In this study, an intelligent mechatronic integration system was developed for an eco-friendly silk reeling machine. The proposed system, termed an “environmentally intelligent silk reeling machine”, utilizes recycled plastics such as acrylonitrile butadiene styrene and polylactic acid to produce 3D printing filaments. Integrated sensing modules monitor key parameters including temperature, extrusion speed, and filament diameter in real time, enabling precise process control and consistent material quality. The system also features remote monitoring capabilities, allowing users to manage operational status and efficiency through networked sensing feedback. In response to the growing issue of plastic waste from mass-produced products, this design emphasizes both economic feasibility and environmental sustainability. By converting discarded plastic bottles and other waste materials into reusable 3D printing filaments, the system not only reduces environmental pollution but also lowers material costs, demonstrating a practical approach that combines smart sensing technology, mechanical innovation, and green manufacturing.
