Abstract: In example implementations, an apparatus includes a storage unit, an auger screw, a housing enclosing the auger screw and at least one heater coupled to the housing. The auger screw receives a build material from the storage unit and delivers the build material to a build platform via movement of the auger screw. The build material is heated by the at least one heater as the build material is being moved by the auger screw.

Abstract: A transport device (106) includes a first volume (110) to receive a build material and a second volume (108) to contain an object created by an additive manufacturing system (100). The transport device (106) is receivable by a 3D printer (102) of the additive manufacturing system, and the 3D printer to build the object in the second volume. The transport device (106) is receivable by an extracting and supply device (104). The extracting and supply device is to extract the object from the second volume and to supply the build material to the first volume.

Abstract: A three-dimensional object may be generated. Energy may be applied to a layer of build material to cause a first portion of the layer to coalesce and solidify in a first pattern. A cooling agent may be selectively delivered on a second portion of the layer of the build material to reduce a temperature of the second portion in a second pattern, the first and second patterns being independent of each other.
