The Effects of FDM Printing Parameters on the Compression Properties of Polymethylmethacrylate (PMMA) using Finite Element Analysis

3D printing technology has become a favored alternative in fabricating parts due to its flexibility in product customization. Recently, an abundant number of studies have been conducted to improve the overall quality of the 3D printed parts. One of the essential qualities is to provide mechanical properties that fulfill the functionality of the final product. Thus, providing the best option in tailoring the mechanical properties of 3D printed parts is very useful. This paper investigates the effects of printing parameters on the mechanical properties of Polymethylmethacrylate (PMMA) using finite element analysis (FEA). Taguchi's 33 design-of-experiment methods were used to design the experiment for the following printing parameters: shell thickness, type of infill, and infill density. The compressive test was performed using Ansys software and the variables under study were strain and total deformation. The results obtained from the FEA simulation show that the strain and total deformation are mainly influenced by infill density, followed by the type of infill and shell thickness. It is deduced from the study that the optimum printing parameters with higher infill density (70%) and combination with triangular infill pattern able to hold the structure more rigidly, therefore providing more resistance against deformation. This study proposed a platform for determining the mechanical properties of 3D models for FDM printed parts using FEA analysis

Comparison study on mechanical properties of 3d printed pla and pla/aluminium composites using fused deposition modeling method

3D printing technology has been developed to produce prototype and end used parts. The demand is increasing recently making this technology a popular choice for the industry especially using fused deposition modeling (FDM) method. A common material used for this FDM technology is polylactic acid (PLA) as it is sustainable, low cost, and compatible with the system. However new PLA-based composites need to be developed with improved mechanical properties for specific applications. The need to study the mechanical properties and effect of printing parameters on the printed parts of different materials is essential to achieve the desired output. This study intends to apply Taguchi's design of experiment (DOE) method to compare the effect of printing parameters such as layer thickness, number of shell and printing speed on the tensile strength of PLA and PLA/Aluminium composite. The result shows that PLA exhibits better tensile performance compared to PLA/Aluminium composite. The ANOVA analysis also shows that increasing number of shells contribute to greater tensile strength for both materials
