在本文中，一种非传统的增材制造方式--曲面分层打印，已经被应用到大规模的建筑过程中。尽管在过去的十年中，曲面分层熔融沉积模型（CLFDM）的研究工作的数量，很少有实际应用的报道。采用CLFDM原理的另一种方法是使用一个名为Grasshopper的脚本环境（Rhinoceros（R）的插件）开发的，该方法生成一个弯曲的分层打印路径。该方法使用拉夫堡大学开发的3D混凝土打印工艺进行了评估。包括模拟和印刷结果的方法的评估显示，与现有的平面分层印刷路径相比，这是特别有利于大规模AM技术的三个主要优点：（i）更好的表面质量，（ii）更短的印刷时间和（iii）更高的表面强度。(C)© 2016 Elsevier B.

In this paper, a non-conventional way of additive manufacturing, curved-layered printing, has been applied to large-scale construction process. Despite the number of research works on Curved Layered Fused Deposition Modelling (CLFDM) over the last decade, few practical applications have been reported. An alternative method adopting the CLFDM principle, that generates a curved-layered printing path, was developed using a single scripting environment called Grasshopper - a plugin of Rhinoceros (R). The method was evaluated with the 3D Concrete Printing process developed at Loughborough University. The evaluation of the method including the results of simulation and printing revealed three principal benefits compared with existing flat-layered printing paths, which are particularly beneficial to large-scale AM techniques: (i) better surface quality, (ii) shorter printing time and (iii) higher surface strengths.
