Antennas can be printed direct on plastic. This saves space and saves money as well. Not even the antenna can be printed; some PCB tracks can be printed as well. The enclosure can be used like a PCB. It can hold LEDs, buttons, connectors or whatever you like. Even a touch panel could be a part of your enclosure.
The nice is that this can be done close to my home. The machines that can do this amazing job are made in Germany and will be shipped to any corner on this planet. Nevertheless, some machines were not shipped and run in the region where I am living. I have access to this great source of technology easy.
