Fused Deposition Modeling (FDM) 3D printing is one of the most widespread additive manufacturing technologies due to the accessibility of equipment, flexibility in material selection, and ease of use. However, insufficient part strength, particularly in the direction perpendicular to the printing layers, limits its application in load-bearing structures. This article presents a comprehensive analysis of the factors influencing the strength of FDM products and reviews modern methods of its enhancement: optimization of printing parameters, the use of reinforced filaments, moisture control, post-processing, as well as the application of automated systems for print parameter selection. Calculated dependencies, graphs, and experimental data are provided. The results of this study can be applied to improve the quality and reliability of FDM products in industrial production.

摘要

Fused Deposition Modeling (FDM) 3D printing is one of the most widespread additive manufacturing technologies due to the accessibility of equipment, flexibility in material selection, and ease of use. However, insufficient part strength, particularly in the direction perpendicular to the printing layers, limits its application in load-bearing structures. This article presents a comprehensive analysis of the factors influencing the strength of FDM products and reviews modern methods of its enhancement: optimization of printing parameters, the use of reinforced filaments, moisture control, post-processing, as well as the application of automated systems for print parameter selection. Calculated dependencies, graphs, and experimental data are provided. The results of this study can be applied to improve the quality and reliability of FDM products in industrial production.
