发明名称 Powder for quick manufacturing of three-dimensional bodies, e.g. building prototypes from a data model, and method of manufacturing the powder
摘要 <p>A body is assembled through composite layers of the powder. The layers are fused together by the application of heat through a model mask. This treatment means the powder undergoes as little volume change as possible, thus making the bodies shape closer to that specified in the design. The powder contains two materials, one that melts to provide composite fusion under heating, and one that changes it's volume very little through an entire heat cycle. An independent claim is also included for a method of manufacturing the powder.</p>
