Abstract:

As a mainstream technology for 3D printing, fused deposition modeling (FDM) has been received a wide application range. However, the insufficient strength of printing parts and slow molding speed are still the bottleneck for its development. Therefore, the researchers at home and in foreign countries have conducted in⁃depth research on this issue. This article explored various ways to improve printing strength from the perspectives of optimizing printing parameters and improving interlayer bonding, material modification, and process innovation. Meanwhile, the paper also analyzed the key factors that affect the molding efficiency of FDM from the two aspects of improving the printing method and optimizing the printing equipment and proposed the corresponding improvement methods. Finally, the comprehensive applications for improving printing strength and printing rate through artificial intelligence from the perspectives of printing path optimization and quality inspection were summarized.

Key words: fused deposition modeling, molding efficiency, molding quality, artificial intelligence
