Abstract

In the context of Industry 4.0, this study presents a defect-aware, closed-loop manufacturing system that integrates low-cost Internet of Things (IoT) devices with robotic automation to enhance quality control in 3D printing. A custom ESP32-based IoT device continuously monitors environmental and vibrational data to enable early defect detection during the printing process. If the predicted print quality falls below a configurable threshold (60%), the system halts the operation and instructs a UR3 robotic arm to remove the defective part - demonstrating full interoperability within a digital twin framework. The integrated machine learning model provides real-time feedback and autonomous control. More than 50 test scenarios confirmed the system's reliability, with latency remaining well within real-time operational limits. By reducing material waste and energy consumption, the proposed solution offers a scalable and sustainable approach to intelligent additive manufacturing.
