Abstract
Recently, rapid prototype technique becomes to be used many fields, and the stereo lithograph method or other methods are interested in. However, these methods can produce only plastic parts, it is difficult to produce metallic or ceramic parts. And, it limits the application of these methods. Therefore, new rapid prototype methods that can form metal or ceramic powder are desired. The laser sintering method is one of the methods that can form the metallic parts. In this method, the metal powder is sintered by laser beam and the powder is combining each other by melting the powder surface. Though, the parts obtained by this method are porous. Also, it is difficult to apply this method to the sintering of ceramic powder. To overcome these difficulties and actualize the rapid prototype of metallic and ceramic parts, a new method using FDM (Fused Deposition Method) is investigated.
