Abstract: Due to having excellent technical characteristics, such as celerity and no limit to structure complexity, 3D printing technology is especially suitable for developing single piece, multi-variety and small batch electronic products, and for developing complex components with characteristics of electro-mechanical combination and functional structure, which are difficult to be realized by traditional manufacturing methods. The research of application of 3D printing technology in electronic products manufacturing has a great significance. Firstly, this paper introduces 3D printing technology and current development situation of its application in manufacturing electronic products. Then the development characteristics, tendency and needs of 3D printing technology for electronic products are analyzed. Finally, the appropriate approaches for the technical difficulties of multilayer PCB 3D printing are discussed.
