空间薄壁结构成型3D打印工艺实验研究——以红船模型打印为例

Experimental study on 3D printing process of thin wall space structure: taking red ship model printing as an example

空间薄壁结构具有厚度远小于自身其他尺寸,承受曲面内的轴向力且弯矩小的特点,在3D打印中存在成型难控制的问题。文章以小型红船模型打印为例,采用逆向工程技术,采集红船模型数据并建模,采用3D打印技术,设置若干工况,研究了不同材料、打印速度、冷却方法等对模型成型的影响。

Space thin-walled structure is much thinner than its other dimensions, and it bears axial force in curved surface with small bending moment,Therefore, it is difficult to control the molding in 3D printing. Taking the printing of small red ship model as an example, using reverse engineering technology to collect the data of the red ship model and model it. The 3D printing technology is used to set up several working conditions, and the effects of different materials, printing speed, cooling methods, etc. on the model forming are studied.
