In order to compare the influence of the manufacturing methods on the property of silicone samples, the latticed structure of sample are designed, the silicone material is prepared and the silicone sample are produced by 3D printing and injection molding respectively. Four performance indexes of latticed silicone parts including the error of line width, the error of quality, tensile strength at break and elongation at break are proposed and measured. A fuzzy comprehensive evaluation system for evaluating the optimal forming method of the parts is provided. The performance indexes are used as evaluation factors, and the importance degree of the…
