3D打印的研究热点及其演化:基于科学知识图谱的分析

Focuses and its Evolution of Three Dimensional Printing: Analysis Based on Scientific Knowledge Map

针对1995—2016年间SCI核心数据库中有关"3D打印"主题文献,选用聚类、标志性文献、突发文献和突现关键词等指标,综合性探索3D打印的研究热点及其演化过程。研究发现:(1)3D打印的研究热点最早出现在1993年,2005年开始迅猛增长,2013年出现高峰;(2)热点主要集中在医疗支架、超声波固化、激光烧结和金属基复合材料等领域;(3)医疗领域的相关研究出现最早,并且至今保持异常活跃;(4)3D生物打印、钛合金、化学合成反应等是近年来最新兴热点;(5)"商业化运营"和"与大数据等新兴技术的融合"等有望成为未来的研究热点。

Adopting the indicators of cluster, landmark article, burst reference and burst keywords, the related literatures searched from SCI core database in 1995-2016 about three dimensional printing theme were analyzed to explore the research focuses and its evolution of three dimensional printing. The results show that:(1) the research focus began in 1993, increased by leaps and bounds from 2005, and spiked in 2013;(2) the focuses mainly include medical scaffold, ultrasonic consolidation, sintering and metal matrix composites and other technical aspects;(3) the research in medical field appeared the earliest, and remain extremely active;(4) 3D bio-printing, Ti-6Al-4V and chemical synthesis reaction are the emerging focuses in recent years;(5) business operation and integration with big data and other emerging technologies may become a hot research topic in the future.
