The „European network for 3D printing of biomimetic mechatronic systems – 21- COP-0019 - EMERALD project, which is part of the Education, Scholarships, Apprenticeships, and Youth Entrepreneurship Programme (ESAYEP) under the EEA Grants 2014-2021, represents a collaborative effort between technical universities coming from Romania (Technical University of Cluj-Napoca and University Politehnica Bucharest), Norway (University of Agder), Poland (Poznan University of Technology), and one private company coming from Slovakia (Bizzcom). This project that is part of the "2021 Cooperation Projects in Higher Education Area," which was implemented in the period 2022-2023 has been focusing on providing educational tools concerning the development of biomimetic mechatronic systems for people with special needs (with amputated arms) by 3D printing technologies. The EMERALD consortium partners have tried to find adequate methods of integrating theoretical knowledge with practical application in the field of biomimetic mechatronic systems realized by 3D printing technologies for people with special needs (with amputated arms) in the end. This integration can be clearly seen in the EMERALD e-toolkit manual, a comprehensive guide that has been developed in order to bridge the gap between theoretical aspects shown in the e-book that comprise basic knowledge and theoretical information as basics for real practical applications, focused on the conceiving, manufacturing and testing of biomimetic mechatronic systems for people with special needs (with amputated arms), using 3D printing technologies. The e-toolkit manual which is the result of the collaborative creation of the EMERALD consortium partners serves as a detailed laboratory guide that goes beyond theoretical information, providing step-by-step instructions on how to design, manufacture and test biomimetic mechatronic systems realized by different types of 3D printing methods. The content of the e-toolkit manual is comprehensive, covering every essential stages in the development of such systems, beginning with the pre-validation of Computer Aided Design (CAD) models through Computer Aided Engineering (CAE) analyses, continuing with the selection of suitable materials for 3D printing, integrating of sensors and transducers and ending with programming, assembling, as well as the use of Virtual Reality / Augmented Reality applications being applied for these systems. A key goal of the e-toolkit manual is to encourage the practical application of theoretical concepts learned in the course modules provided in the e-book by engaging both professors and students to go one step forward in producing practical case studies of biomimetic mechatronic systems for people with amputated arms, guiding them through each developing stage with detailed instructions that are being offered on the e-toolkit manual. This hands-on approach not only enhances learning, but also stimulates creativity, prompting the design of new personalized biomimetic mechatronic solutions. These solutions incorporate innovative ideas in shape and material selection, customized to specific manufacturing settings and use of different 3D printing technologies for the producing of real practical biomimetic mechatronic systems to support real patients with amputated arms in the end.
