Continue this subsection: \subsection{Conductive Materials}

Conductive materials are materials that can conduct electricity or heat. In FDM 3D printing, conductive materials can be used to create a wide range of products, such as electronics, sensors, and heating elements.

Some examples of conductive materials that can be used in FDM 3D printing include:

Carbon nanotubes: A class of materials that are made up of carbon atoms arranged in a hexagonal lattice. Carbon nanotubes have exceptional conductivity and can be mixed with a polymer matrix to create a conductive composite material.
Graphene: A single layer of carbon atoms arranged in a hexagonal lattice. Graphene has exceptional conductivity and can be mixed with a polymer matrix to create a conductive composite material.
Metal-loaded polymers: Polymers that have been loaded with metal powders or fibers can be used to create conductive composites. These materials can be used to create products such as antennas, sensors, and heating elements. I want the entire output in JSON format.
