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.
Claims11
A heating device for additive manufacturing, the heating device comprising:
- a heating source;
- a reflective cover covering the heating source and formed in a curved shape, an inner surface of the reflective cover facing towards the heating source, the inner surface being made of thermal radiation reflective material;
- a cover rotating unit for rotating the reflective cover;
- a rotation controlling unit for controlling rotation of the cover rotating unit;
- and
- a heating source holder for holding the heating source, the reflective cover, the cover rotating unit and the rotation controlling unit;
- wherein the rotation controlling unit controls the cover rotating unit to rotate the reflective cover so as to modulate a heating direction of the heating device to perform a scanning heating process for irradiating different areas.
