Abstract
A method provides a device having a feeder vessel, a building vessel with a bottom and a fabrication plate that is movable in vertical translation, a transfer system suitable for depositing powder from the feeder vessel to the building vessel as a powder layer of constant thickness, and a high energy beam optical system suitable for scanning the surface of the deposited powder layer. A powder is placed in the feeder vessel. A first series of powder layers is deposited on the fabrication plate. The particles of powder are melted or sintered to form a plurality of columns of material that are separated from one another by particles of powder. A second series of layers of powder is deposited on the first series of layers of powder particles to form a single-piece element. A thermal insulation platform is formed between the fabrication plate and said single-piece element.
