1. A powder bed fusion apparatus for building an object in a layer-by-layer manner, the powder bed fusion apparatus comprising a build platform movable within a build sleeve to define a build volume, the build platform for supporting a powder bed within the build volume, an irradiation device arranged to generate an energy beam and a scanner arranged to steer the energy beam to irradiate powder of the powder bed to selectively fuse the powder bed and a mechanical manipulator arranged to engage with the object and/or a build substrate, to which the object is attached, to tilt the object such that powder is freed from the object, wherein the mechanical manipulator comprises an end effector positionable to receive the object and/or the build substrate when conveyed from the build sleeve such that the object and/or the build substrate attach to the end effector, wherein subsequent movement of the end effector tilts the object.
