3D PRINTER AGGT

The Reality Ender 3 is a cost-effective fused deposition modelling (FDM) 3D printer that has gained significant popularity due to its open-source nature and upgrade flexibility. This study presents the systematic enhancement of the Ender 3 platform through a series of hardware and firmware modifications aimed at improving printing performance and operational stability. The implemented upgrades include an all-metal hot end for high-temperature printing, a CR Touch-based automatic bed levelling system, silent stepper motor drivers for noise reduction, and optimized part cooling solutions. Structural reinforcements and firmware tuning were also carried out to enhance motion accuracy and thermal consistency. Performance evaluation was conducted based on parameters such as dimensional accuracy, surface finish, print speed, and acoustic emission. The upgraded configuration demonstrated measurable improvements across all evaluated metrics when compared to the stock printer. The findings of this study emphasize the effectiveness of targeted upgrades in transforming an entry-level 3D printer into a high-performance prototyping system suitable for both educational and semi-professional applications.
