Activity A4 will create new ideas from mutual inspiration among partners, led by UO who has developed design experience for 3D-printing. In comparison to established manufacturing, 3D-printing enables very innovative approaches for product design and functionality. Based on knowledge and awareness of technical opportunities and limitations from WP3 and of ecologic and economic assessment from WP2, new ideas for companies in the region will be developed. This includes ideas that promote a sustainable environment, that lead to more competitive or new products, or that enable new business models for SMEs. A catalogue of ideas at these three levels will result, serving as examples, as inspiration and ideally as best practice cases where 3D-printing was already implemented during the project. Promising ideas will be documented as idea concepts.
