The study presents a rapid manufacturing approach to fabricate a new class of topological ordered copper graphene foams (TOCGF) using combination of ultrasonic assisted pressureless sintering and 3D printing. The ultrasonic vibrations homogenously well dispersed the low-density graphene in the metal matrix. The relative density of the TOCGF was decreased with respect to pure copper with increasing the concentration of graphene. The compressive properties of the TOCGF were enhanced up to 1% graphene addition but decreased with further addition. (C) 2019 Published by Elsevier B.V.
