摘要
选区激光熔化(SLM)技术是增材制造技术的一个重要分支。该方法基于离散/堆积原理,通过高能量的激光束熔化金属粉末的方式直接制备致密的三维块状材料。SLM技术在制备高精度的复杂结构零件、缩短生产周期和降低成本等方面展现出巨大优势,已被广泛用于各种合金材料的制备。综述了国内外采用SLM技术制备铝基、钛基、镍基及铁基材料的研究现状及其存在的问题,展望了SLM技术在未来金属材料制备领域的发展趋势。
Abstract
Selective laser melting (SLM) is regarded as one of the most important additive manufacturing technologies. Based on the principle of discrete stacking, a high-energy laser beam was used to melt metal powder. Subsequently, the dense three-dimensional bulk materials were formed directly via SLM. SLM has unique advantages in some aspects, such as production of complex parts, short processing time, and low cost, which has been widely used in the preparation of various alloy-based materials. This paper reviews the research status and the existing problems in producing aluminum-, titanium-, nickel-, and iron-based materials via SLM at home and abroad. The possible future research directions of SLM in the preparation of metallic materials are also prospected.
