    Designing a 3D printer
    Egbi, Daniel Bofa-Okim; Nemes, Dániel; DE--Műszaki Kar
    This thesis investigates the theoretical development of a 3D printer with exceptional accuracy, with a specific emphasis on virtual modelling, simulation, and optimisation methods. The suggested printer is designed to overcome the inherent difficulties of traditional 3D printing, with the goal of achieving unsurpassed precision in the creation of complex three-dimensional objects.The research commences by conducting a thorough examination of current 3D printing technologies, with the aim of identifying their constraints and potential areas for enhancement. Using sophisticated modelling tools, the thesis introduces an innovative conceptual design to improve accuracy and address typical printing problems.In addition, the conceptual design is situated within the wider scope of additive manufacturing, investigating potential uses in several sectors like medicine, aerospace, aviation, and mass customisation. The theoretical framework outlined in this thesis provides a roadmap for future academics and engineers aiming to transform these principles into physical technology.Ultimately, this research introduces an innovative and original blueprint for a 3D printer that achieves exceptional accuracy, thereby paving the way for progress in the field of additive manufacturing. The provided theoretical framework provides a clear plan for practical applications, hence creating new opportunities for precise engineering in three-dimensional printing.

    Lean Management, Additive Manufacturing and Sustainability
    Egbi, Daniel Bofa-Okim; Mátrai, Norbert Zoltán; DE--Műszaki Kar
    The twin phenomena of lean management and additive manufacturing (AM) are discussed together with their societal betterment role to realize sustainability and motivate of their integration in this direction. A major goal of lean management, waste and value-driven, is the optimizations of resources and the streamlining of different layers or processes. Using additive manufacturing, a process whereby parts are created layer by layer, a technique that facilitates previously unattainable functionality with minimal material waste. Using an extensive literature review supplemented with empirical investigation, this study explores synergies between lean practices and AM, identifying how their application together can yield far-reaching sustainability benefits. Synthesis of the findings reveal that companies that have embraced both frameworks have utilized less material, consumed less energy, and been more efficient. Additionally, the study highlights challenges like quality control issues in AM processes and cultural resistance to lean implementation that need to be overcome to achieve the potential benefits. This study does not only have theoretical contributions; it paves the way for further contributions towards recommendations for practitioners which are in the industry of Sustainable manufacturing. Framed in the wider context of literature, this thesis adds to the body of knowledge on manufacturing and sustainability and provides a path for further research in this space. In conclusion, the combination of lean management and additive manufacturing proffers a powerful approach to realize operational efficiency and environmental sustainability in manufacturing.
