摘 要
本文概述了三维打印技术及其在复杂零件制造中的应用和挑战。作为增材制造技术，三维打印通过逐层堆积材料构建三维实体，包括光固化、FDM和SLS等多种类型。这些技术提高了设计自由度，支持多材料打印，缩短了产品设计到原型的周期，并促进了个性化定制。但其在复杂零件制造中面临技术成熟度不足、精度和一致性问题，影响产品质量和可靠性。材料种类有限和生产效率低也增加了成本。市场接受度有限是另一个制约因素。为应对挑战，建议增加研发投入，提高技术成熟度，引入高精度设备提升打印精度和一致性，拓展材料种类和引入高效设备以提升生产效率，加强宣传推广以提高市场认知度和接受度。

APPLICATION OF 3 D PRINTING IN COMPLEX PARTS
ABSTRACT
This paper provides an overview of 3 D printing technology and its applications and challenges in manufacturing complex parts. As an additive manufacturing technology, 3 D printing builds 3 D entities layer by layer, including various types of light curing, FDM and SLS. These technologies improve the design freedom, support multi-material printing, shorten the cycle from product design to prototype, and promote personalized customization. However, it faces the problems of insufficient technical maturity, accuracy and consistency in the manufacturing of complex parts, which affects the product quality and reliability. Limited material types and low production efficiency also increase costs. Limited market acceptance is another constraint. In order to cope with the challenges, it is suggested to increase investment in research and development, improve technology maturity, introduce high-precision equipment to improve printing accuracy and consistency, expand the types of materials and introduce efficient equipment to improve production efficiency, and strengthen publicity and promotion to improve market awareness and acceptance.
