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: An insert coaxial thermal radiation image evaluating system includes a cage support, first lens, first cage movable frame, second cage movable frame, cage holder and light detector. The first cage movable frame is movably disposed at the cage support and connected to the first lens. The second cage movable frame is movably disposed at the cage support and connected to the light detector. The cage holder is connected to the cage support to fix the cage support to an optical substrate. The first cage movable frame is movably disposed in the cage holder. The first lens and a second lens of a metal additive manufacturing system together form a structure of conjugate foci, such that a thermal radiation generated from a high-power infrared laser irradiation zone forms according to a fixed ratio an image captured by the light detector.

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.
