Abstract: This invention concerns an additive manufacturing apparatus for building objects by layerwise consolidation of material. The apparatus comprises a build chamber 101 containing a working area, a plurality of high energy beams 133, 233 for consolidating material deposited in the working area in layers and an optical unit 135 for controlling transmission of the high energy beams onto material in the working area. The optical unit 135 comprises a plurality of independently controllable optical elements 141, 241 each optical element 141, 241 for controlling transmission of at least one of the high energy beams onto the material in the working area, the optical unit 135 movable in the build chamber 101.

Abstract: A non-contact measurement apparatus and method. A probe is provided for mounting on a coordinate positioning apparatus, comprising at least one imaging device for capturing an image of an object to be measured. Also provided is an image analyzer configured to analyze at least one first image of an object obtained by the probe from a first perspective and at least one second image of the object obtained by the probe from a second perspective so as to identify at least one target feature on the object to be measured. The image analyzer is further configured to obtain topographical data regarding a surface of the object via analysis of an image, obtained by the probe, of the object on which an optical pattern is projected.

Abstract: A method of putting a feature of interest on an object and an optical inspection system of a non-contact probe mounted on a positioning apparatus in a desired relationship. The method includes: a) identifying a target point of interest on the object to be inspected by arranging the non-contact probe and object at a first relative configuration at which a marker feature, projected by the non-contact probe along a projector axis that is not coaxial with the optical inspection system's optical axis, identifies the target point of interest; and b) subsequently moving the non-contact probe and/or object so as to put them at a second relative configuration at which the target point of interest and optical inspection system are at the desired relationship, in which the positioning apparatus is configured to guide such motion in accordance with the control path.
