The invention discloses an additive manufacturing method for a multi-material controllable radiation-shielding space suit assembly. The additive manufacturing method comprises the following steps: manufacturing a special material for printing according to radiation requirements; designing a shielding assembly structure, with different material component proportions and different densities, for each part according to difference of body structures and shielded parts of astronauts; performing slicing treatment on the shielding assembly structure of each part in a computer to obtain discrete data,and planning a printing path to print radiation shielding part of each part of a space suit; and spraying out continuous fibers of micro-nano scales through an electrostatic spinning process, adhering the continuous fibers among the radiation-shielding parts, thereby forming a flexible radiation-shielding fiber layer, wherein the radiation-shielding parts of each part are connected to the flexible integrated radiation-shielding space suit assembly through radiation-shielding fiber layer. The additive manufacturing method overcomes the defect that radiation-shielding performance of the conventional space suit cannot be regulated, and also solves the problem that softness and comfort is poor as a result of sewing of a multi-layer seam shielding material.
一种多材料可控辐射屏蔽宇航服组件增材制造方法，先根据辐射要求制备成打印用的专用材料；然后根据宇航员身体构造、屏蔽部位的不同，设计具有不同材料组分比例、密度的各部位屏蔽组件结构；在计算机中对各部位屏蔽组件结构进行切片处理得到离散化数据，进行打印路径规划，打印出宇航服各部位的辐射屏蔽部件；最后通过静电纺丝工艺喷射出微纳米尺度的连续纤维，使其附着在辐射屏蔽部件的之间，形成柔性的辐射屏蔽纤维层，辐射屏蔽纤维层将各个部位的辐射屏蔽部件连接起来形成柔性一体化的辐射屏蔽宇航服组件；本发明克服了传统宇航服辐射屏蔽性能不可调节的缺点，也解决了由多层缝屏蔽材料缝制引起的柔性和舒适性差的问题。
