Abstract: A computer-implemented method is disclosed. The computer-implemented method comprises receiving data indicative of a post-manufacture treatment to be applied to a three-dimensional object following completion of a manufacturing process to generate the three-dimensional object; and determining, based on the received data indicative of the post-manufacture treatment, build parameters to be applied in respect of the manufacturing process. A manufacturing apparatus and a machine-readable medium are also disclosed.

Abstract: A system includes a controller to receive data corresponding to an object or slices of the object to be generated by a 3D printer, wherein the 3D printer includes an array of printhead nozzles to selectively eject a print agent on a layer of build material in a build chamber having a build chamber wall, the array of printhead nozzles spanning substantially the full width of the build chamber and moveable along a length of the build chamber. The controller to generate first print data used to generate layers of the object based on the received object data, and to generate second print data used to generate layers of a sacrificial barrier located between the object and the build chamber wall, the second print data is generated such that different parts of the sacrificial barrier are generated using a different plurality of nozzles of the array of printhead nozzles.

Abstract: In certain examples, a method comprises determining a fusing area density distribution of a build layer from build data relating to a build layer of a three-dimensional model to be printed by an additive manufacturing system. The method comprises, in response to a determination that a region of the build layer has a fusing area density outside of a fusing area density tolerance window, modifying the build layer to define a build layer in which the region has a fusing area density that is within the fusing area density tolerance window.

Abstract: In an example, a method includes receiving, at least one processor, object model data representing at least a portion of a first object that is to be generated by an additive manufacturing apparatus by fusing build material within a fabrication chamber. An indication of an amount of fused build material in a region of the fabrication chamber which is to be below the region in which the first object is to be generated may be determined and a dimensional compensation value to apply to the object model data representing the first object may be determined based on the determined indication. The determined dimensional compensation value may be applied to the object model data to derive modified object model 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: An example method of generating three-dimensional objects is disclosed. Object generation instructions to generate the object may be determined by defining a shell region of a layer of build material corresponding to the first portion of the object having a first color, and defining a fusing agent region on a layer of build material adjacent to the shell region on which fusing agent of a second color is to be applied and specifying an amount of colorant to be applied to the shell region wherein the object generation instructions specify application of fusing agent and colorant such that, when the layer of build material is heated using a heat source, the fusing agent region of the build material melts due to energy absorbed from the heat source and the build material of the shell region melts due, at least in part, to energy transfer from the fusing agent region.

Abstract: An example of an apparatus is disclosed. The example disclosed herein comprises a sensor and a controller. The sensor, coupled to the controller, is to measure a temperature from a three-dimensional printing build material layer. The controller is to control an energy source to apply energy to the build material layer. The controller is further to measure a temperature from the build material layer using the sensor. The controller is also to determine a build material quality level comprising at least one of a first quality level, a second quality level, and a third quality level based on the measured temperature.

Abstract: Object model data defining a plurality of objects to be built by a three-dimensional printing apparatus is obtained. The plurality of objects to be built are arranged in a configuration to be printed with objects having a first property arranged in a first separable region of a build volume and objects having a second property arranged in a second separable region of the build volume. Print data defining the configuration of the plurality of objects to be built is generated.
