Abstract: A metal powder manufacturing apparatus for a metal 3-dimensional (3D) printer includes a driving unit which generates a rotational force, a metal beam connected to the driving unit to receive the rotational force from the driving unit and having one end disposed in a vacuum chamber, and a shaft support which supports an outer circumference of the metal beam using a magnetic force for relative movement of the metal beam in a lengthwise direction of the metal beam, wherein the shaft support is disposed such that an inner side is spaced apart a predetermined distance from the outer circumference of the metal beam, and can support the metal beam at an adjusted relative distance from the metal beam.
