摘要
熔融沉积成型(FDM)以其成本低、操作简易、适用性广、可靠性强等优点成为应用最为广泛的3D打印技术之一,在汽车、航空航天、医疗等多个领域受到广泛关注。对FDM领域专利申请情况进行统计和分析,重点从专利申请趋势、专利布局区域、专利申请人、专利技术主题等维度全面展示了该领域的专利布局情况。结果表明:我国FDM专利申请量自2011年开始快速增长,目前已成为该领域专利申请量最多的国家,但海外专利申请量相对于欧美国家偏少;FDM专利的各技术分类中,成型设备专利申请量自2015年开始快速增长,逐渐成为专利数量最多的技术分类,创新主要集中在喷头、送料机构、运动机构和加热原件等部件中;通过对比全球主要专利申请人的专利技术特点,建议我国FDM领域创新主体加大在数据处理和成型材料方面的研发投入,加强产学研合作和海外市场专利布局,构建具有行业领先优势的高价值专利组合。
Fused deposition modeling(FDM)has become one of the most widely used 3D printing technologies,due to its advantages such as low cost,ease of operation,wide applicability,and strong reliability.It has attracted increasing attention and research in various fields including automobile,aerospace,and medical applications.Patent applications of FDM are analyzed,focusing on patent application trends,patent layout areas,patent applicants and technology themes,providing a comprehensive overview of patent layout in this field.The results indicate that China’s FDM patent applications have been rapidly increasing since 2011,making it the country with the highest number of patent applications in this field.However,the number of overseas patent applications is relatively low compared to that of European and American countries.Among the various technical classifications of FDM patents,the number of patents related to modeling equipment has been rapidly increasing since 2015,gradually becoming the most prevalent technology classification.Innovations in FDM equipment are primarily concentrated on components such as nozzles,feeding mechanisms,motion mechanisms and heating elements.After comparing the technical characteristics of major global applicants,it is recommended that China’s innovators in the FDM field increase their R&D investments in data processing and materials.Additionally,it is crucial to strengthen industry-university-research cooperation and patent layouts in overseas markets with the aim of establishing high-value patent portfolios that offer industry-leading advantages.
