摘　　要：3D模型资源一般是静止封闭的网格,无法为3D打印提供可活动的输入结构。针对非专业用户创建可打印的活动模型,进行了活动关节共性参数化设计与参数求解研究,通过实验得到了影响可活动性的共性阈值参数极限。在此基础上,提出一种易于使用的为静止模型添加活动关节的方法,生成了若干可活动四肢的玩偶模型与功能化的生活用品模型。最终3D打印结果说明该方法所设计的关节丰富有效,产生活动模型灵活快速,用户认可度高。3D model can't be afforded to3D printer an activate structure,because it is generally closed mesh which is static.Aimed to creating a printable activate model for non-professional users,this paper studies common parameters design of the active joints and the solving of parameters,while gets the limit of the threshold parameters that would influence the performance of activity.On this basis,an easy to use method that can add active joint to static model is proposed,which can generator some doll's models with moved limbs and functional models for daily use.The results of3D printing demonstrate the joints originated from the design of this paper are enrich and valid.The method creating active model is quickly and flexible,and has been accepted by most users.
