A powder rapid prototyping method includes steps of forming a thin layer 35a of a powder material, irradiating a heating energy beam to a specific region of the thin layer 35a of the powder material to thereby form a preliminary heating layer 35c whose temperature is elevated, and irradiating the heating energy beam to an inside region of the preliminary heating layer 35c whose temperature is elevated to melt and then solidify the thin layer 35a of the powder material to thereby form a solidified layer, wherein the respective steps are repeatedly implemented to fabricate a rapid prototyping model 51, 52. 展开▼
