Abstract
With the rapid development of science and technology, 3D printing technology, as an important part of modern manufacturing industry, is gradually transforming from prototype design to production and application. This technology enables the rapid fabrication of complex shape parts by accurately controlling the layered stacking of materials, with the advantages of high precision, high flexibility and low material waste. This paper summarizes the definition, principle and development process of 3D printing technology, and expounds how this cutting-edge technology moves from concept to practical application, and changes the pattern of traditional manufacturing industry. Focusing on the application of 3D printing technology in the design of complex parts, this paper discusses the basic principles of the design of complex parts, introduces a number of auxiliary design software, and shows how 3D printing helps the innovative design of complex parts through specific case analysis. The importance of design optimization and validation to ensure the feasibility and performance of the parts before manufacturing is also emphasized. This paper analyzes four challenges of 3D printing technology in complex parts manufacturing: the limitation of material selection limits the performance and use of manufacturing accuracy and surface quality affecting the final quality of parts, the slow manufacturing speed to meet the demand of mass production, and the cost efficiency, which makes 3D printing difficult to compete with traditional manufacturing technology in some applications. The corresponding improvement measures are proposed to meet the above challenges. Through expanding material research and development, develop more high-performance and low-cost materials, improve the control accuracy, and optimize printing parameters and processes to improve the surface quality and overall performance of parts; accelerate the printing process, introduce more efficient printing equipment and technology, shorten the production cycle, and reduce the operation cost and improve the economy and market competitiveness of 3D printing technology.
