Abstract: The present disclosure is directed, in part, to method for selective thermoplastic electrophotographic process additive manufacturing, the method comprising applying a high-absorbance support material and a low-absorbance part material adjacent to one another: applying radiated energy to the high-absorbance support material and low-absorbance part material such that the high-absorbance support material selectively absorbs the radiated energy and transfers heat to the low-absorbance part material.
