Enhancing isotropy in PLA FDM printed parts through optimized G-code for improved layer adhesion

Fused Deposition Modeling has revolutionized the manufacturing world and it is now the most used technology for 3D printing. However, FDM is hindered by anisotropy, where mechanical characteristics are different. Though geometry and size are very influential in this issue, there is one thing that has an immense impact: the filament deposition pattern. This phenomenon affects all FDM printed parts, presenting challenges in terms of their strength. This is the primary objective that this research pursues. Identifying the optimal infill pattern has the main goal of incrementing the strength of the layers so that their mechanical response is similar in every direction. This means that the workpieces can be made and used in all directions, without the risk of the piece breaking due to the little adherence between layers. This research paves the way for the use of FDM machines to create products with uniform resistance.
