3D printing of clay is a new additive manufacturing (AM) technique that has emerged as a technology for manufacturing shapes with complex geometries like Fused Deposition Modelling (FDM) polymer 3D printing. The goal of this study is to evaluate the flowability and buildability of ceramic clay that is continuously extruded by varying printing speed, nozzle diameter and layer height to determine how the process parameters affect the quality of the ceramic clay layering and printing. The fundamental component of this research effort is Sayong clay which can only be found in Kuala Kangsar, Malaysia. The results showed that Sayong clay has been successfully 3D printed, which has its characteristics with optimized parameters. A density test was performed, and the results reveal that density decreases as the water content rises. As the diameter of the nozzle decreases, the diameter of the wall extruded from the nozzle decreases as well. Thus, the wall diameter will expand less after printing and the precision of the printing will be more accurate to the actual model. The layer height test shows that the thinner the layer height, the finer the quality of print which leads to lower yield of defects and fractures to the products.
