| 專利摘要 | 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. |
