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.
