| Abstract Scope |
Additive manufacturing (AM), especially fused deposition (FDM) modeling, has grown faster in recent years among industries and hobbyists. This growth is attributed to its many advantages, including low up-front manufacturing cost, a variety of materials that can be used, the best for quick prototyping, and the ability to manufacture parts with complex or complicated shapes. In this research, we focus on Polyethylene Terephthalate Glycol (PETG). Despite its precedence, materials used to manufacture parts through FDM have some unknown and unpredictable mechanical properties that result from the parameters chosen during the printing process. This study investigates the impact of the raster angle and infill density on the mechanical properties of PETG when subjected to an impact load. The infill density will be at 5%, 25%, 50%, 75%, and 100%. The raster angle will be at 0°-90°, 30°-60°, and 45°-45°. The experimental result will be compared to the FEA for better understanding. |
