The communications interface is to transmit data from the data source to the additive manufacturing build material processing apparatus.

Abstract: In an example, a data unit includes a data unit mounting having a circuitry region, a registration portion, and a retaining feature. Circuitry comprising a data source to provide at least one additive manufacturing parameter is arranged on the circuitry region of the mounting. The data unit mounting is to be removably mounted on a receiving portion of an additive manufacturing build material component, such that the registration portion is to be received in a corresponding guide portion of the receiving portion of the additive manufacturing build material component, and the retaining feature is prevent removal of the data unit from the receiving portion unless deformed. Deformation of the retaining feature to effect removal of the data unit from the receiving portion may be a permanent deformation.

Abstract: Methods of generating a three-dimensional object with an additive manufacturing system are described. The method includes depositing a build material within a working area, thereby providing a build material layer, selectively depositing a fusing agent onto a portion of the build material layer, applying energy from a bulk-fusion energy source to the working area, thereby fusing at least a portion of the build material where the fusing agent is deposited, and applying energy from a focused energy source to one or more localized areas of the working area.
