Education
Industry: Widex (Denmark), for their invention of a computer-aided method to manufacture individually-fitted hearing-aid devices;
EPO's European Inventor Award 2012 goes to outstanding inventors from Germany, France, Denmark and Australia
The beauty of Rapid Manufacturing.
”The RM technology has given us a bigger creative designing space, because we
are no longer limited by a particular geometric shape.
We do not produce tools, which means that the production process is reduced to
a few weeks where it before took between 4 to 6 months.
The time factor means that we can now try out our ideas, and it gives us
an enormous amount of freedom”
Leif Johannsen, Chief Officer of Acoustics and Technology

Pumps and the world's electricity consumption
• Today pumps account for no less than 10% of the world's electricity consumption.
• Two third of all pumps use up to 60% too much energy.
• If every business switched to a high efficiency pump system there could be global savings of 4% of the total electricity consumption- comparable with the residential electricity consumption of 1 billion people

Graphene-based Thermoplastic Masterbatches for Conventional & Additive Manufacturing Processes
The NanoMaster Concept • Develop processes for large-scale rapid production of graphene, expanded graphite and
nano-graphite
• Develop machinery and processing methods designed for efficient, high-throughput production of masterbatches and compounds
• Develop material systems which can be incorporated into current conventional and additive manufacturing processes quickly, easily and safely.
• Reduce the amount of polymer required to produce components by 50%, whilst still meeting performance requirement
• Open up an extensive field of applications for plastic mouldings with significantly enhanced functionality
• For the first time, make industrial-scale quantities of graphene-filled compounds and masterbatches available to European industry
• Place European companies in a position to exploit the rapidly growing US and Asian markets
