Abstract: A three-dimensional object is generated using a build material and a printing agent. A visible property of one of the build material and the printing agent is identified. The other of the build material and the printing agent is selected based at least on the other of the build material and the printing agent having a given visible property. A three-dimensional object is generated using the one of build material and the printing agent having the identified visible property and the other of the build material and the printing agent having the given visible property. The selecting is based at least on the identified visible property and the given visible property having a desired visible property relationship. An apparatus for building a three-dimensional object is also disclosed.

Abstract: According to one example, there is provided a method of determining characteristics of a build material. The method comprises obtaining a first quantity of a first build material, determining, for the first build material, the proportion of non-marked build material and marked build material, determining, based on the determined proportion, a first quantity of the first build material to be combined with a second quantity of a second build material to produce a third quantity of mixed build material having a predetermined proportion of marked build material.

Abstract: Examples are described that generate control data for production of a three-dimensional object. Build material profile data 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.

Abstract: In an example, a method of anticipating maintenance in a printing device includes determining an inertial reference signal of a printer carriage and measuring a current inertial signal of the printer carriage. The method includes cross-correlating the inertial reference signal with the current inertial signal and determining from the cross-correlating when the current inertial signal is not within a preset confidence interval of the inertial reference signal.

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.
