Additive manufacturing integrated Casting- A review

Integration of advanced manufacturing technology with traditional methods is a need for the current situation. Additive manufacturing technology is the most advanced manufacturing technology adopted by various industries. Foundry industries share a big percentage among the other manufacturing industries and are also capable to manufacture parts with complex geometry which are otherwise not possible or very difficult to produce with other manufacturing processes. Integration of additive manufacturing technology with the casting process can bring a new evolution in the foundry industry. The traditional casting process involves several complex and time-consuming steps, along with costly tooling. To make mold or core or pattern for small production is not an economical task. In this study casting manufactured by Additive manufacturing integrated casting is compared with conventional cast and comparison has been done based on dimensional accuracy, strength, time, surface roughness, and amount of material used. The main focus has been given to investment casting and sand mold casting as they are widely used for the production of cast parts. Moreover, challenges/limitations, current trends and future scope in additive manufacturing integrated casting have been discussed. This study helps the researcher to find a novel methodology to improve the capability of additive manufacturing integrated casting for various applications in the 21st century.
