A method of additively manufacturing an object includes steps of: (1) selectively depositing build powder inside of a build contour of the object to form a build-powder section of a powder layer; and (2) selectively depositing support powder outside of the build contour to form a support-powder section of the powder layer. According to the method, the build powder includes a build-powder composition, the support powder includes a support-powder composition, and the build-powder composition and the support-powder composition are different.

A method of additively manufacturing an object includes steps of: (1) successively forming a plurality of powder layers by depositing powder; (2) selectively controlling a composition of the powder that forms each one of the plurality of powder layers; and (3) successively forming a plurality of object layers of the object by joining the powder of a portion of each one of the plurality of powder layers before forming each successive one of the plurality of powder layers.

A recoating unit for equipping and/or retrofitting a device for producing a three-dimensional object by means of selectively solidifying, layer by layer, of a building material in powder form. The recoating unit is configured, depending on its movement in the first direction or in its opposite direction, to receive building material in that chamber that is the trailing chamber in the respective direction of movement and to spread the building material received in the respective trailing chamber to a uniform layer by means of the respective trailing recoating element.

The invention relates to a forming method of an alloy comprising predominantly Ti β or nearby β stage, comprising the steps of: Preparation of a homogeneous mixture of particle powder comprising micrometric particles of pure Ti and nanoscale particles of at least one additional element or compound promoting the beta phase of the Ti during its cooling from its phase transition temperature. exposing said particle powder mixture to a focused energy source that is selectively heat at least a portion of a bed of said homogeneous powder mixture at a temperature between 850 and 1850° C. cooling of the part having undergone this exposure with conservation of the phase b of the Ti.

A method and system for providing cooling to a part formed using high-temperature additive manufacturing process. Infrared sensors or cameras are used to measure sidewall temperatures and, optionally, top layer temperature. Coolant nozzles provide cooling to the sidewalls of the finished layers and, optionally, to the top layer. The coolant intensity of the coolant nozzles is controlled in order to reduce temperature gradients between layers and/or to maintain temperatures in each layer below preferred maximum temperature.

Examples of a cosmetic agent are for three-dimensional (3D) printing. In an example, the cosmetic agent includes a dye, an oxidizing agent, and a solvent. The oxidizing agent is to react with an antioxidant in a build material to reduce reduction of the dye in the presence of the antioxidant.

A method and a device are provided for removing surface oxides on nodules of a metal powder, before the nodules of the metal powder are used in an industrial process in which the nodules of the metal powder are assembled via a solid route or via a liquid route. In the method and the device, the surface oxides are stripped from the nodules of the metal powder by bringing the nodules of the metal powder into contact with vapour from at least one of: sublimation of a stripping solid material, and sublimation of the stripping solid material followed by a chemical transformation of a product of the sublimation.
