Abstract The chocolate 3D printing technology has been researched in this paper．We focus on the chocolate
continue filling and the printing accuracy，a high-precision chocolate 3D printer with continue filling system has
been designed．The Descartes coordinates system was applied in the injector controlling to improve the printing
accuracy．Moreover， a rolling screw was used instead of the piston in the extruding system to the keep the
continuous printing， and the heating system was added to the injector and the feeding box to control the
temperature of the chocolate．
