Tungsten alloy composite material and 3D printing method thereof

The invention relates to a tungsten alloy composite material and a 3D printing method thereof. The tungsten alloy composite material is prepared from the raw materials including, by mass, 1.5%-2.0% of chromium-plated carbon fibers, 13.0%-18.0% of chromium, 1.5%-2.5% of titanium, 0.4%-0.8% of vanadium, 2.0%-2.5% of molybdenum, 0.1%-0.3% of tin, 0.5%-1.5% of lanthanum, 0.6%-1.2% of hafnium, 0.1%-0.3% of manganese and the balance tungsten and other inevitable impurity elements. According to the tungsten alloy composite material, the types and the use amounts of the raw materials are limited, and the raw materials interact with one another, so that the relative density of the tungsten alloy composite material can be improved, pores and cracks in the tungsten alloy composite material can be reduced or even avoided, and the mechanical properties, especially the impact toughness and hardness, of the tungsten alloy composite material can be remarkably improved. 本发明涉及一种钨合金复合材料及其3D打印方法，按照质量百分比计，该钨合金复合材料由如下原料组成：镀铬碳纤维1.5
