Abstract
Additive manufacturing technology can quickly manufacture parts with dense microstructures and excellent mechanical properties, so that it shows a broad application prospect in aerospace and other fields. Additive manufacturing technology was briefly introduced in this paper. On this basis, the technology and characteristics of metal powder and wire additive manufacturing were systematically analyzed and compared, and the development of additive manufacturing technology was prospected.

Compared with the p ast machining method s o f cutting and assemb ling raw materi als, it is a manufacturing method in wh ich materials are sup erimposed from manufacturing, and expou nds the research status of metal powder and wire additive manufacturing technology
Th e forming quality of metal powd er additive is high, which is especially suitable for t he production of precision small p arts
Summary
Additive manufactu ring k nown as 3D p rinting, is a technology that combines subjects suc h as materials science and computer aided design. Metal powder additive manufacturing technology beam to melt th e metal powd er, th en it fo rms p arts through c ooling an d s olidification p rocess It has t he characteristics of no binder, high f orming p recision and good mecha nical properties. Th e forming quality of metal powd er additive is high, which is especially suitable for t he production of precision small p arts. Ho wever, it h as h igher requ irements on th e equipment an d e nvironment of p owder m anufacturing. The cost of powder manufacturing is higher than that of silk, but the efficiency is lower
