NOVELTY - A material extrusion type three-dimensional printing involves (s1) preparing a supporting material and printing slurry, (s2) placing the supporting material into a container, and placing the container filled with the supporting material on a printing platform, (s3) supplying the printing slurry to the supporting material in the container, extruding by a three-dimensional printer based on a preset target design model, and (s4) determining a target curing treatment mode in the light transmittance of the supporting material, and curing the printing slurry in the target curing treatment mode to obtain a target model. The printing slurry is inorganic non-metal resin-based slurry or metal powder resin-based slurry, so that the printing slurry is suspended in the supporting material. The solid content of the printing slurry is ≥ 40%. USE - Material extrusion-type three-dimensional printing. ADVANTAGE - The method solves the poor performance of the printing material caused by the limitation of the existing material extrusion three-dimensional printing. The printing slurry is extruded and printed under the action of the supporting material, even if the printing slurry fluidity is high or difficult to solidify in time, the expected forming structure of the printing slurry can be well-kept under the action of the supporting material after extrusion, and has good fluidity of the printing slurry using resin as a base material.
