摘　　要：第九届全国大学生结构设计竞赛首次应用3D打印技术进行结点连接件制作,文章以该竞赛为背景,简要介绍了竞赛规则,总结了打印工具的选择、3D绘图技巧、打印参数设置等对构件强度的影响,并分析总结出打印构件的强度及荷重比与打印层厚、打印速度、打印纹路及填充密度的关系。The Ninth National structural design contest for college student has adopted 3D printing technology for making node connecting pieces for the first time. Based on this contest and with brief introduction of the competition regulations,this thesis has summarized the influencing factors of component strengths,such as printing tools,drawing techniques,and printing parameter settings etc. And worked out the relation between printing component intensity and printing layer thickness,printing speed,printing pattern,as well as filling density;and the relation between load ratio and printing layer thickness,printing speed,printing pattern,as well as filling density.

关 键 词：3D打印 强度 3D绘图 结构设计
