graphite heating element's purpose is to get hot, reliably and consis-tently, from element to element. When designing the manufacturing process for heating ele - ments, one has to think about electrical resistance. In the case of most other graphite components, a print and a material spec sheet would suffice in order to produce the components.

In the case of graphene, when the ions hit the surface at a high temperature, single layers of graphene are separated from the 3-D graphite structure. A centrifuge, which spins samples quickly to separate them based on density, can then be used to separate the remaining graphite from the graphene produced and ensure high purity.
