Abstract: An additive manufacturing apparatus includes a main system and a cleaning transportation system separated from the main system. The main system includes an additive manufacturing module. The additive manufacturing module includes an additive manufacturing chamber. The additive manufacturing chamber includes a powder discharging openings and a vibration unit. The powder discharging openings are formed at a lower portion of the additive manufacturing chamber, and the powders in the additive manufacturing chamber are discharged down via gravitation. The vibrational unit is for vibrating the powders so as to accelerate downward powder discharging via vibration of the vibrational unit. The present application solves the conventional problems of excessive consumed energy, large required installation and operational space, inconvenience of powder removing and swirled raised powder haze in the environment.

Abstract: The curved flow channel with built-in lattice structure provided by the present application is configured with the lattice structure disposed at the outer inside wall of the curved section away from a center of curvature of the curved section. Through geometry and distribution design of the lattice structure, flow rate and flow direction of fluid impacting the lattice structure can be altered, which achieves the purpose of flow rate redistribution in the curved flow channel and produces a downstream flow field with uniform distribution.
