An apparatus and method for removing support material from and/or smoothing surfaces of an additively manufactured part is disclosed. The apparatus may include a chamber, a support surface within the chamber, one or more nozzles within the chamber, a tank positioned below the nozzles, and a vision system. The vision system includes one or more cameras and other imagery obtaining sensors located in the chamber. The cameras and sensors obtain imagery of the additively manufactured part as it is being sprayed to finish the part. The imagery is displayed on a display panel located outside the apparatus or stored for later playback.

A method of manufacturing a cold plate includes forming a fluid circuit on a build surface in a layer-by-layer fashion from a build material. The fluid circuit includes a plurality of peripheral walls, each of the plurality of peripheral walls at least partially defining a primary channel, a longitudinally one of the peripheral walls being formed to include apertures configured to permit excess build material to pass therethrough. A central wall of the fluid circuit at least partially defines the primary channel and a plurality of secondary channels fluidly connected to the primary channel. The method further includes removing excess build material through the apertures.

A method of fabricating a near net shape component includes forming a sacrificial shell from a pulverant material using an additive manufacturing process, the shell having an aperture. The method further includes filling the shell with a second pulverant material, subjecting the filled shell to a consolidation process, and removing the shell from the consolidated second pulverant material.

A heat exchanger includes a base and a plurality of substantially parallel and substantially vertical walls spaced apart and integrally formed with the base via additive manufacturing. The heat exchanger also includes at least one parting sheet not integrally formed with the plurality of walls, but being attached to the plurality of walls, defining flow channels between the walls, the base, and the at least one parting sheet.

A de-powdering basket comprises an enclosure of at least one side wall and a bottom wall. The enclosure is configured such that, when the enclosure is disposed within a build box, the outer surfaces of the at least one side wall are substantially adjacent to the interior walls of the build box. The enclosure further comprises one or more apertures disposed within the at least one side wall, each of the apertures comprising a void that extends through the at least one side wall from an interior surface of the side wall to an exterior surface of the side wall. The enclosure may be configured to accommodate a build plate situated within the enclosure. Outer edges of the build plate may cooperate with inner surfaces of the side walls of the enclosure to prevent loose powder from passing between the outer edges of the build plate and the side walls.

Apparatus (1) for additively manufacturing of three-dimensional objects (2) by means of successive layerwise selective consolidation of layers of a build material, comprising a build material removal device (3) with at least one build material removal unit (4) adapted to remove non-consolidated build material (5) surrounding an additively built object (2), wherein the build material removal device (3) comprises a build material removal chamber (6) delimiting a build material removal volume (7), wherein the build material removal chamber (6) is arranged or arrangeable above the object (2), wherein the object (2) is successively moveable into the build material removal chamber (6), wherein the at least one build material removal unit (4) is adapted to remove non-consolidated build material (5).

An apparatus is disclosed to create a breakaway junction for 3D printed parts. Powder is spread along a target zone, such as a build bed. A liquid functional agent is selectively dispensed upon the powder to form a 3D object, a supporting part, and the breakaway junction between them.
