Additive manufacturing is a developing approach for producing complicated, difficult manufacturing objects. Fused deposition modeling is a manufacturing technique that works on a layer-by-layer basis that is widely utilized in industrial applications for quick prototyping in product design and development. The application of additive manufacturing technology allows the easy creation of complicated objects. Researcher have worked on infill patterns and infill percentages. Most of the research is based on experimental results with varying single process parameters. A study on infill patterns is an important aspect because it influences quality, material cost as well as production cost. In this research work, the simulations were carried out on the 50% and 70% infill rectangular and triangular patterns. It was found that, stresses generated in the triangular pattern are large compared to the rectangular pattern at the 50% infill and vice versa for 70% infill. For 50% infill, the triangular patterns are best suited for applications than the rectangular pattern, and for 70% infill, the rectangular patterns are best suited for applications than the triangular Pattern. © 2022
