Abstract Scope |
Additive manufacturing is a rapidly growing process in which parts can be created layer-by-layer, resulting in less waste. This process produces parts whose properties depend on the direction in which the parts are made. Because of the layer-by-layer process of manufacturing parts, different properties can occur in various directions of manufacture, often called anisotropy. These properties can be attributed to different manufacturing parameters, such as infill density and raster angle. This study aims to study and predict the anisotropic properties of Polyethylene Terephthalate Glycol (PETG) tensile specimens created using material extrusion and tested according to ASTM standards, which are internationally recognized standards for testing and materials. To accomplish this, physical studies, as well as computer-aided simulations, will be performed to understand how changing the infill density and raster angle affects the finished product. The impact will be invaluable to better predict how additively manufactured PETG parts behave under tensile loads. |
