Abstract

The emergence of additive manufacturing (AM) technology for ceramic clay materials has greatly impacted the traditional pottery manufacturing industry. However, there are still limitations in post-processing and structural design for ceramic clay materials in the current field. To address these challenges, in this study, we first used orthogonal experiments to investigate the impact of the heating rate during debinding, the final sintering point, and the insulation time at the sintering point on the performance of the fabricated parts. It was further concluded that the optimal debinding sintering strategy consisted of a debinding heating rate of 0.5 °C/min, a final sintering point of 1300 °C, and a sintering point insulation time of 3 h. Under these conditions, the compressive strength of the specimens reached a maximum of 38.75 ± 4.57 MPa. Herein, we accomplished the printing of two different structures based on liquid deposition molding (LDM) technology. Through comparative analysis of the experimental results, the research solved the buckling phenomenon of flexural specimens and concluded that the octet structure exhibited superior performance. Additionally, we successfully prepared various pottery specimens, further demonstrating this study's application prospects.
