Additive manufacturing of three-dimensional object

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.
