摘要： A method of calibrating movement of a platform is described, the method comprising: in a calibration run, causing movement of the platform; detecting a plurality of positions of the platform during the movement; deriving a movement pattern from the plurality of positions; and determining an adjustment of the movement of the platform based on the movement pattern.

摘要： There is disclosed a build material supply unit, comprising: a supply chamber body enclosing a supply volume to contain a build material for additive manufacture; an electromagnetic distance sensor to determine a length parameter relating to a length of a beam pathway extending from an emitter of the sensor to a surface level of build material in the supply volume; and a reflector to reflect the beam pathway between the emitter and the surface level of build material; wherein the reflector is spaced apart from the emitter.

摘要： A method of delivering build material from a build material store (404) to a supply module (102). The method comprises moving, using a rotatable vane (116), a portion of build material from the supply module (102) to the top of the supply module (102), and spreading the moved portion of build material across the support platform (104).
