Abstract:

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 address 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 opinions were proposed for the enhancement of printing strength and speed.

Key words: fused deposition modeling, interlayer bonding, printing strength, module optimization, printing speed, injection printing
