Abstract: Combining with the existing feeding extrusion methods of extruders, a new 3D printing method for the blends of industrial ceramics-polymer was developed. According to the optimum mixing formula of industrial ceramics-polymer, the printing experiments were carried out with a self-designed new screw extrusion 3D printer. The four factors of feeding temperature, nozzle temperature, extrusion speed and forming platform temperature were taken as experimental variables. According to the orthogonal experiment, the blank of the experimental model was printed out. Finally, according to the surface accuracy and forming mass of the model blank, the optimum 3D printing process of blends of industrial ceramics-polymer was determined.

Key words: industrial ceramics, polymer, three dimpntional printing, forming process, orthogonal experiment
