A connecting device for receiving a cartridge container and for positioning at a connection point in an installation for producing three-dimensional components by successively solidifying layers of a powdered building material, having a housing, having a cartridge receiver which is provided at the housing and to which the cartridge container can be fastened, having a connection side on the housing opposite the cartridge receiver, which connection side has a passage for delivering powdered building material from the cartridge container or for feeding powdered building material into the cartridge container, having a closure member which is provided between the cartridge receiver and the connection side and by which the passage can be activated for opening and closing the passage.

Embodiments are directed to nozzles for three-dimensional printing and related assemblies and methods. An example method includes, on a first side of a material, forming a hole into the material to define an at least partially conical inner conduit extending at least partially through the material, and, on a second side of the material, forming a through-hole into the material to define an exit orifice of the nozzle, the exit orifice connecting with the at least partially conical inner conduit to define a fluid pathway through the nozzle.

A method for the application of hydrous mineral binder compositions which contain fibres. An aqueous accelerator is mixed with the aqueous binder composition in a mixer shortly before the application. The method is very robust and makes it possible to quickly produce even large moulded bodies having a uniform surface and very good strength development properties.

An example technique includes extruding, by a tow deposition device, on a tow-by-tow basis, respective impregnated tows of a plurality of respective impregnated tows to form a layer of material on a major surface of a substrate. Each respective impregnated tow includes at least one ceramic fiber and a curable resin coating the at least one ceramic fiber. The example technique includes curing the curable resin to form a cured composite component. An example system includes a tow deposition device, an energy source, and a computing device. The computing device is configured to control the tow deposition device to extrude, on a tow-by-tow basis, respective impregnated tows of a plurality of respective impregnated tows to form a layer of material, and is configured to control the energy source to cure the curable resin to form a cured composite component.

An additive manufacturing system including a two-dimensional energy patterning system for imaging a powder bed is disclosed. The two-dimensional energy patterning system may be used to control the rate of cooling experienced by each successive additive layer. Accordingly, the system may be used to heat treat the various additive layers.

Devices, systems, and methods are directed to binder jetting for forming three-dimensional parts having controlled, macroscopically inhomogeneous material composition. In general, a binder may be delivered to each layer of a plurality of layers of a powder of inorganic particles. An active component may be introduced, in a spatially controlled distribution, to at least one of the plurality of layers such that the binder, the powder of inorganic particles, and the active component, in combination, form an object. The object may be thermally processed into a three-dimensional part having a gradient of one or more physicochemical properties of a material at least partially formed from thermally processing the inorganic particles and the active component of the object.

A three-dimensional additive manufactured product includes a body portion and a male screw portion integrally disposed on a surface of the body portion so as to protrude therefrom. The male screw portion includes a following side flank forming a first flank angle with respect to a vertical plane to an axis thereof. The first flank angle is not less than 45 degrees.

A component, in particular a stator or a rotor, of an electric motor, in which a layer structure is generated is produced using additive manufacturing, by: forming, via alternate additive production, a layer assembly having first layers and second layers each first layer including a filament containing plastic and metal, and each second layer including a filament containing plastic and ceramic; heating the layer assembly a first temperature, at which the plastic is removed from the layers; further heating the layer assembly (2) to a second temperature, whereby the metal of the layer is sintered and an electrically insulating ceramic layer is obtained from the layer.

A cermet and/or ceramic multi-coloured article, and in particular a bezel (1) of a timepiece, produced by a method for compressing at least two materials (2, 3) of distinct colours, the article including a relief decoration (8) of a different colour from the rest of the article, the decoration (8) being produced by laser ablation on one of the materials (3) after compression of the two materials (2, 3).

A method for realising a ceramic slab, comprising the following steps: arranging on a first deposition plane (50) a decorated layer (L2) provided with a decoration (200), gradually depositing the decorated soft layer (L2) from a head (H) to a tail (T); gradually transferring the soft layer (L2) by deposition from the first deposition plane (50) to a second deposition plane (83), placed at a lower height than the first deposition plane (50), starting from the tail (T) of the second soft layer (L2), gradually realising a second layer (L3) on the second deposition plane (83).
