Abstract: An additive manufacturing method and system for printing a three-dimensional part, which includes generating a magnetic field in a build chamber, printing layers of the three-dimensional part in the build chamber, and transferring layers of a magnetic support media to the build chamber in coordination with the printing of the layers of the three-dimensional part. The method also includes magnetically coupling the transferred layers of the magnetic support media in the build chamber with the generated magnetic field to produce a self-supporting bed of the magnetically-coupled media.

Abstract: The deposition of graphene is accomplished by various techniques that result in a change of the graphene's solubility in the liquid medium. The solubility change enables the deposition of the graphene onto the substrate. Once the graphene is deposited onto the substrate, the at least partially coated substrate may be separated from the liquid medium. The substrates may then serve as a carrier to deliver the graphene to a desired application.
