Water surface reinforcement effect in 3D printed polymer derived SiOC ceramics

In this work, PDC SiOC porous structures were fabricated using the stereolithography (SLA) 3D printing method with preceramic resin methylsiloxane. The printed structures were then sintered at 1000 °C for 1 h. Water treatment can help prevent the shrinkage and remove the unreacted resin. From the XRD and FT-IR results, the sintered ceramic is amorphous SiOC. The microstructures show that the printed structures have high geometric accuracy. The water reinforcement process produces smoother surfaces on the printed structures.
