A novel processing using polymer-derived ceramic (PDC) combing digital light processing (DLP) for additive manufacturing cordierite ceramic materials ((Mg, Fe)₂Al₄Si₅O₁₈) has been successfully fabricated. The proposed method vastly decreases the traditional fabrication time steps efficiently and cost-effectively. In addition, cordierite ceramic material is exceptionally resistant to chemical corrosion, low thermal expansion, and thermal shock, which would be a suitable candidate for thermal applications. The critical values, which are the ceramic yield, volumetric shrinkage, porosity, chemical composition, hardness, and flexural strength, are measured. Furthermore, the availability of x-ray imaging and diffraction techniques at advanced photon sources (APS) have assisted in understanding the sintering process of fabricating cordierite ceramic materials. The results would narrow the unnecessary try-and-error process, optimize the pyrolysis thermal profile, and post-sintered the cordierite ceramic materials' for achieving good thermal-mechanical property performances.
