Abstract: A hollow structure is formed from ceramic. The hollow structure includes a main body part and a reinforcing part. The main body part has a spherical outer peripheral surface, and inside the main body part, a hollow is formed. The reinforcing part is formed integrally with the main body part on an inner peripheral surface of the main body part and reinforces the main body part.

Abstract: A stage mechanism for use in an additive manufacturing device for forming a three-dimensional shaped object by stacking layers, which are formed by a layer forming unit, on a layer-by-layer basis, the stage mechanism including a porous plate configured to adhere a flexible sheet by vacuum suction and a base supporting the porous plate and having a space defined inside of the base, and an inlet port configured to connect the space and a decompression device, wherein the base moves up and down relative to the layer forming unit of the additive manufacturing device so that the shaped object is formed on the flexible sheet adhered, by vacuum suction, to the porous plate, and a pore diameter of the porous plate is less than the thickness of the flexible sheet.
