Research on Color Control Method of FDM Full-Color 3D Printing
The traditional Fused Deposition Modeling(FDM)rapid prototyping manufacturing technology does not deliver mul-ticolor model processing due to the color unicity of the printing material.The direct RGB mixing method used in the existing"three-in-one-out"multichromatic apparatus,contributes to pronounced errors between the theoretical and the actual color,due to the difference of the color gamut space,the color deviation of the raw materials and the difference of the color mixing mecha-nism.In view of the color offset in the printing process,the proposed FDM color-mixing nozzle applies color gamut space conver-sion to establish the formula between color and FDMprinting technology.Based on linear fitting through experiments,the appara-tus builds a color-matching base oriented to multichromatic FDM 3D printing technology.It guarantees accurate transition from the designed model color to the actual printing color by matching the colors of models and a priori base colors.
