Abstract: Some examples include an additive manufacturing system including a processor and a memory to store instructions. The instructions cause the processor to generate print data from received data related to a three-dimensional build object. The generated print data includes defined print data to dispensing a first agent at a build area of a build material layer, defined print data to selectively dispensing a second agent at a component receiving area within the build area of the build material layer, the second agent to locally reduce a viscosity of the build material at the component receiving area to a viscous state, and defined print data to position a component within the component receiving area at a time of the component receiving area being in a viscous state.

Abstract: The present disclosure relates to a method of three-dimensional (3D) printing a 3D printed object. The method comprises: selectively jetting a marking agent onto a first region of build material, wherein the build material comprises at least one meta and/or ceramic; selectively jetting a binding agent onto at least a portion of the build material; and binding the build material to form a layer; such that the marking agent is incorporated in the metal part in a predetermined arrangement that forms a detectable marker in the 3D printed object. The disclosure also relates to a multi-fluid inkjet kit for 3D printing.

Abstract: The present disclosure relates to a method of three-dimensional (3D) printing a 3D printed metal object. The method comprises selectively jetting an alloying agent onto build material. The build material comprises a first metal and the alloying agent comprises an alloying component that forms an alloy with the first metal. The method also comprises selectively jetting a binding agent onto the build material; binding the build material to form a layer: the alloying component is incorporated in the 3D object in a predetermined arrangement that comprises a first and a second region. The first region comprises the alloying component and the second region is substantially free from the alloying component or comprises the alloying component at a lower concentration than the first regions. The disclosure also relates to a kit that may be used in the method and a 3D printed structure that may be formed using the method.
