这项工作提出了半色调技术，用于为熔融沉积成型 (FDM) 打印机制造具有全灰度图像外观的 3D 对象。虽然基于液滴的抖动是一种常见的半色调技术，但这不适用于 FDM 打印，因为 FDM 通过在半连续路径中挤出材料来构建对象。提出了一组三种方法，将称为“阴影”的线性半色调原理应用于水平、垂直和对角线表面。与其他半色调方法相比，这些方法更适合 FDM：它们的适用性与几何形状和表面坡度无关，并且感知的色调对视角不太敏感。此外，这些方法对打印时间影响很小。双喷嘴 FDM 打印机的实验显示出有希望的结果。未来的工作需要优化所提出的方法之间的交互。
This work presents halftoning techniques to manufacture 3D objects with the appearance of full grayscale imagery for Fused Deposition Modeling (FDM) printers. While droplet-based dithering is a common halftoning technique, this is not applicable to FDM printing, since FDM builds up objects by extruding material in semicontinuous paths. A set of three methods is presented which apply a linear halftoning principle called 'hatching' to horizontal, vertical and diagonal surfaces. These methods are better suited to FDM compared to other halftoning methods: their applicability stands irrespective of the geometry and surface slope and the perceived tone is less sensitive to the viewing angle. Furthermore, the methods have little effect on printing time. Experiments on a dual-nozzle FDM printer show promising results. Future work is required to optimize the interaction between the presented methods.
