3D打印的研究热点及其演化：基于科学知识图谱的分析

Hotspots and its Evolution of 3D Printing: an Analysis Based on Scientific Knowledge Map

摘要:

针对1995-2016年间SCI核心数据库中有关“3D打印”主题的2769条文献记录,借助CitespaceIII科学知识图谱软件,选用“聚类”、“标志性文献”、“突发文献”和“突现关键词”四大指标,综合性探索3D打印的研究热点及其演化过程,并展望未来的3D打印研究热点。研究发现：(1)3D打印的研究热点最早出现在1993年,从2005年开始迅猛增长,在2013年出现高峰；(2)热点主要集中在“医疗支架、器官与药品”、“快速成型”、“增材制造”和“化学合成反应”等领域,也出现在“超声波固化”、“激光烧结”和“金属基复合材料”等技术层面；(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)“增材制造”、“3D生物打印”、“钛合金”与“化学合成反应”等是近年来最新兴的研究热点；(5)“商业化运营”和“与大数据等新兴技术的融合”等有可能成为未来的研究热点。研究成果可以促进3D打印相关理论的发展,为科研人员确定3D打印领域的研究重点和方向提供参考,为企业掌握市场竞争主动权和政府规划3D打印产业发展提供借鉴。

Abstract:

Based on the indicators "cluster", "landmark article", "burst reference" and "burst Keywords", 2769 literatures searched from SCI core database in 1995-2016 about 3D printing theme were analyzed to explore the research hotspots and its evolution of 3D printing with the scientific knowledge mapping software CitespaceIII. The results show that: (1) hotspots appeared first in 1993, grow rapidly from 2005, and peaked in 2013; (2) hotspots mainly include "medical scaffold, organ and drug", "rapid prototyping", "additive manufacturing" and etc. also appeared in "ultrasonic consolidation ", "sintering" and "metal matrix composites " and other technical aspects; (3) the hotspots in "medical field" appeared the earliest, and remain extremely active; (4) "additive manufacturing", "3D bioprinting", Ti-6Al-4V technology such as big data" may be the hotspots in the future. The research can promote the theory development of 3D printing, help researchers to determine the research direction and focus on 3D printing, and provide a reference for enterprises and government to plan the industry development of 3D printing.
