摘　　要：熔融沉积成型(FDM)技术以其低成本、易操作、快速原型制造和广泛适用性成为3D打印领域的主流技术。尽管FDM技术在3D打印领域具有重要地位,但其存在的一些局限性,如打印件的强度不足、成型速度缓慢等问题,仍然是制约该技术进一步发展的重要挑战。针对这些限制,本文从优化层间结合、材料性能强化两方面探讨了国内外学者在改善打印强度方面作出的努力,并从设备模块优化和优化打印策略(如注射打印)2个角度讨论了目前提高FDM设备打印速度的限制及改善措施;最后论述了对提升打印强度和速度的建议和意见。Fused deposition modeling(FDM)technology has become a mainstream technology in the 3D printing field due to its low cost,easy operation,rapid prototyping,and wide applicability.Despite its important position in the 3D printing field,there are still some limitations of FDM technology,such as insufficient strength of printed parts and slow molding speed.These have become the important challenges limiting the further development of this technology.To ad⁃dress these issues,this paper discussed the efforts of domestic and foreign researchers in improving printing strength from two aspects,i.e.,optimizing interface bonding methods and enhancing material properties.Meanwhile,the limitations and improvement measures for increasing the printing speed of FDM equipments were discussed from the perspectives of optimizing equipment modules and printing strategies(such as injection printing).Finally,some suggestions and opin⁃ions were proposed for the enhancement of printing strength and speed.
