结构建模竞赛3D打印节点的设计与优化

Design and optimization of 3D printing node in structure design contest

3D打印在土木工程行业中具有良好的应用前景,然而在目前的教学中鲜有涉及。第九届全国大学生结构建模大赛中首次引入了3D打印节点装配模型的制作。以湖南科技大学参赛作品为例,从3D打印节点的设计、优化和安装等角度,阐述了3D打印在大学生结构建模中的应用。构件由3D打印节点采用"卡""插""楔""套"4种方式进行组装,效果良好。大赛对土木工程专业本科生普及3D打印技术、拓展专业视野具有较好促进作用。

3D printing has a good application prospect in the civil engineering industry, while this frontier knowledge is not covered in the current teaching. 3D print node assembly model was first introduced in the ninth national structure contest for college students. Taking the competition works of Hunan University of Science and Technology as an example, the application of 3D print in structure design for college students was expounded from the point of design, optimization and installation. The structure was well assembled with 3D print node by sticking,inserting, wedging and interlinking. The competition would promote the popularization of 3D printing technology and expand professional vision for college students in civil engineering.
