Abstract: A printer is disclosed. The printer has a print engine that mounts a first printhead and a second printhead adjacent to the first printhead in a staggered line of overlapping printheads. Each printhead has at least one row of nozzles. The blending nozzles in the first printhead overlap with blending nozzles in the second printhead. When printing, the non-overlapping nozzles in the first printhead use a default ink modulation amount and the blending nozzles in both printheads use a scaled ink modulation amount.

Abstract: In an example a method includes identifying, by a processor, in a data model of at least a portion of a three-dimensional object, an object property associated with a location in the three-dimensional object. A data model of a virtual build volume comprising at least a portion of the three-dimensional object may be generated in which an association with an object property is dispersed beyond the location.

Abstract: In an example, a method includes acquiring, at a processor, a data model of an object to be generated in additive manufacturing, the data model comprising object model data representing a slice of the object model as a plurality of polygons and object property data comprising property data associated with the plurality of polygons. The slice may be inspected from a predetermined perspective at a plurality of discrete locations. It may be determined if each location is within a face of a polygon, and if so, the object property data associated with that polygon may be identified and associated with that location. The slice may further be inspected at a plurality of discrete locations along an edge of a polygon, the object property data associated with each location may be identified and associated with that location.

Abstract: In an example, a method includes receiving object model data describing at least a portion of an object to be generated by additive manufacturing. Object generation instructions for generating the object in its entirety may be derived based on the object model data. Where it is determined that the object model data comprises a data deficiency for deriving the object generation instructions, at least one attribute for the object may be inferred and object generation instructions may be derived based on the object model data and the inferred attribute.

Abstract: In an example, a method includes receiving, at a processor, a data model of an object to be generated in additive manufacturing. A virtual build volume comprising a representation of at least a portion of the object may be segmented into a plurality of nested segments comprising a core segment and a peripheral segment. Segmenting the virtual build volume may comprise determining a dimension of the peripheral segment based on at least one of a geometry of the object and an intended object property.

Abstract: In an example, a method includes receiving, at a processor, a data comprising a model of an object to be generated in additive manufacturing. The data comprises object model data representing an object model as a plurality of initial polygons and object property data associated with the initial polygons. The method may comprise generating a representation of a slice of the object model defined between two planes and generating a plurality of polygons to represent the slice of the object model. A mapping between the object property data and the generated plurality of polygons may also be generated.

Abstract: According to one example, there is provided a method of generating three-dimensional objects in a three-dimensional printing system comprising a pair of movable build modules. The method comprises moving a first build module into a build position, executing a 3D print job in the first build module, moving the first build module into a post-build position, performing post-processing operations on the first build module, moving a second build module into the build position, and executing a 3D print job in the second build module.
