includes an operator area, a loading area, and a transportable container unit. The operator area is configured to control the manufacturing system. The loading area is configured for loading the manufacturing system. The operator area is accessible from a first side of the manufacturing system and the loading area is accessible from a second side of the manufacturing system, wherein the first side is different from the second side. The transportable container unit is insertable into the loading area. The transportable container unit includes a powder storage container and a building container. The powder storage container is configured to store powder, and the building container is configured to additively manufacture a workpiece.

A device for the stereolithographic additive manufacturing of metallic components includes a material support for a material layer of a material to be polymerized, the surface of which forms a building plane, a material container for fresh material, which opens into the building plane via a material feed opening, a build platform movable between a position flush with the building plane and a lowered position perpendicular to the building plane, a doctor blade movable between the material container and the build platform for applying the material layer on the building plane, and an exposure unit for position-selective exposure of the material layer on the build platform or on a component partially built on the build platform. The material support is exchangeably arranged in the device.

An additive manufacturing apparatus includes a build module. A feed module is configured to support a first portion of a resin support. The first portion of the resin support is supported by a feed mounting panel. A take-up module is configured to support a second portion of the resin support. The second portion of the resin support is supported by a take-up mounting panel and is positioned on an opposing side of the radiant energy device from the feed module. An adjustment assembly is configured to adjust a position of at least one of a feed mandrel within the feed module or a take-up mandrel within the take-up module.

Cover assemblies for machines are disclosed, as well as machines and methods for producing three-dimensional components by selectively solidifying a material by a beam acting on the material, including a build cylinder cover that sealingly closes an opening of the build cylinder for changing of the build cylinder, and including a process chamber cover associated with the build cylinder cover, which are detachably connected to one another via an interface, wherein the build cylinder cover and the process chamber cover are formed as a single handling unit for changing the build cylinder.
