PoLaRoll Logo

The overall objective of PoLaRoll project is to substitute the lithography step in current etching processes by directly structuring the lacquer with the PoLaRoll laser micro machining unit. The PoLaRoll-module will replace the current masking process within a continuous lithography etching process for micro-structuring stainless steel reels. This will enable a flexible and cost efficient process consequently increasing significantly the productivity . The modular concept of the laser structuring system will allow the integration into several other applications in order to substitute masking processes or direct digital structuring. When looking along the value chain of laser manufacturing systems, the laser sources typically are the starting point and are integrated into downstream machines and processing systems. To position the next generation Roll-to-Roll manufacturing technology in the global market place, time to market is a key factor. The PoLaRoll results will help Europe stay competitive on the international market of laser micro machining and roll-to- roll machinery solutions providing:

- Improved competiveness of laser-based manufacturing industry (equipment and suppliers) and the end-user industry; •Improved competiveness and strengthened Europe's market position of laser-based manufacturing industry;

- More efficient, more flexible and higher throughput of individualised laser-based production. Further impacts can be associated to PoLaRoll project:

- Environmental impacts: the partial replacement of environmental unfriendly chemicals on the etching process chain currently used on the foil perforation by laser based machining will lead towards a greener manufacturing. The partial replacement of unfriendly chemicals will generate environmental impacts on the reduction of this production as well as on the reduction of its waste management, which represents a direct economical aspect as well.
