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 coordinate positioning machine includes a plurality of drive axes, each being a rotary or linear drive axis, for positioning a platform within a working volume of the machine, and a separate linear counterbalance axis for counterbalancing the platform. With this arrangement the counterbalance axis can be substantially invariant to changes in orientation of the drive axes and can be counterbalanced by a simple counterweight. Also, an arrangement wherein the counterbalance axes and force generator are arranged so horizontal movement of the platform causes substantially no net movement of and/or no work to be done on the generator. Also, an arrangement wherein a series of counterbalance axes has at least one rotary counterbalance axis, and the generator is arranged behind or at a predetermined distance from the counterbalance axis. Also, an arrangement having a series of counterbalance axes with at most one rotary counterbalance axis between the generator and ground.

Abstract: A method and apparatus for determining an alignment of an optical scanner for directing an electromagnetic beam to locations within a scan field. The method may include locating a reference element within the scan field of the optical scanner and controlling the optical scanner to cause the electromagnetic beam to be directed to a plurality of different points in the scan field, including at least one point on the reference element. Reflected electromagnetic radiation is detected. The method may include determining when the electromagnetic beam is directed to a reference position in the scan field given by the reference element from a comparison of an intensity of the detected electromagnetic radiation for the different points and determining a corresponding demand signal that causes the optical scanner to direct the electromagnetic beam to the reference position.

Abstract: A non-Cartesian coordinate positioning machine is provided that comprises an extendable leg assembly for positioning a component such as a measurement probe within a working volume of the machine, and a constraint member associated with the extendable leg assembly for providing a predetermined part of the extendable leg assembly with substantially a same orientation relative to gravity for a same position of the component within the working volume. In a preferred embodiment, the orientation relative to gravity is maintained substantially constant, so that a plane defined by the predetermined part is substantially aligned with gravity, as the component is moved around the working volume.

Abstract: A method of forming an encoder scale for a measurement device is disclosed. The method comprises taking a laser and a substrate carrying an etch-resistant film. Parts of the etch-resistant film are removed by use of the laser, thereby forming a pattern on the substrate that defines an encoder scale, and the substrate is etched through the parts of the etch-resistant film that have been removed by the laser.
