Abstract: This disclosure provides a device for heating to generate a uniform molten pool, including: a source unit for generating an energy beam; a beam expanding/reducing unit positioned in an energy path of the energy beam for adjusting the diameter of the energy beam; a flat-top conical lens set positioned in the energy path and including at least two flat-top axicons, with the beam expanding/reducing unit positioned between the source unit and the flat-top conical lens set; and a focusing lens positioned in the energy path, with the flat-top conical lens set between the beam expanding/reducing unit and the focusing lens, and the energy beam being focused by the focusing lens. This disclosure generates a uniform molten pool to prevent vaporization splash due to overheating of the material during melting.

Abstract: According to embodiments of the disclosure, a flexible device and a fabrication method thereof are provided. The flexible device has a first area and a second area, and the stiffness of a portion of the first area is greater than the stiffness of the second area. The flexible device may include a flexible substrate and a rigid element. The flexible substrate includes a first surface and a second surface opposite to each other. The second surface has a coarse structure. The surface roughness of the second surface is greater in the first area than in the second area. The rigid element is disposed on the first surface of the flexible substrate and located in the first area. The stiffness of the rigid element is greater than the stiffness of the flexible substrate. A projection area of the coarse structure on the flexible substrate overlaps an area of the rigid element.
