Abstract Scope |
Additive manufacturing (AM) is a manufacturing method that fabricates parts in a layer-by-layer process. AM has gained popularity due to its inherent ability to create less material waste. However, the layer-by-layer manufacturing process generates parts with properties that are challenging to predict. This anisotropic nature is a result of the different directions in which parts can be manufactured, such as raster angle and infill density. To advance the understanding of this anisotropic nature, High Impact Polystyrene (HIPS) will be manufactured using material extrusion and tested in tension according to ASTM standards. In addition to the physical testing, computer-aided engineering simulations will also be conducted to compare the accuracy of simulations in predicting failure in HIPS specimens. The results of this research will provide engineers with a valuable tool for analyzing parts prior to manufacture, thereby enhancing the efficiency and reliability of the manufacturing process. |
