This study aimed at the detailed bibliometric analysis (BA) of fused deposition modeling (FDM) to understand the trend and research area. Web of Science database was used for extracting data using keywords, and 2793 documents were analyzed. From the analysis, the most influential and productive authors, countries, sources, and so on were identified and corresponding interrelations were represented by a three-field plot. Lotka's law was derived for author productivity and its reliability was verified by the Kolmogorov–Smirnov (K–S) test. Bradford's law was used for identifying the core sources contributing to the field of FDM. From the trend topic analysis, it was found that initially the research was focused upon removing error related to deposition as well as part orientation, but with the course of time, it diversified to include topics such as optimization of printing parameters, materials, and applications. Based on the inferences from BA, the article also discusses on current research trend and highlights certain future areas for research work.

基于文献计量分析的熔融沉积建模 3D 打印方法回顾 (1994–2020)

本研究旨在对熔融沉积建模 (FDM) 进行详细的文献计量分析 (BA)，以了解趋势和研究领域。使用Web of Science数据库进行关键词提取数据，分析2793篇文献。通过分析，确定了最具影响力和生产力的作者、国家、来源等，并用三场图表示了相应的相互关系。Lotka 定律是针对作者生产力推导出来的，其可靠性通过 Kolmogorov-Smirnov (K-S) 检验得到验证。Bradford 定律用于确定对 FDM 领域有贡献的核心来源。从趋势话题分析发现，最初的研究重点是去除沉积和零件方向相关的误差，但随着时间的推移，它多样化，包括优化打印参数、材料和应用等主题。基于 BA 的推论，本文还讨论了当前的研究趋势，并强调了某些未来的研究工作领域。
