    Abstract: There is disclosed additive manufacturing apparatus comprising: a controller to: receive object data relating to an object to be generated; and define print data for additive manufacture of the object by ejection of a print agent on build material in a pattern corresponding to selective fusing of the build material, wherein the print data is defined based on the object data so that the pattern defines a shield feature embedded within the object to inhibit fusing of build material corresponding to the shield feature relative build material corresponding to an adjacent portion of the object; and a print agent distributor to eject a print agent on build material based on the print data.

    Abstract: Certain examples described herein relate to preparing a base of build material for additive manufacturing. The base is formed from layers of build material that do not form part of an object undergoing additive manufacture. The base is heated by the application of energy, for example using a radiation source. A thermal profile of the base is measured after heating and is used to determine a pattern of application of at least one printing agent to the base. The pattern of application is used to deposit the at least one printing agent upon the base, wherein the presence of the printing agent affects the heating of the base. In this way the pattern of application of printing agent may be used to effect a thermal homogeneity of the base.

    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.
