Challenges and recent progress on the application of rapid sand casting for part production: a review

Abstract Conventional means of producing material via metal casting have long been used for centuries. In spite its advantages in durable parts with lower cost implications and the accommodation large part production, this conventional approach is still characterized by challenges high lead time patterns poor surface finish, need secondary manufacturing operations, which always leads to loss. Hence, introduction additive (AM) process has immensely recognized because huge negating some encountered route. However, inconsistency properties (such as density, strength, elastic modulus, dimensional accuracies, finish), produced one AM techniques (rapid sand casting), not yielding optimum results be applied high-tech application like aerospace automotive industries. Furthermore, technique lacks efficient qualification certification, contributes their disadvantages. This review focuses on recent progress from rapid moulds cores binder jetting (BJ), well incorporate certification future production casting.
