3D printing processes have found several applications in automobile, aerospace, and biomedical industries. Recent development of large-scale 3D printing processes has fueled applications in the construction industry. Materials such as ceramic clay (porcelain) can now be used in additive manufacturing (AM). However, information regarding the effect of process parameters on part quality is limited. There is a need to study the effects of various parameters on the successful printing of samples for the construction industry. This paper presents an experimental study to determine the feasible parameter regions for extrusion-based 3D printing of porcelain using a Delta WASP 2040 Clay printer. The printing parameters studied are extruder height, layer thickness, print speed and air pressure. The effects of these parameters on the surface quality of the printed samples are examined. The identified feasible parameter regions from this study would provide preliminary insights on material extrusion-based 3D printing of porcelain.
