Abstract: A process includes forming a printed article having an external surface and at least one microfeature with an internal surface by additive manufacture, coating the external surface and the internal surface of the printed article with a metallic microlayer to form a coated article, and densifying the coated article to form a component. After formation, the printed article has a porosity such that the printed article is not at full density. A densified component includes a printed article having an external surface and at least one microfeature with an internal surface and a metallic microlayer coating the external surface and the internal surface of the printed article. The printed article is formed by additive manufacture.

Abstract: According to examples, a system may include a first carriage carrying a laying device that may form a build material layer over a build area and a first energy source that may apply energy onto the build material layer as the first carriage is moved over the build material layer. The system may also include a second carriage carrying an agent delivery device and a second energy source, in which the agent delivery device may selectively deliver an agent onto the layer of build material and the second energy source may apply energy onto the agent and the layer of build material as the second carriage is moved across the build material layer. The system may further include a controller to control movement of the first carriage and the second carriage across the build area, in which the first carriage may be independently movable with respect to the second carriage.

Abstract: Methods of preparing a particulate build material for three-dimensional printing can include loading fresh particulate build material including from about 80 wt % to 100 wt % fresh metal particles into a mechanical mixer, and mechanically conditioning the fresh particulate build material to generate conditioned particulate build material including conditioned metal particles. The fresh metal particles can have a surface oxide layer, and the fresh particulate build material can have a particle size distribution with a D10 particle size from about 2 μm to about 10 μm, a D50 particle size from about 5 μm to about 20 μm, and a D90 particle size from about 20 μm to about 40 μm. The conditioned particulate build material can include a modified cohesive index (compared to the fresh conditioned particulate build material) ranging from about 25 cohesive index units to about 35 cohesive index units.

Abstract: An additive manufacturing machine includes a plurality of subsystems, such as a condensate evacuation subsystem for removing byproducts of the additive manufacturing products near a powder bed, a closed loop subsystem for cleaning contaminants from sensitive machine components, and/or an electronics cooling subsystem for cooling an electronics compartment. Each subsystem may include a dedicated gas circulation loop that is operably coupled to a gas circulation device for urging a clean flow of gas to each of the subsystems to perform a particular function.

Abstract: A method for producing a counter-form (20) for manufacturing a part having a complex shape (24) by pressure sintering densification. The counter-form (20) is formed from successive layers produced by numerically-controlled three-dimensional (3D) additive printing according to the following steps: numerically recording a three-dimensional negative of the part to be produced (24) in a control unit of a three-dimensional additive printing system in order to constitute the positive form of the counter-form to be produced; producing the counter-form (20) using a 3D additive printing technique. The part having a complex shape (24d) is then manufactured by pressure sintering, then separated from the counter-form which is also sintered (20).

Abstract: In an embodiment, a method of manufacturing customized ceramic labial/lingual orthodontic brackets by additive manufacturing may comprise measuring dentition data of a profile of teeth of a patient, based on the dentition data, creating a three dimensional computer-assisted design (3D CAD) model of the patient's teeth, and saving the 3D CAD model, designing a virtual 3D CAD bracket structure model for a single labial or lingual bracket structure based upon said 3D CAD model, importing data related to the 3D CAD bracket structure model into an additive manufacturing machine, and directly producing the bracket with the additive manufacturing machine by layer manufacturing from an inorganic material including at least one of a ceramic, a polymer-derived ceramic, and a polymer-derived metal.
