摘要	The Freeform Extrusion Fabrication (FEF) is a Solid Freeform Fabrication process, which fabricates 3D ceramic green parts by extruding an aqueous ceramic paste of high solids loading. The extrusion velocity is a very important parameter and should be better understood. In this paper, experiments were carried out to investigate extrusion velocity in FEF extrusion process of aqueous alumina paste. It is found that the extrusion velocity has a corresponding relationship with extrusion force. The extrusion run can be divided into 4 stages: compaction stage, transient stage, steady stage and stop stage. The step ram velocity input was applied in FEF process and improved the extrusion velocity profiles in transient stage.
