Abstract: A three-dimensional additive manufacturing device, which performs additive manufacturing by irradiating, with a beam, a powder bed laid on a build surface area, includes a projection unit that is configured to project a pattern in which there is a luminance distribution in the build surface area and the luminance distribution changes over time, an imaging unit configured to image the pattern projected onto the build surface area, and a reflective part configured to reflect at least one among a first light beam projected by the projection unit and a second light beam captured by the imaging unit. The projection and imaging units are disposed outside the chamber where the additive manufacturing is performed on the build surface area. The reflective part is accommodated inside the chamber. The first and second light beams pass through one first window portion installed on the chamber.

Abstract: Methods of manufacturing a plurality of components during an additive manufacturing process by means of a powder including particles, which is at least locally melted in order to form the plurality of components. The plurality of components can be formed in a component layer extending along a manufacturing plane, in which a first component lies adjacent to a second component of the component layer at least in a spatial direction along the manufacturing plane. In this connection it is proposed to provide a gap having a gap width between the first component and the second component of the component layer, which is predefined using a particle size distribution of the particles in the powder.

Abstract: A method of making a gold-titanium alloy can include preparing a powder mixture of gold source powder and titanium source powder. The method can also include consolidating the powder mixture to form a consolidated body. The consolidated body can be at least partially sintered in vacuum or a reducing atmosphere to for a gold-titanium alloy sintered article.
Another example method of producing a gold-titanium alloy can include preparing a composite metal powder having composite granules including a gold source powder and a titanium source powder within the composite granules. The composite metal powder can be consolidated to form a consolidated body. The consolidated body can be at least partially sintered to form a sintered article. The method can also include deoxygenating at least one of the composite metal powder, the consolidated body, or the sintered article at a deoxygenation temperature under a hydrogen-containing atmosphere to reduce an oxygen content.

Abstract: The disclosed embodiments relate to the monitoring and control of additive manufacturing. In particular, a method is shown for removing errors inherent in thermal measurement equipment so that the presence of errors in a product build operation can be identified and acted upon with greater precision. Instead of monitoring a grid of discrete locations on the build plane with a temperature sensor, the intensity, duration and in some cases position of each scan is recorded in order to characterize one or more build operations.
