Silicon carbide (SiC) materials are widely used in various fields, including national defense, aerospace, energy, and environmental protection owing to its excellent properties such as lightweight, high-strength, and excellentthermal-stability. However, SiC ceramics face a challenge due to the mutually restrictive relationship between their irregular structure and formability. While traditional manufacturing methods can produce high-performance SiC ceramic parts, forming complex structures remains difficult. On the other hand, additive manufacturing is capable of creating intricate designs, but integrating high strength and toughness into SiC-based ceramics through this method poses significant challenges. Therefore, researching additive manufacturing techniques for SiC structural ceramics that offer high precision, strength, and toughness is of great importance. This paper systematically summarizes the SiC-based ceramics produced by current additive manufacturing methods. It analyzes and discusses SiC-based ceramics reinforced through continuous fibers, short-cut fibers/whiskers, and sandwich structure toughening techniques. Based on the current research status, the article also outlines future development trends, providing valuable insights for advancing high-precision, high-strength, and tough additive manufacturing of large-scale, complex SiC-based ceramic components.
