In this article, a powder-bed class of additive manufacturing (AM) is incorporated into the manufacturing of graphene nanocomposite 3D structures. For AM of graphene-based 3D structures, graphene oxide (GO)/hydroxyapatite (Hap) nanocomposite (GHN) was synthesized at different GO to Hap percentage (wt.%), including 0.2% and 0.4% to develop a printable powder. The synthesized powder was utilized in a powder-bed AM system to fabricate 3D porous structures of GHN powder. It was shown that at layer thickness of 125 mu m and core binder saturation level of 400%, the compressive mechanical strength of the samples with higher content of graphene was improved significantly.
