Parametric numerical model for predicting mechanical properties of structures made with FDM technology from polymeric materials
Abstract
This article presents a new numerical model for predicting the mechanical properties of the structures produced using Fused Deposition Modeling (FDM) technology. The model implemented in the finite element method represents internal structure of the investigated material, generated based on manufacturing parameters such as layer height, raster spacing or orientation of subsequent layers. In addition to numerical analysis, the experimental investigation of the samples made of ABS-M30 (Stratasys Ltd.) were performed and longitudinal elasticity modules in three directions were determined and compared with the results obtained from the numerical model. Differences in experimental and numerical values of longitudinal modules ranged from 0.79 % to 6.19 % depending on the load direction. Such low error values allow to state that the presented model is suitable for estimating the stiffness of the components manufactured by Fused Deposition Modeling.
