Abstract: In an example, a method includes receiving, at a processor, data representing at least part of an object to be manufactured in a layer-by-layer manufacturing process. A serialised octree representation of at least part of the object may be generated from the data. In the serialised octree representation, nodes are ordered such that (i) a node representing a volume which includes a layer of the object to be generated earlier in an intended order of object generation precedes a node representing a volume which consists of layer(s) of the object to be generated subsequently; (ii) nodes representing a volume which includes a given layer of the object are ordered based on a level of the nodes within the octree representation, wherein parent nodes appear before descendent nodes; and (iii) nodes representing a volume which includes a given layer of the object and being of the same level within the octree representation are ordered according to a location encoding pattern.

Abstract: A method comprises receiving object model data in an original coordinate system to print within a predefined usable build volume of a three dimensional printer. The method comprises receiving at least one compensation factor for the object model data to compensate for any shrinking of an object. The method comprises scaling the object model data by the at least one compensation factor to provide printable object model data. The scaling is performed with reference to an origin at a centre of the usable build volume.

Abstract: An image may be printed at variable speed. An image density profile provides an estimation of power to be consumed while printing the image. A power consumption profile is generated based on the image density profile and by taking into account distance offsets between nozzles that are used to print the image. The image may be printed at different speeds based on the power consumption profile.

Abstract: An example apparatus is for printing to a substrate. The example apparatus comprises a printing fluid device and an air flow device. The printing fluid device is for transferring printing fluid to a substrate. The air flow device is to create an air curtain so that any printing fluid residue from the transfer of the printing fluid to the substrate is at least partially prevented from migrating toward a user of the apparatus.

Abstract: In some examples, an imaging device may include a controller including processing circuitry to detect, a first quantity of rows of pixels to be included as a first band of a contone image, process the pixels of each row of the first band in parallel raster order, detect a second quantity of rows of pixels to be included as a second band of the contone image; and process the pixels of each row of the second band in response to the completion of the pixels of the first band, where the rows of the second band are processed in parallel in serpentine order with respect to the first band.

Abstract: In an example, a method includes receiving, at a processor, data representing a three dimensional object. Using the processor, a modified data representation of the three dimensional object may be determined wherein, in the modified data representation, the three dimensional object is represented in terms of homogenous sub-volumes. Each homogenous sub-volume is homogenous with respect to a predetermined attribute and contains locations which are within a common object boundary distance band of plurality of object boundary distance bands, wherein at least two object boundary distance bands partially overlap.

Abstract: According to an example, an apparatus may include a processor and a memory. The memory may have stored thereon machine readable instructions that may cause the processor to access an initial halftone image of a three-dimensional (3D) object, the initial halftone image being generated from a continuous tone image of the 3D object. The instructions may also cause the processor to iteratively modify voxel data for the initial halftone image to identify updated voxel data that more accurately corresponds to the continuous tone image than the initial halftone image and to generate halftone image printing data for the 3D object containing the updated voxel data.

Abstract: In an example, a method includes measuring a temperature of a plurality of regions of a layer of build material in an additive manufacturing apparatus to provide initial temperature values. For each of a plurality of regions which comprise build material which is intended to fuse, an average temperature value of a plurality of neighbouring regions may be determined and the initial temperature values may be replaced with the average temperature value. Based on the replacement temperature values, a representative temperature of an area of the layer of build material may be determined and a heat source may be controlled based on the representative temperature.

Abstract: In an example, a method includes acquiring, at a processor, a first data model and a second data model. The first data model comprises a representation of at least one property of at least part of a first object and the second data model comprises a representation of at least one property of at least part of a second object. The first and second objects are to be generated in a common additive manufacturing operation. The method may include generating a first print layer model and a second, different, print layer model using the processor by combining at least parts of the first data model and the second data model and generating additive manufacturing instructions based on the first print layer model and the second print layer model.
