Applications and research in 3D printing

In recent years, three-dimensional (3D) printing, an emerging manufacturing method, has garnered widespread attention due to its prototyping capabilities, low cost, and high flexibility. 3D printing has a profound impact on various fields, including industry, healthcare, education, aerospace, and engineering. This paper discusses three applications in 3D printing, future development, and their advantages and disadvantages. A detailed introduction to the principles and construction of 3D printing technology will be included. This paper will also present academic achievements and cases from the past 5 to 10 years. The research is conducted primarily through a literature-based analysis of recent scholarly studies and industrial case reports. However, studies have shown that the types and properties of materials are limited, a lack of production efficiency, and the difficulty in scaling up. 3D printing is accelerating the transformation to intelligence and personalized production. Future research should focus more on the material improvements, cost reduction, and integration with advanced technologies.
