This study aims to utilize silicon carbide (SiC) powder and phenol-formaldehyde resin (PF) as the primary raw materials to prepare phenol-formaldehyde coated silicon carbide composite (PCSC) using a thermal coating method. Then, single-factor experiment and orthogonal experiment were used to optimize the process parameters of selective laser sintering (SLS). Finally, SiC precursors were formed using optimized process parameters with excellent density and dimensional accuracies. The results show that the best combination of process parameters is: laser power of 25W, scanning speed of 1.7m/s, scanning spacing of 0.12mm and layer thickness of 0.16mm.
