The here proposed DIMAP project focuses on the development of novel ink materials for 3D multi-material printing by PolyJet technology. We will advance the state-of-the art of AM through modifications of their fundamental material properties by mainly using nanoscale material enhanced inks. This widens the range of current available AM materials and implements functionalities in final objects. Therefore applications will not be limited to rapid prototyping but can be used directly in production processes. DIMAP will show this transition in two selected application fields: the production soft robotic arms/joints and customized luminaires. In order to cope with these new material classes the existing PolyJet technology is further developed and therefore improved. The DIMAP project targets at the following objectives: additive manufactured joints, additive manufactured luminaires, ceramic enhanced materials, electrically conducting materials, light-weight polymeric materials, high-strength polymeric materials, novel multi-material 3D-printer and safe by design. With the development of novel ink materials based on nanotechnology improvement of the mechanical properties (ceramic enhanced and high-strength polymeric inks), the electrical conductivity (metal enhanced inks) and the weightiness (light weight polymeric materials) are achieved. Based on the voxel printing by PolyJet these new materials lead to a huge broadening of the range of available digital material combinations. Further focus points during the material and printer development are safe by design approaches, work place safety, risk assessment, collaboration with EU safety cluster and life cycle assessment. An established roadmap at the end of project enables the identification of future development needs in related fields order to allow Europe also in the future to compete at the forefront of the additive manufacturing revolution.

The European industry in the 21st century is facing the major challenge of responding to the needs created by the profound society changes of the past decades. Simultaneously it must increase its global competitiveness while creating more sustainability, wealth and jobs in Europe. Whilst the European excellence in fundamental research is widely acknowledged, the clear mechanisms for transfer of knowledge into innovative, high value industrial products are yet to be clearly understood and identified. Manufacturing plays a critical role in the value chain addressing societal needs and Grand Challenges. Specifically, high value manufacturing is significantly impacted by the successful integration of KEY ENABLING TECHNOLOGIES in this value chain. Future successful manufacturing that is adding value to the European Society will increasingly depend on the level of integration of Key Enabling Technologies. KETs are considered as: Essential to achieve globally competitive and sustainable EU manufacturing industry, Providers of an important social return on investments by significantly impacting manufacturing by boosting quality jobs creation. They are strategic in the generation of high value all along many value chains of classic or new industrial sectors in Europe (from materials, equipment and devices, to products and services), The EU KNIGHTS project aims to enable strategic integration of key enabling technologies, by promoting best practices, highlighting barriers and identifying appropriate business models/strategies to stimulate innovation with the goal of maintaining a globally competitive and sustainable European Manufacturing industry. The approach will include a comprehensive study of KETs across relevant industrial sectors with the objective to formulate guidelines and recommendations for effective, cross-sectorial KETs integration strategies, and for accelerated industrial innovation in addressing key societal goals and economic and social challenges.

The RobustPlaNet project aims at developing an innovative technology-based business approach that will drastically change the current rigid supply chain mechanisms and the current product-based business models into collaborative and robust production networks able to timely deliver innovative product-services in very dynamic and unpredictable, global environments. This technology-based business approach will allow distributed supply networks to efficiently deliver innovative product-services to customers with extremely high service levels (at least 95%) in global markets characterized by demand and variant turbulence, thus particularly exposed to worldwide disruptive (mainly economic) events. The development of this new business approach is based on four major pillars, namely (i) innovative supply services, (ii) innovative product-services enabled by ICT, (iii) innovative methodologies for decision-making integrating the plant and the supply network level and (iv) innovative business and assessment models for value creation based on partnership. The innovative services will include mechanisms for supply network coordination by production-related information- and risk-sharing contracts and predictive maintenance and equipment reconfiguration services for reliable plants. These services are provided by the equipment suppliers to the OEMs and component suppliers, whereas remanufacturing services are provided by the OEM and component supplier in the aftermarket. With the aim of developing a universal approach that can be integrated into different application domains, the feasibility will be demonstrated at machining and assembly processes in both inter- and intra-enterprise environments. In RobustPlaNet the demonstrations will apply the Navigation & Simulation Cockpit, the tool supporting decision makers on different levels of the plants and networks to react quickly and effectively to disturbances and uncertainties and keep the robustness of the overall network.
