PRODUCTION OF SHAPED PART WITH THREE DIMENSIONAL FORM

摘要

PROBLEM TO BE SOLVED: To easily obtain a dense, high precision shaped part in a method of producing a shaped part with three dimensional form by laminating laser beam hardened layers of powder. SOLUTION: An inorganic or organic powder material is irradiated with laser beam to form a hardened layer, and one hardened layer is laid on another to produce the desired parts of three dimensional form. This method includes steps of: (a) feeding a powder material 31 to the shaping region where a hardened layer is formed by laser beam irradiation; (b) applying vibration to the powder material 31 fed to the shaping region; (c) applying pressure to the powder material 31 fed to the shaping region; and (d) forming a hardened layer by irradiating the powder material 31 with laser beam after the steps (b) and (c).
