Effect of Infill Struktureon Mechanical Parameters of FDM 3D Printed PLA and PLA+CF Materials: Characterization and Comparative Analysis

This scientific article investigates the impact of different infill structures on the mechanical parameters of Fused Deposition Modeling (FDM) 3D printed materials, specifically polylactic acid (PLA) and polylactic acid reinforced with carbon fibers (PLA+CF). The study involves a comprehensive characterization and comparative analysis of tensile strength, nominal strain at break, and other key mechanical properties. Through a systematic approach, the research aims to provide insights into optimizing the infill structure for enhanced performance and usability of 3D printed products. The comparative analysis includes a detailed examination of PLA and PLA+CF materials, highlighting their distinct mechanical behaviours under varying infill structures. The findings contribute to a deeper understanding of the interplay between infill design and mechanical properties, facilitating advancements in the field of additive manufacturing.
