fabricated a tungsten collimator component for computed tomography equipment only a density of 89.2% was achieved. tried to additively manufacture pure tungsten parts and found that the densification is difficult due to the balling phenomenon. Therefore, additive manufacturing (AM) of tungsten, which can produce metal parts with complex inner and outer structures, has attracted the attention of many researchers. Due to the high brittleness, tungsten parts are difficult to be mechanically processed and are conventionally fabricated via powder metallurgy method, which encounters some difficulties in the production of a complex structure. In the international thermonuclear experimental reactor (ITER), tungsten is considered as the most promising candidate for plasma-facing materials owing to its high resistance to irradiation and low erosion yield. ![]() Possessing high melting point (3693 K), high thermal conductivity, and strong mechanical properties, tungsten has been widely used in military and electrical industries.
