Graphene 3D Lab Demonstrates Filament Circuit Board Application

Graphene 3D Lab Inc. ( TSXV:GGG,OTCQB:GPHBF) released a video today showcasing the use of graphene filaments with a 3D printed three layer circuit board.
Dr. Jeff Casey from Rockfield Research Inc. was able to 3D print the circuit board directly in his facilities, using only Conductive Graphene Filament, standard filament, a dual-head 3D printer, and a few additional components.
