摘　　要：目的研究基于UV喷墨方法获得高质量的3D打印彩色外观。方法基于熔融沉积的成型方法,设计并加工不同打印层厚及倾斜角度的直角梯台模型,通过UV喷墨平台对模型表面进行标准色块着色处理,论述阶梯效应对喷墨着色涂层的影响机理,以及喷墨对于3D打印阶梯效应的修复作用,显微观察模型表面图像,并测量色块颜色的色度值。结果比较分析得出,打印层厚和倾斜角度导致的未着色条纹是影响3D打印模型表面喷墨着色效果的主要因素。结论通过UV白墨涂覆的方法可以修复阶梯效应,从而获得高质量的3D打印彩色外观。The work aims to study the high-quality 3 D printed color appearance obtained based on UV ink-jet system. Based on the FDM method, the right angle ladder models with different printing thicknesses and inclination angles were designed and processed. The model surface was subject to the standard coloring of color lump by UV inkjet platform. The mechanism of influence of the staircase effect on the inkjet coloring coating and the repair effect of the inkjet on the 3 D printing were discussed. The model surface image was subject to the microscopic observation and the chromatic value of the color lump was measured. Based on the comparative analysis, the uncolored stripes caused by the printing thickness and inclination angle were the main factors that affected the inkjet coloring effect on the 3 D printing model surface. The staircase effect can be repaired by UV white ink coating to obtain high-quality 3 D printed color appearance.
