Abstract: There is provided a method of generating print data for use by an additive manufacturing system to generate a plurality of 3D objects within a build chamber having a build surface. First spatial data defining a first 3D object and second spatial data defining a second 3D object is received. First print data is generated to cause the additive manufacturing system to manufacture the first 3D object at least partly from a first build material. Intermediate print data is generated to cause the additive manufacturing system to manufacture a partition comprising a 3D object configured to fill the build chamber in a plane parallel to the build surface. Second print data is generated to cause the additive manufacturing system to manufacture the second 3D object at least partly from a second build material.

Abstract: 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.
