Comparison of traditional processing and additive manufacturing technologies in various performance aspects: a review

Additive manufacturing, also known as 3D printing, is a revolutionary manufacturing technology. This paper compares the differences between additive manufacturing technologies, such as Fused Deposition Modeling, Selective Laser Sintering, Selective Laser Melting, Stereolithography, Layered Object Manufacturing, and traditional manufacturing processes, such as subtractive and equal manufacturing. The paper mainly discusses the differences between laser additive manufacturing and traditional processing technology in processing principles and materials. The development status of metal alloys, polymer composites, ceramics, and concrete are introduced in the paper. The advantages of metal products manufactured by additive manufacturing technology in mechanical properties and microstructure evolution are highlighted. The paper also identifies the reasons limiting the development of additive manufacturing technology and proposes future prospects, providing a theoretical basis for future research on additive manufacturing technology.
