    Abstract: In an example, a method includes acquiring, at a processor, object generation source data representing a three-dimensional object to be generated in additive manufacturing. A dataset which is representative of an aspect of the three-dimensional object may be determined from the object generation source data. Digital security may be applied to the object generation source data and the dataset. The digital security applied to the object generation source data may be different from that which is applied to the dataset.

    Abstract: Certain examples described herein relate to a removable unit for a three dimensional printing system. The removable unit comprises at least one compartment to store build material for a three-dimensional print job, a coupling to engage with a printer device of the three-dimensional printing system, and a memory. The memory is configured to store instructions for the three-dimensional print job for the printer device, and the instructions are readable from the memory by the printer device when the removable unit is engaged with the printer device.

    Abstract: One example of a method includes receiving a three-dimensional (3D) model of an object to be 3D printed and voxelizing the 3D model to define a plurality of voxel layers. Each voxel layer defines a plurality of voxel rows including an initial voxel row. The method includes for each voxel layer: exclusively oring (XORing) a key voxel row with the Initial voxel row to provide an initial delta row; and for each voxel row from the voxel row following the initial voxel row to a further voxel row of the plurality of voxel rows, XORing each voxel row with the previous voxel row to provide a delta row for each voxel row.

    Abstract: A method is described in which data representing a three-dimensional object to be printed is obtained. The data comprises object property data indicative of properties of the three-dimensional object. Layers within the three-dimensional object to be printed are identified. The obtained data is processed by comparing object property data associated with an identified layer to object property data associated with a reference layer selected from the identified layers. Where a difference in object property data associated with an identified layer and object property data associated with a reference layer is determined, the determined difference is stored.
