Abstract Scope |
A novel UV curable Mullite (SiO2-Al2O3) precursor is 3D printed via DLP (digital light process). The UV cured Mullite material is debinded and sintered (plain atmosphere) for achieving high material strength, thermal shock resistance, and structural stability, which can be a suitable candidate for high-temperature structural and thermal applications. The PDC (polymer-derived ceramic) process reaches 95% densification without compromising design flexibility and material performance. In addition, large-scale prototypes are printed concurrently with fine-resolution (25 um) for intricate design on the parts. The material's flexural strength, hardness, and thermal conductivity are obtained while materials characterization is investigated for determining the printed materials' structure-property relationships. This research allows manufacturers to advance their design with time-efficient and cost-effectiveness. |
