The invention discloses a CubeSat framework based on 3D printing, which comprises a side frame and a connecting screw rod, and further comprises fixing tables and a solar cell panel, four fixing tables are connected in the side frame, the surfaces of the fixing tables are connected with the connecting screw rod, the outer surface of the connecting screw rod is sleeved with a circuit board. A large circular hole and a small circular hole are formed in the outer surface of the side frame, and a power switch is arranged on the inner side wall of the side frame. According to the CubeSat framework based on 3D printing, the selective laser melting metal 3D printing technology is adopted, the structural strength of the CubeSat framework reaches up to 500 MPa, the weight of the CubeSat framework is half of that of a traditional method, the design and manufacturing period is shortened, and on the basis that an original CubeSat framework loads different functional loads, the strict requirement of a spacecraft for the load quality can be better met.
本发明公开了一种基于3D打印的立方星框架,包括侧面框架和连接螺杆,还包括固定台和太阳能电池板,所述侧面框架的内部连接有4个固定台,所述固定台的表面与连接螺杆连接,所述连接螺杆的外表面套接有电路板,所述侧面框架的外表面分别设开设有大圆形孔和小圆形孔,所述侧面框架的内侧壁设置有电源开关。该基于3D打印的立方星框架,采用一种选择性激光熔化金属3D打印技术,其结构强度高达500MPa,重量为传统方法的一半,设计制造周期缩短,在实现原有立方星框架装载不同功能载荷的基础上,更能适应航天器对载荷质量的严格要求。
