【摘要】 作为智能材料之一的磁流变液,是一种由软磁性颗粒、基液以及添加剂组成的悬浮液,在外加磁场作用下可形成有序结构,且该结构随外加磁场的变化而变化。而作为立体成像的关键元素——立体光栅,是一张由柱状透镜组成的特殊材料。由于水基磁流变液具有独特的磁流变效应、良好的流变性能和环境友好性能,将其运用到制作立体印刷光栅中,通过磁流变液的变化来控制软磁性颗粒的精确分布,从而达到印刷光栅所需的精度、透光性和稳定性,最终使光栅和立体图像覆合后呈现较好的立体效果。更多还原

【Abstract】 As one of the intelligent materials, Magnetorheological Fluid is dispersions composed of soft magnetic particles, carrier liquid and additives. The apparent yield strength of Magnetorheological Fluid can be changed significantly within milliseconds by the application of an external magnetic field. As the key elements of the three-dimensional imaging, the three-dimensional grating is a special material composed of cylindrical lens. Because water-based magnetorheological fluid has a unique magnetorheological effect, good rheological properties and environment-friendly performance, it is applied to the production of three-dimensional printing grating, through the change of the magnetorheological fluid to control the exact distribution of the soft magnetic particles, so as to achieve the desired accuracy, light transmittance and stability of printing raster, and finally present a ideal three-dimensional effect after laminating the grating and three-dimensional images.更多还原
