US 2015/0174822 A1 · APPARATUS AND METHOD FOR ADJUSTING AND CONTROLLING THE STACKING-UP LAYER MANUFACTURING

Abstract

An apparatus of adjusting and controlling the stacking-up layer manufacturing comprises a target, a powder providing unit, an energy generating unit, and a magnetism unit. The powder providing unit is coupled on a top of the target. The energy generating unit is also coupled on the top of the target. The powder providing unit provides a powder to a surface of the target. The energy generating unit provides the energy beam to selectively heat the powder on the surface of the target to form a melted or sintered powder layer. The magnetism unit provides a magnetic field to control the solidification of the melted or sintered powder layer.

A control method for an apparatus for adjusting and controlling the stacking-up layer manufacturing, the apparatus comprising a target, a powder providing unit for providing a powder onto the target, an energy generating unit for providing an energy beam and a magnetism unit for generating a magnetic field, the control method comprising the steps of:

(a) providing the powder onto a surface of the target;
(b) directing the energy beam onto the powder on the surface of the target to form a melted or sintered powder layer;
(c) applying the magnetic field to the melted or sintered powder layer so as to control a solidification process of the melted or sintered powder layer and further to form a solidified layer, wherein a material microstructure of the solidified layer is varied via controlling the solidification process;
and
(d) performing repeatedly the steps (a), (b), and (c) till a 3D product is formed by a sequence stacking with the solidified layers.
