摘要/Abstract

摘要： 近年来,随着3D打印技术的不断进步,彩色3D打印正成为行业的普遍需求。然而作为目前3D打印领域模型描述的标准文件格式,STL文件并不存储三维模型的颜色信息,无法满足彩色3D打印对模型信息提取和切片处理过程的新需求。在此背景下,选取OBJ彩色模型作为彩色切片技术的研究对象,解析其文件结构,提取其中保存的模型几何和颜色相关信息,并进行切片过程优化处理;结合OBJ模型的具体特点,在传统拓扑切片算法的基础上,提出基于模型连续性的彩色切片算法,给出了算法的整体流程步骤。应用该算法的切片处理提高了分层处理的效率,得到了模型的分层轮廓信息,完成了彩色切片的处理过程。实验结果证明该技术可对OBJ模型进行彩色切片处理,其效果良好,稳定可靠。

Abstract: In recent years,with the continuous progress of 3D printing technology,color 3D printing is becoming the general demand of the industry.However,as the standard file format of 3D printing field model description,STL file does not retain the color information of 3D model,which cannot meet the new requirements of color 3D printing for model information extraction and slice processing.In this context,the OBJ color model is selected as the research object of color slicing technology.Its file structure is analyzed,and the model geometry and color related information stored therein are extracted and optimized for slicing.Combined with the specific characteristics of OBJ model,the color slicing algorithm based on model continuity is proposed on the basis of traditional topological slicing algorithm,and the whole flow of the algorithm is given.The slice processing of the algorithm improves the efficiency of the layered processing,obtains the layered contour information of the model,and completes the processing of the color slice.The experimental results prove that the technology can perform color slice processing on the OBJ model with good effect,stability and reliability.
