Abstract: A powder recycling system includes a supply tank, a continuous loss-in-weight module, a pneumatic module, a transfer channel, a recycle module, and a refilling tank. The supply tank accommodates recycling powder. The continuous loss-in-weight module includes a storage tank receiving the recycling powder from the supply tank and a rotary output pipe connected to the storage tank to output the recycling powder. The continuous loss-in-weight module controls the mass flow rate of the output of the recycling powder according to the weight change of the storage tank. The pneumatic module enables the recycling powder to float and move in the transfer channel. The recycle module is connected to the transfer channel to receive the recycling powder, sieves the recycling powder, provides virgin powder, and mixes the virgin powder with the recycling powder. The refilling tank is connected to the recycle module to receive the recycling powder and the virgin powder.

Abstract: The present application provides not only a heating device for additive manufacturing but also a heating module and a manufacturing apparatus utilizing the heating device. The heating device utilizes a rotational reflective cover to modulate a heating direction of a heating source, which expands an area correspondingly irradiated by the heating source and enhances uniformity of heating. Besides, the heating modules can be coupled and controlled by a controlling subsystem so as to respectively irradiate different areas with ranges at least partially intersecting each other, which also improves heating uniformity for heating a large area.

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.
