Rapid Prototyping Model, Powder Rapid Prototyping Device and Powder Rapid Prototyping Process

摘要

A powder rapid prototyping method comprises the steps of forming a thin film 35a of a powder material, irradiating a heating energy beam onto a certain portion of the thin film 35a of the powder material to thereby form a preliminary heating film 35c whose temperature is elevated, and irradiating the heating energy beam to an inner portion of the preliminary heating layer 35c whose temperature is raised to melt and then solidify the thin layer 35a of the powder material to thereby form a solidified layer, the respective steps being repeatedly performed to produce a rapid prototype Model 51, 52 produce.
