In the additive manufacturing (AM), thermo-mechanical, physical, and geometrical interface are very important factor to be considered, while manufacturing the product since it directly affects the flexibility and complexity of the object. A deep understanding is always necessary regarding the material behavior including viscosity during material deposition process to make sure the structural design accuracy and the quality of the end product. The material section is crucial stage in AM work. Achieving precision and intricate detailing in AM parts hinges on precise control of resolution and deposition accuracy is important. Additionally, for improving the mechanical properties along with design accuracy, a post-processing techniques incorporation can be useful. Thus, it is very important to consider the melting, solidification, and shrinkage phenomenon as well as controlling the defects in AM. A perfect temperature is necessary and making sure material’s temperature don't get too hot or cold is super important for keeping everything in good shape while AM 3D printing. If the temperature isn't right, it can mess up the final object and results to bend or break the product. When raw material gets heated up during printing, it will create extra stress which may affect the strength of the resulted object. Therefore, it's crucial to control and pick the right tools for heating and keep the temperature as per the necessity. Also, managing the uniform heat flow inside the printer is about to concern. Exploring out these factor, we can convert AM to make it work even better. The aim of this investigation is to explore the related factor which can be further optimize such as materials used, the shape of the object, and heat flow and control, viscosity control. We hope this research investigation would find several ways to make AM faster, economical, and less wasteful.
