A method of additively manufacturing a part is provided. The method includes flowing masticated particles through a deposition nozzle of a directed energy deposition additive manufacturing apparatus.Each particle of the masticated particles includes a surface formed by at least angular facets. The method also includes melting the masticated particles exiting the deposition nozzle with a directedenergy source of the directed energy deposition additive manufacturing apparatus so as to form the part. 提供了一种增材制造零件的方法。该方法包括使粉碎颗粒流动通过定向能量沉积增材制造设备的沉积喷嘴。粉碎颗粒中的每个颗粒都包括由至少有角的刻面形成的表面。该方法还包括用定向能量沉积增材制造设备的定向能量源熔化从沉积喷嘴中离开的粉碎颗粒以便形成零件。
