摘要： An additive manufacturing apparatus for building objects by layerwise consolidation of material. The apparatus includes a build chamber containing a working area, a plurality of high energy beams for consolidating material deposited in the working area in layers and an optical unit for controlling transmission of the high energy beams onto material in the working area. The optical unit includes a plurality of independently controllable optical elements each optical element for controlling transmission of at least one of the high energy beams onto the material in the working area, the optical unit movable in the build chamber.

摘要： A method of building up a measurement data set for a surface of an object using an analog measurement probe mounted on a machine tool apparatus which obtains scanned measurement data of the surface over a plurality of offset traverses. Subsequent traverses are offset from previous traverses such that over a series of traverses the analog probe's surface detecting region progresses i) laterally across the object, and/or ii) away from or towards the object. The course of relative motion for at least one subsequent traverse is generated and/or updated based on data obtained during at least one previous traverse.
