  • Patent number: 11225014
    Abstract: According to an example, a 3D printer may include a delivery device and a controller. The controller may access a morphology of a part to be formed from a plurality of build materials in a layer, determine, based upon the accessed morphology, a first delivery pattern for the delivery device to selectively deliver liquid droplets onto build materials in the layer during a first pass over the layer and a second delivery pattern for the delivery device to selectively deliver liquid droplets onto build materials in the layer during a second pass over the layer to control a property of the part formed of some of the build materials in the layer. The controller may also control the delivery device to selectively deliver liquid droplets onto build materials in the layer according to the determined first and second delivery patterns respectively during the first pass and the second pass.

  • Publication number: 20210331403
    Abstract: An example method includes acquiring a model of an object to be generated in three-dimensional object generation which is segmented into a plurality of object model sub-volumes, each sub-volume representing a region of the object which is individually addressable in object generation. Object model sub-volumes within a first depth of an object model surface are defined at a first resolution and object model sub-volumes beyond the first depth are defined at a second resolution, and the first resolution is a higher resolution than the second resolution. An object generation model is applied to the object model to determine at least one predicted dimensional deviation of the object in object generation. A geometric adjustment to the segmented object model may be determined to compensate for the predicted dimensional deviation by adding and/or removing at least one object model sub-volume defined at the first resolution.

  • Patent number: 10730282
    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.

  • Publication number: 20190291349
    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.
