Abstract
The present invention provides a method, which infiltrates super-heated material between preheated powder particles and therefore minimizes heat deformation and increases measurement accuracy. A rapid prototyping apparatus in accordance with the present invention comprises powder material spreading means,, dispensing infiltration material means,, laser beam scanning means,, and control means. The powder material spreading means spread out powders,on the surface of platform,uniformly while moving along the X axis. The powders are the main material of desired products. The dispensing infiltration material means dispense infiltration materials,while moving along three axes and the super-heated infiltration materials,by laser beam,are infiltrated between the powders selectively. The laser beam scanning means preheat the powders by laser beam,within the melting point of the powders and super-heat the infiltration material by laser beam,. The control means control the powder material spreading means, the dispensing infiltration material means, and the laser beam scanning means on the basis of modeling data of the desired products.
