Abstract
As a critical component of advanced manufacturing, 3D printing technology has been increasingly applied in mechanical manufacturing in recent years. This study focuses on 3D printing technology to explore its potential and challenges in the manufacture of complex components, rapid prototyping development, and customized production. By analyzing the technological characteristics of 3D printing and its complementary and substitutive roles relative to traditional manufacturing methods, the study reveals its advantages in improving production efficiency, reducing costs, and optimizing product performance. A combination of literature review and case analysis was employed to systematically examine the specific application scenarios of mainstream 3D printing technologies, such as fused deposition modeling and selective laser sintering, in mechanical manufacturing. Experimental data were utilized to validate the improvements achieved by 3D printing in material utilization, processing accuracy, and production cycle. The findings indicate that 3D printing technology can significantly shorten the product development cycle, reduce costs for small-batch production, and provide new solutions for the design and manufacture of complex structural components. Furthermore, this study proposes a multi-material collaborative manufacturing fr amework based on 3D printing technology, offering theoretical support and technical pathways for achieving higher-performance mechanical components. The primary innovation of this research lies in integrating 3D printing technology with the practical needs of mechanical manufacturing, proposing a digital manufacturing strategy aimed at optimizing the design of complex components. This lays a foundation for promoting the in-depth application of 3D printing technology in industrial fields. The final conclusion demonstrates that 3D printing technology not only compensates for the limitations of traditional manufacturing methods but will also play a more significant role in future intelligent manufacturing systems.
