摘要： 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.

摘要： 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.

摘要： 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.

摘要： A method includes receiving an object model describing a geometry of a three-dimensional, 3D, object for printing by a 3D printer, and build material data indicating a selected build material to be used in printing the 3D object by the 3D printer. A volume to surface area ratio of the object model is calculated. In response to the volume to surface area ratio being greater than a first predetermined threshold value for the selected build material, it is determined that printing the 3D object by the 3D printer from the selected build material is expected to result in a defect in the 3D object.

摘要： 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.

摘要： In an example, a method includes receiving, by at least one processor, object model data, the object model data describing at least part of an object to be generated in additive manufacturing. Pattern data is also received, wherein the pattern data describes a pattern of variable opacity intended to be formed internally to the object. Object generation instructions for generating an intermediate layer of the object comprising the pattern of variable opacity may be determined by at least one processor.
