A blast nozzle for a depowdering apparatus includes an abrasive material inlet fluidly connected to an abrasive material outlet and a fluid inlet fluidly connected to a fluid outlet, where the fluid outlet at least partially surrounds the abrasive material outlet. The fluid outlet is angled with respect to the abrasive material outlet and configured to emit a fluid stream directed to a focal point, the focal point being laterally spaced apart from the blast nozzle in a fluid flow direction.
