Abstract In this paper, we present a Grasshopper plug-in that can be used to construct simulation files, designed specifically for 3D concrete printing applications. A custom Grasshopper component library was developed in C# using the RhinoCommon SDK. The component allows for the voxelization of any three-dimensional shape into a set of identical finite elements and produces ready-to-use Input files for simulation in Abaqus. The main contribution of this work is providing an extensive, yet easy-to-use plugin to be used by both non-experts (e.g. architects and designers that are familiar with the parametric toolbox that is provided by Grasshopper) and more advanced users (that can experiment with the broad range of input parameters in an attempt to optimize their 3D prints). The core component generates input (.INP) files based on state-of-the art numerical methods for simulation of concrete printing. The plug-in is made freely available for educational and academic use and can be downloaded from www.food4rhino.com/app/Concre3DLab .

VoxelPrint：用于基于体素的混凝土打印数值模拟的 Grasshopper 插件

摘要 在本文中，我们提出了一个 Grasshopper 插件，可用于构建模拟文件，专为 3D 混凝土打印应用而设计。自定义 Grasshopper 组件库是使用 RhinoCommon SDK 用 C# 开发的。该组件允许将任何三​​维形状体素化为一组相同的有限元，并生成即用型输入文件以在 Abaqus 中进行仿真。这项工作的主要贡献是提供了一个广泛但易于使用的插件，供非专家（例如熟悉 Grasshopper 提供的参数化工具箱的建筑师和设计师）和更高级的用户（即可以尝试使用广泛的输入参数来优化他们的 3D 打印）。核心组件生成输入 (. INP) 文件基于用于模拟混凝土印刷的最先进数值方法。该插件可免费用于教育和学术用途，并可从 www.food4rhino.com/app/Concre3DLab 下载。
