摘要
在快速成型领域,STL已被公认为是一种使用相当广泛的标准零件描述文件格式。但是,STL文件格式无法保存三维模型的颜色等信息,所以该文件格式无法在彩色三维打印系统中用于传输数据。而VRML作为诸多现存文件格式中一种,可以有效地保存三维模型的颜色等信息。根据这一特点,采用VRML文件格式作为新的数据接口,通过提取VRML中的颜色等信息,对三维实体模型进行彩色切片;并利用实验室自行开发的彩色三维打印系统,成功打印出彩色三维模型。
In rapid prototyping area,STL file is acknowledged to be the standard file format which is widely used in model presentation.But it never includes color information when it' s used to describe 3D models.So it can' t be used for data transmission to realize color slicing in color 3D printing system.As one of those formats which can be used to store 3D models' information,VRML can store color information effectively.Based on this characteristic,this format was chosen as current data transmitting medium,color slicing was accomplished by extracting color information from VRML files.The results of color slicing were tested through laboratorydesigned 3D printing system,by which color 3D model was successfully printed.
