  • Publication number: 20220080670
    Abstract: An example method of generating three-dimensional objects is disclosed. Object generation instructions to generate the object may be determined by defining a shell region of a layer of build material corresponding to the first portion of the object having a first color, and defining a fusing agent region on a layer of build material adjacent to the shell region on which fusing agent of a second color is to be applied and specifying an amount of colorant to be applied to the shell region wherein the object generation instructions specify application of fusing agent and colorant such that, when the layer of build material is heated using a heat source, the fusing agent region of the build material melts due to energy absorbed from the heat source and the build material of the shell region melts due, at least in part, to energy transfer from the fusing agent region.

  • Publication number: 20210394447
    Abstract: In one example a method of generating a three-dimensional object in a 3D printing system using a fusing agent of a first colour and a build material having a second colour different from the first colour, and a detailing agent, comprises obtaining object model data describing an object to be generated, and determining a first portion of the object to be generated to have the second colour. The method comprises determining object generation instructions to generate the object by defining a gap region of a layer of build material that is to correspond to the first portion of the object to have the second colour on which no agents are to be applied, a band of detailing agent on a layer of build material immediately adjacent to the gap region to define an outer limit of the gap region and therefore a boundary of the first portion of the object, and a fusing agent region on a layer of build material adjacent to the gap region on which fusing agent is to be applied.

  • Publication number: 20210101344
    Abstract: Certain examples relate to altering at least one control parameter of a printing process in an additive manufacturing system. In these examples following a change in operative state of at least one energy source at least one control parameter of a printing process is altered. An energy source is a device configured to apply energy to build material to facilitate the solidification of said build material. Control parameters determine the way a printing process is carried out. In some of these examples control parameters may be the irradiance of an energy source or the way in which the energy source moves over the build material to apply energy to the build material.
