Use Case »Smart Door«

Using the example of »Smart Door«, the project consortium shows how cables for operating elements, interior door lighting or electric motors in car doors are manufactured using printing and laser processes.

The exhibits show different conductor paths for large or small currents, which were produced using different processes such as inkjet printing, dispensing or a fully automated process for laying copper wire cables with an insulating sheath. Laser processes complement the processes and are used to prepare the substrates, to cure the inks or to functionalise electrically conductive pastes.  

Use Case »Smart Wing«

Using the example of »Smart Wing«, the project consortium shows that printable components such as temperature sensors, signal lines and contacts, wirelessly readable deformation elements, capacitive sensors or piezo impact sensors can be integrated in the printing technology of aircraft wings, for example.

In this process, electrical functional elements are printed directly on glass fibre or carbon fibre layers and then infiltrated with epoxy resins in a vacuum infusion process and processed into fibre-reinforced plastics and cured in an oven or with a laser.

Use Case »Smart Luminaire«

Using the example of »Smart Luminaire«, the project consortium shows how optically transparent bodies are produced using digital printing and laser processes. Specifically, lenses that project lettering or logos will be presented.  

Individualized optics, whose properties are similar to those of good optical glasses, were realized using an ink consisting of an optical hybrid polymer (ORMOCERE). In addition, a digital inkjet printing process can be used to create phase differences in optical bodies. The integration of conductor paths and LEDs in the optical bodies is also shown. The aerosol jet printing process is used for printing particularly small conductor paths. Finally, defined absorption areas were generated by laser to shade the scattered radiation of LEDs in a controlled manner.
