Temperature and Humidity Control System to Address Filament Brittleness in 3D Printers

Additive manufacturing, mainly 3D printing, has emerged as a transformative technology with widespread applications across various industries. Despite its advancements, filament brittleness remains a significant challenge, undermining the quality and reliability of printed objects. In order to address this challenge, this study built a specialized temperature and humidity management system specifically for 3D printing applications. The system utilizes a Proportional-Integral-Derivative (PID) control technique to regulate the temperature within the filament storage environment, mitigating the impact of thermal fluctuations and moisture absorption. The system has been carefully developed and tested to assure optimal printing conditions, exceptional filament quality, and uniform print accuracy and precision. Since hardware testing confirms minimum disparities between sensor readings and reference measurements, reliability in environmental management is ensured for optimized print outcomes. Moreover, software testing ensures the PID controller's efficient functionality by providing real-time monitoring and control capabilities. Functional testing reveals the system's effectiveness in maintaining optimal storage conditions for various filament types, improving the quality of prints, and minimizing waste. Incorporating essential components such as sensors, actuators, and user interface elements guarantees seamless operation and intuitive engagement.
