Summary: This study assessed the impact of Rapid Prototyping (RP) in the product development phase on the sustainability of a conventional supply chain. RP utilization was found to reduce assembly parts and material consumption, indirectly affecting waste generation, logistics, CO2 emissions, processes, and total costs. Increase in operational skills and knowledge in the social dimension was shown to reduce failure rates and improve product quality, highlighting the importance of training programs in enhancing social sustainability. The proposed generic model can help decision-makers accelerate RP adoption in supply chains and provide insights for operational decisions in product design stage.

Summary: The demand for more personalized products and shorter product life cycles has raised the bar for rapid establishment, commissioning, and operation of manufacturing systems. However, the complexity of traditional manufacturing system development processes often leads to longer delivery times. Small and micro enterprises may lack the necessary expertise to meet these evolving demands. Therefore, promoting turnkey projects under the Industry 4.0 paradigm is crucial in providing quick solutions for manufacturing system configuration and implementation.

Summary: A general theoretical analysis of a 3D generic TENG structure is presented in this paper. It is found that the optimal TENG geometry is independent of the frequency of the moving dielectric, but the external ohmic impedance for maximum power output is inversely proportional to the frequency. The energy of the TENG is proportional to the cube of its size, the square of the triboelectric charge density, and the angular frequency of the moving dielectric.
