摘要:

为了使运动文胸模杯更加合体舒适,探索了基于逆向工程对运动文胸模杯建模,运用3D打印技术制作模杯的方法,首先通过三维人体扫描仪扫描人台获取点云数据,再运用Geomagic Studio软件优化点云数据,构造胸部NURBS曲面,根据模杯款式及体表曲率,运用UG软件截取模杯轮廓并对截取曲面进行厚度设计,3D打印运动文胸模杯模型过程中,首先对创建的模型切片,再运用光固化原理对模型进行3D打印,最终制得3D打印运动文胸模杯。同时分析了3D打印运动文胸模杯内表面与人台体表曲面之间存在的误差,其中曲面重构平均偏差为0.01mm,3D打印机精度为0.03mm。结果表明,结合逆向工程,运用3D打印技术,可以生产出合体的模杯,实现女性运动文胸模杯的个性化定制。

Abstract:

In order to make sports bra cup more fit and comfortable, a method was explored for building the sports bra cup model based on reverse engineering and 3-D printing the model for making cups. Firstly, the 3-D body scanner was used to obtain the point cloud data by scanning body form, then Geomagic Studio software was used to optimize the point cloud data and construct breast's NURBS surface, UG software was used to intercept the cup outline according to the bra cup style and body surface curvature and design the thickness value for the intercepted surface. During 3-D sports bra cup model printing process, the model slice was firstly created, and then with the principle of light curing, the 3-D model was printed.  Finally 3-D printing sports bra cup was achieved. The error between the surface of the 3-D printing sports bra cup and the surface of the body form was also analyzed. The results show that the average deviation of the surface reconstruction is 0.01 mm, and the precision of the 3-D printer is 0.03 mm. The research indicates that using 3-D printing technology with reverse engineering can produce fit cups, achieve female sports bra cup customization.

Key words: 3-D printing, sports bra, bra cup, reverse engineering, point cloud data
