| Abstract Scope |
Fused deposition modeling or commonly known as 3D printing is an additive manufacturing process (AM) which is gaining ground in today’s industry for its ability to create intricate shapes and designs faster and at lower cost than other processes. Considering the anisotropic nature of parts made through this process, predicting failure and understanding mechanical properties remains a challenge. This study aims to investigate the effect of infill density and raster angle on High Impact Polystyrene (HIPS) during impact loading. Infill density refers to the amount of materials in the internal structure, and raster angle is the angle between the layer orientation and the x axis. Using the ASTM D638, the specimens will be printed at 5%, 25%, 50%, 75%, and 100% infill density. The raster angle will be set at 0°-90°, 30°-60°, and 45°-45°. The experimental findings will be compared to the finite element analysis (FEA) results for better understanding. |
