Preparation of soluble ceramic cores via additive manufacturing technology: A review

• Additive manufacturing enables mold-free fabrication of complex soluble ceramic cores, reducing production time and cost. • Soluble ceramic cores, particularly water-soluble types, address the challenge of removing complex blind cavities in castings. • Various AM technologies (SL, SLS, DIW, BJ) have been successfully applied, each with distinct advantages and limitations. • Future developments focus on improving strength, surface quality, and expanding material options for soluble ceramic cores.
