摘要
3D打印技术是一种新型的成型技术,其优点在于无需机械加工或任何模具,就可快速地将物体的数字化模型由概念变为实物,从而缩短产品的研制周期,提高生产效率。金属粉末作为金属3D打印最重要的原材料,其制备方法备受人们的关注。本文主要概述了雾化技术的基础原理,综述了气雾化用各类喷嘴结构、气体流场结构及工艺参数对粉末特性的影响,并对3D打印金属粉末制备技术的方法研究和最新进展进行了分析。
3D Printing technology is a new forming technology, it has some advantages:numerical model of object is change quickly from the concept into real without any machining or mold. It shortens the product development cycle and improves pro-duction efficiency. The metal powders is the most important raw material of 3D printing, its preparation method has attracted much attention. In this paper,a basic principle of the atomization technology is provided, the nozzle structures of gas atomiza-tion, effect of gas flow field structure and process parameters on the powder characteristics are all introduced,technology re-search and the latest advances in preparation of 3D printing metal powder are analyzed.
