    Abstract: A selective solidification apparatus includes a build chamber, a build platform lowerable in the build chamber, a wiper for spreading powder material across the build platform to form successive powder layers of a powder bed, an energy beam unit for generating an energy beam for consolidating the powder material, a scanner for directing and focussing the energy beam onto each powder layer and a processor for controlling the scanner. The processor is arranged to control the scanner to scan the energy beam across the powder bed to consolidate powder material either side of the wiper when the wiper is moving across the powder bed and to scan the energy beam across at least one of the powder layers during two or more strokes of the wiper across the powder bed.

    Abstract: A method of monitoring an additive manufacturing apparatus. The method includes receiving one or more sensor signals from the additive manufacturing apparatus during a build of a workpiece, comparing the one or more sensor signals to a corresponding acceptable process variation of a plurality of acceptable process variations and generating a log based upon the comparisons. Each acceptable process variation of the plurality of acceptable process variations is associated with at least one state of progression of the build of the workpiece and the corresponding acceptable process variation is the acceptable process variation associated with the state of progression of the build when the one or more sensor signals are generated.

    Abstract: A method builds a workpiece using an additive manufacturing process, wherein the workpiece is built up by consolidating material in a layer-by-layer manner. The method includes receiving an initial geometric model defining surface geometry of the workpiece, determining workpiece slices to be consolidated as layers of the workpiece during the additive manufacturing process from the initial geometric model, determining adjusted positions of the workpiece slices adjusted from initial positions of the workpiece slices as determined from the initial geometric model, the determination of the adjusted positions based upon warping of the workpiece expected to occur during or after the additive manufacturing process, and building the workpiece using the additive manufacturing process, wherein the workpiece slices are formed in the adjusted positions.
