The application of graphic or functional elements to curved surfaces excludes individual solutions with conventional methods – for example using transfer films.
PROFACTOR’s solution – robot-assisted inkjet printing – combines expertise from robotics, nanotechnology (functionalization) and inkjet printing (functional inks, process development).
PROFACTOR has developed a series of printable inks and created the corresponding parameters for the processes, which allow to realize different properties and functionalities on geometrically arbitrary surfaces. For example:
- electrical circuits
- Haptics: digital materials
- Optical elements: Organic photovoltaic cells or LEDs
For optical elements that cannot be printed – such as holograms, for example – expertise from nanoimprint lithography (NIL) is used. PROFACTOR is currently developing methods to apply NIL on curved surfaces using robotics.
