  • Patent number: 11366454
    Abstract: In one example, a representation of a volume of a part to be printed by an additive manufacturing system is generated, where the representation depicts a plurality of voxels. A plurality of slices of the representation are generated. Each slice relates to a plurality of voxels within a first plane. A first process is performed in respect of a slice of the plurality of slices, wherein in the first process at least one voxel that has a predetermined colour and is located on a predetermined surface of the part is identified and a data file is updated to include data representative of the identified at least one voxel. The first process is repeated in respect of another slice. A three-dimensional preview of the part to be printed is generated based on the data file.

  • Publication number: 20220161498
    Abstract: In an example, a method includes receiving, at least one processor, object model data representing at least a portion of a first object that is to be generated by an additive manufacturing apparatus by fusing build material within a fabrication chamber. An indication of an amount of fused build material in a region of the fabrication chamber which is to be below the region in which the first object is to be generated may be determined and a dimensional compensation value to apply to the object model data representing the first object may be determined based on the determined indication. The determined dimensional compensation value may be applied to the object model data to derive modified object model data.

  • Publication number: 20220143915
    Abstract: Object model data modification is described in which object model data defining a first object to be generated by a three-dimensional printer may be obtained. A determination whether the first object is an object that may be adversely affected by a post-processing apparatus during post-processing based on a geometry of the first object to be generated can be made; and if the determination is affirmative, the object model data may be modified by adding a structure to the object model data to create a modified object comprising the first object and the structure, the modified object of a different geometry to the first object so as not to be adversely affected by the post-processing apparatus during the post-processing.

  • Publication number: 20220128970
    Abstract: In an example, a method includes receiving, by at least one processor, object model data describing a geometry of at least part of at least one object to be generated using additive manufacturing. The object model data defines a first geometrical transformation to be applied to the object model data. It may be determined if a second geometrical transformation is to be applied to the object model data. If a second geometrical transformation is to be applied, the first and second geometrical transformations may be applied to the object model data to determine modified object model data. Otherwise, the first geometrical transformation may be applied to the object geometry to determine modified object model data.
