摘    要:3D打印(增材制造)作为区别于传统去除型加工的新型制造技术,正以其简易的制造工艺、较低的生产成本和较短的研发周期,备受人们关注。目前,3D打印技术已经开始从研发阶段逐步向产业化发展,但是3D打印用金属粉末的成本及其性能成为制约该产业快速健康发展的瓶颈之一。3D打印用金属粉末需要满足高纯度、高球形度、细粒径和窄的粒径分布等要求。其制备方法主要有雾化法、等离子体法、旋转电极法、等离子熔丝法等。通过3D打印用金属粉末性能要求、制备方法、粉末性能对3D打印零件的成形效果影响等几个方面介绍国内外的一些研究进展,并提出目前3D打印用金属粉末制备所面临的问题。

关 键 词:3D打印  金属粉末  性能

Abstract:Different from traditional manufacturing,3D printing (additive manufacturing) is a new manufacturing technology with simplified manufacturing process,lower manufacturing costs and shorter development cycles. Nowadays,3D printing technology is no more confined in laboratory,but now much toward to industrialization. But the limited variety,mass production and performance of the metal powder specifically used for 3D printing have became a constraint to the fast and healthy development of the industry. Metal powders for 3D printing need to meet the requirements of high purity,high sphericity and narrow particle size distribution. Major manufacturing technology for 3D printing metal powders includes atomization,plasma,rotation electrode process,plasma wire atomizing technologies. The effects of powder requirements,preparation methods and powder properties on the forming effect of 3D printing parts were introduced. The existing problems in the preparation of metal powders for 3D printing were also discussed.
Keywords:3D printing  metal powder  property
