面向3D打印机的活动关节快速生成方法

Rapid generation method of activated joint oriented to 3D printer

3D打印技术作为快速成型领域的新兴技术,成为一种迅猛发展的潮流,但3D打印机手工设计带有关节的模型繁琐耗时。文章提出一种基于用户交互的活动关节快速生成方法。首先通过交互式方法分割模型,获得模型的分割边界;然后利用实体建模库ACIS对提取的分割边界进行实体建模,生成活动关节的实体模型;最后网格化关节模型,并进行打印。通过以动画角色关节生成为例的实验结果证明,该方法可以在少量用户交互的基础上,快速在堆砌式3D打印机上打印带有关节的模型,提高关节模型的生成速度。

Currently ,3D printing technology is becoming a rapid development trend as a new technology in the field of rapid prototyping technology .However ,designing the model with joint for 3D printing is complicated and time-consuming through the manual design .In this paper ,a rapid generation method of activated joint based on user interaction is proposed .Firstly ,the model is segmented by the method of user interaction and the segmentation boundary of the model is gotten .Then the entity modeling is carried out through the entity modeling library ACIS and the entity model of activated joint is generated .Finally ,the gridding of the joint model is made and the printing is conducted .T he experimental results of animated character joints generation show that this method can rapidly print the model with joint in the 3D printer based on a small amount of user interaction and increase the generation speed of joint model .
