功能梯度材料打印路径体素化的信息融合方法研究

Study on Information Fusion Methods of Printing Paths Voxel for Functionally Graded Materials

目前,功能梯度材料模型的构建方法尚未成熟,仍需要建立一种新的算法,将功能梯度材料的材料组分信息附加到路径规划中,以实现材料空间到几何空间的映射。以Visual Studio 2019为开发平台,利用OpenGL进行可视化分析;将打印路径体素化,对材料组分进行设计与计算,并映射至几何坐标中,构建出有连续梯度变化的目标模型;生成具有几何信息和材料信息的新型G代码,并用于功能梯度材料精准3D打印。结果表明:利用路径体素化的方法,可以精准控制材料模型的梯度变化。

At present,the construction method of functionally graded material model is not mature,and it is still necessary to establish a new algorithm to add the material composition of functionally graded material to path planning to realize the mapping from material space to geometric space.Visual Studio 2019 was used as the development platform and OpenGL for visual analysis.The printing path was voxelized,the material composition was designed and calculated,and mapped to geometric coordinates to construct a target model with continuous gradient variation.A new type of G-code with geometric information and material information was generated and used for accurate 3D printing of functionally graded materials.The results show that the gradient change of the material model can be accurately controlled by using the method of path voxel.
