Abstract: In an example, a method includes forming, at an additive manufacturing apparatus, a first layer of build material to be processed in the generation of an object. A print agent is selectively applied onto the first layer based on a first print instruction associated with the first layer. Energy is applied to the first layer to cause fusion in a region of the first layer. The method further comprises: measuring the temperature of the first layer at a plurality of locations to form a measured temperature distribution profile; comparing the measured temperature distribution profile against a predicted temperature distribution profile to generate a difference; and correcting a temperature distribution profile of a subsequent layer of the build material following fusion of the subsequent layer based on the difference by modifying a second print instruction associated with the subsequent layer.

Abstract: A method includes printing an image on substrate by a printhead using ultraviolet (UV) curable ink. The method includes selectively applying a first amount of UV radiation by a first region of a light source to a first area of the image after a first amount of time passes from printing the first area to form a first gloss level area having a glossy finish. The method also includes selectively applying a second amount of UV radiation by a second region of the light source to a second area of the image after a second amount of time passes from printing the second area to form a second gloss level area having a matte finish. At least one of the second amount of UV radiation is greater than the first amount of UV radiation and the first amount of time is greater than the second amount of time.

Abstract: There is provided a method of generating print data for use by an additive manufacturing system to generate a plurality of 3D objects within a build chamber having a build surface. First spatial data defining a first 3D object and second spatial data defining a second 3D object is received. First print data is generated to cause the additive manufacturing system to manufacture the first 3D object at least partly from a first build material. Intermediate print data is generated to cause the additive manufacturing system to manufacture a partition comprising a 3D object configured to fill the build chamber in a plane parallel to the build surface. Second print data is generated to cause the additive manufacturing system to manufacture the second 3D object at least partly from a second build material.

Abstract: Examples are described that generate control data (280) for production of a three-dimensional object. Build material profile data (260) is accessed for an indicated build material. The build material profile data for a given build material defines one or more parameter values that are dependent on the properties of the given build material and that are configured to generate a three-dimensional object with predefined build properties. Certain examples are arranged to generate control data for the production of a three-dimensional object by applying build material profile data to received object data (230).

Abstract: Certain examples described herein relate to preparing a base of build material for additive manufacturing. The base is formed from layers of build material that do not form part of an object undergoing additive manufacture. The base is heated by the application of energy, for example using a radiation source. A thermal profile of the base is measured after heating and is used to determine a pattern of application of at least one printing agent to the base. The pattern of application is used to deposit the at least one printing agent upon the base, wherein the presence of the printing agent affects the heating of the base. In this way the pattern of application of printing agent may be used to effect a thermal homogeneity of the base.

Abstract: A detector or sensor including a transistor having a sensor element that generates a current when exposed to a stimulus such as light or a chemical, in one implementation, the sensor element is positioned between a transistor gate and a transistor channel. When the sensor element is not being exposed to the stimulus, the transistor outputs a first voltage on a transistor drain contact when the transistor inverts. When the sensor element is being exposed to the stimulus, the transistor outputs a second voltage on the transistor drain contact when the transistor inverts, where the second voltage is higher than the first voltage.
