    摘要： A system is provided for processing slice data representing a slice of a three-dimensional object to be generated by an additive manufacturing system. The system includes a processor to perform, when the additive manufacturing system is to generate the slice, a transformation on the slice data based on characteristic data of the additive manufacturing system, the slice data derived from three-dimensional object design data.

    摘要： In one example, an apparatus for generating a three-dimensional object includes an energy source to apply energy to a layer of build material to cause a first portion of the layer to coalesce and solidify, an agent distributor to selectively deliver a cooling agent onto a second portion of the layer, and a controller to control the energy source to apply energy to the layer to cause the first portion to coalesce and solidify in a first pattern and to control the agent distributor to selectively deliver the cooling agent onto the second portion of the layer in a second pattern independent of the first pattern.

    摘要： According to examples, a build module may include a housing, a build material chamber, and a build chamber. The build material chamber may be positioned beneath the build chamber in the housing and may include a moveable support member, in which a build material distributor is to supply successive layers of build material onto the moveable support member from the build material chamber. The build module may be removably insertable into a build receiver of an additive manufacturing system to allow the additive manufacturing system to solidify a portion of the successive layers received onto the moveable support member during the solidification process of the build material. The moveable support member may separate the build material chamber from the build chamber to block build material from the above the build material chamber from being received into the build material chamber during a solidification process of the build material.

    摘要： In an example of a three-dimensional (3D) printing method, a build material (consisting of an inorganic particle and a polymer attached thereto) is applied. The polymer is a continuous coating having a thickness from about 3 nm to about 1500 nm, or nano-beads having an average diameter from about 3 nm to about 1500 nm. The build material is heated to a temperature from about 5° C. to about 50° C. below the polymer's melting point. A coalescent dispersion (including a coalescent agent and inorganic nanoparticles) is selectively applied on a portion of the build material, and the applied build material and coalescent dispersion are exposed to electromagnetic radiation. The coalescent dispersion absorbs the electromagnetic radiation and heats up the portion of the build material in contact therewith to fuse the portion of the build material in contact with the coalescent dispersion and to form a layer of a 3D object.
