Many products often have insufficient functionality and quality for the corresponding application because the production of complex surfaces was previously not possible. In medical technology, for example, implants (e.g. silicone implants) are renewed monthly due to the biofilm formation by bacteria and surgically replaced. Glass or polymer lenses have poor optical transmission properties due to surface reflections. Nanostructures with antibacterial effect or nanostructures for reflection reduction (e.g. moth eyes) promise innovative solutions, which can also be economically applied to products.
Technologies
The solution „3D NIL“ now offers the possibility of applying micro- or nanostructures to curved and free-form surfaces. The technology used is based on UV-NIL with laboratory equipment specially developed for this manufacturing process. In addition to process development for the nanostructuring of different substrates using different material systems, PROFACTOR also offers the development and provision of prototype equipment.
Your advantages
- Full functionality even on freeform surfaces
- Anti-reflective surfaces or antibacterial effects
- Fast and cost-efficient application of the structures
- High flexibility of the process with regard to substrate, materials and structure sizes/shapes
Application areas
- Optical products: Lenses and lighting elements
- Medical devices: Implants, surfaces
- Consumer products: Displays, glasses, sensors

Micro- or Nanostructuring of large areas is often very time and cost-intensive. Roll-to-Plate UV-NIL now offers the possibility of providing surfaces with micro- or nanostructures over a large area and at high throughput. The technology is particularly suitable for the functionalization of rigid surfaces such as glass plates, plastic plates but also for thick films or very sensitive substrates.
The roll-to-plate NIL tool for micro- and nanostructuring in the clean room in the technology house of PROFACTOR is one of the first of its kind and was set up together with Stensborg A / S. It can be used for a broad range of structures ranging from sub-100 nanometers up to several 100 microns – and therefore for a broad variety of applications. For example: safety elements, microlenses, photovoltaic cells and even haptic or bactericidal structures for surfaces. It is also possible to print microfluidic structures, which are then filled with functional inkjet inks, for example for invisible switches on glass panels.
Your advantages
- Large area nanostructuring on rigid and also non-transparent substrates
- Combination of multiple material systems
- Digital material dispensing possible
- Multilayer nanoimprinting
Application areas
- Foils
- Displays
- Micro lenses
- Microfluidics
