Abstract: A powder bed fusion apparatus for building an object in a layer-by-layer manner includes a build platform movable within a build sleeve to define a build volume, a layer formation device for forming layers of powder across the build volume in a working plane and an irradiation device for irradiating powder in the working plane to selectively fuse the powder. The powder bed fusion apparatus further includes a mechanical manipulator arranged to engage with the object and/or a build substrate, to which the object is attached, to tilt the object in a raised position above the working plane such that powder is freed from the object and deposited at a location above the working plane and/or into the build volume.

Abstract: A method of manufacturing an article comprising: (a) performing an additive manufacturing process to firm an article in an initial state, the article comprising mounting features and being supported during the additive manufacturing process by support structures; and (h) performing a second manufacturing process to transform the article into a second state, which second manufacturing process is a subtractive process comprising: (i) mounting, via the mounting features formed during the additive manufacturing process, the article in a holding device of a machine for operating on the article, with the support structures or at least remnants thereof remaining on the article, and (ii) with the article so mounted in the holding device, processing at least one feature on a surface of the article on which the support structures were provided to remove material on the at least one feature provided by the support structures.

Abstract: A method of manufacturing an article, comprising taking an article formed in an initial state via an additive manufacturing process and performing a second manufacturing process to transform the article into a second state, which comprises mounting the article in a holding device, processing at least one first feature on the article, which comprises processing at least one set of mounting features on the article, re-mounting the article via the at least one set of mounting features, and then processing at least one second feature on the article.
