摘要： In an example, a method includes forming a first layer of build material to be processed in object generation and selectively applying at least one print agent on to the first layer based on a print instruction for the first layer. Energy may be applied to the first layer to cause fusion in at least a region thereof, and at least one temperature associated with a thermal contribution of the first layer to a subsequent layer of build material to be processed in object generation may be measured. It may be determined if a temperature condition indicative of a departure from an anticipated thermal contribution of the first layer to a region of subsequent layer exists. If such a temperature condition does exist, a print instruction for applying print agent to the region of the subsequent layer based on the temperature condition may be determined.

摘要： Examples of additive manufacturing are described. In one example, a method comprises generating print data to cause application of fusing agent to a first region of a layer of build material of an object undergoing additive manufacturing, the first region corresponding to an inner region of an object undergoing additive manufacturing. The print data causes application of fusing agent and detailing agent to a second region of the layer, the second layer corresponding to a middle region of the object. The print data causes application of detailing agent to a third region of the layer, the third region corresponding to an outer layer of the object. Fusing energy is applied to the layer.

摘要： Temperatures of a layer of build material on a support member may be detected. Each of the temperatures corresponding to a respective area of the layer. Based on data representing the three-dimensional object, a subset of the temperatures may be filtered from spatial temperature distribution data comprising the temperatures. A degree of heat or energy applied to the layer may be controlled based on the filtered spatial temperature distribution data.

摘要： 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).

摘要： Apparatus (100) for generating a three-dimensional object comprising a support (101) to receive build material, and a calibration platform (103) to receive a print media for use with a calibration operation performed by the apparatus. The calibration platform (103) may be moveable between a non-calibration position when the apparatus is operating in a building mode of operation, and a calibration position when the apparatus is operating in a calibration mode of operation.

摘要： Methods of generating a three-dimensional object with an additive manufacturing system are described. The method includes depositing a build material within a working area, thereby providing a build material layer, selectively depositing a fusing agent onto a portion of the build material layer, applying energy from a bulk-fusion energy source to the working area, thereby fusing at least a portion of the build material where the fusing agent is deposited, and applying energy from a focused energy source to one or more localized areas of the working area.

摘要： A method for determining a parameter of a process associated with a 3D printing process provided. A first amount corresponding to an object of fused powder surrounded by non-fused powder is used. The first amount is separated into a second amount of non-fused powder and a third amount corresponding to the object including residual powder material attached. The residual powder material is removed from the object using a fourth amount of a cleaning agent. A fifth amount corresponding to the fused powder of the cleaned object and a sixth amount of material corresponding to a mixture of the removed residual powder material and the cleaning agent is obtained. The mixture includes a seventh amount of material being recovered, an eighth amount of material corresponding to powder material wastage, and the fourth amount. The parameter is derived from at least two of first to eighth amounts of material.
