3D打印技术在图学模型中的应用研究

Research on the Application of 3D Printing Technology in Graphic Model

利用光固化3D打印技术成型出各种几何体,将单元基本几何体模型表面磁化处理;利用磁学吸合特性可以直接实现几何体的组合连接功能要求,又保持了几何体表面的平面完整性要求,方便拆分,组装灵活,实现组合体不同形体形式的变换。但同时,光固化3D打印技术在组合模型的制作中也存在新的问题,例如打印出的模型出现变形以及去支撑后表面会留下痕迹等。通过工艺探究,为解决这两个问题提供了一些思路,提高了利用3D打印技术制作图学模型的质量。

Various geometries were formed by using the 3 D photo-curing printing technology,and the surface of the basic geometry model ofthe unit was magnetized.The magnetic absorption feature was used to directly realize the combination and connection function requirements ofgeometry body,and maintain the plane integrity requirements of geometry body surface,which was convenient for splitting,assembling andrealizing the transformation of different forms of the combination.However,there were also new problems in the production of compositemodels,such as deformation of the printed model and traces left on the supported surface.Through the process exploration,some ideas wereprovided for solving these two problems,and the quality of the model made by 3 D printing technology was improved.
