The invention provides a preparation method of a fine-sand-shaped raw material, and aims to overcome the defects of unstable preparation and mixing as well as poor uniformity in the fine-sand raw material for additive manufacturing equipment. According to the preparation method of the fine-sand-shaped raw material, a butterfly valve type switch component is arranged on a hardware component, and hardware actions are controlled through software in order to realize accurate control of the adding amount. In the preparation method of the fine-sand-shaped raw material, a reasonable stirring structure is provided, and the stirring time is controlled, so that the mixing uniformity is realized, thereby ensuring the accuracy of raw material preparation and the mixing uniformity, and guaranteeing theproduction of qualified products. 本发明克服了增材制造设备细砂状原材料的配置与混料不稳定、均匀性差的不足，提供了种细砂状原材料的配料方法。所述细砂状原材料的配料方法通过在硬件部件上设置蝶阀类开关部件、并通过软件控制硬件动作，从而实现加入量的准确控制；所细砂状原材料的配料述方法通过设置合理的搅拌结构和对搅拌时间的控制，实现了混料的均匀性，从而保证了原材料配置的准确性和混料的均匀性，进而为生产合格的产品提供保障。
