Researchers from the Polish Institute of Electronic Materials Technology, together with Seco-Wawreick, developed a prototype able to produce a sheet of graphene with a surface area of 50x50 cm within four hours. It is considered to be one of the most efficient graphene producing equipment in the world.
This prototype is hoped to be able to undercut graphene market prices and allow large scale production. However, it is currently unavailable for commercial uses as it was financed by the National Centre for Research and Development. Some sources claim a similar machine will be commercially ready next year.
