Stereolithography powder material, hardening liquid, and stereolithography kit, as well as the three-dimensional object manufacturing method and apparatus

A complex three-dimensional object shape may easily and efficiently by using a powder material such as metal, a manufacturing method of three-dimensional object shapeless be produced with high dimensional accuracy without causing the front of such sintering, etc. the provision of. A using powder material for stereolithography containing an organic material substrate coated with a powder material layer forming step of forming a layer of powder material, the powder material layer formed by said powder material layer forming step , the organic material and by applying a curable liquid containing a crosslinking agent for crosslinking, a three-dimensional object to produce a three-dimensional object and the powder material layer hardening step of hardening the predetermined area, with the least repetition of powder material layer it is a manufacturing method. .FIELD 1
