Abstract

Official abstract text for this publication.

An apparatus includes a small-diameter-particle powder supplier to supply a small-diameter-particle powder to a surface of an object faulted by binding fabrication powder. The small-diameter-particle powder and the fabrication powder are identical in composition. An average particle diameter of the small-diameter-particle powder is smaller than an average particle diameter of the fabrication powder.

First claim

Opening claim text (preview).

What is claimed is: 1 . An apparatus for fabricating a three-dimensional object, the apparatus comprising: a small-diameter-particle powder supplier to supply small-diameter-particle powder to a surface of an object formed by binding fabrication powder with fabrication liquid; wherein: the small-diameter-particle powder and the fabrication powder are identical in composition, and an average particle diameter of the small-diameter-particle powder is smaller than an average particle diameter of the fabrication powder. 2 . The apparatus as claimed in claim 1 , further comprising a small-diameter-particle powder binder to bind the small-diameter-particle powder on the surface of the object. 3 . The apparatus as claimed in claim 2 , wherein the small-diameter-particle powder binder includes an adhesive applier to apply adhesive, which adheres the small-diameter-particle powder on the surface of the object, before supplying the small-diameter-particle powder on the surface of the object by the small-diameter-particle powder supplier. 4 . The apparatus as claimed in claim 3 , wherein the adhesive includes a binding agent to bind particles of the fabrication powder. 5 . The apparatus as claimed in claim 2 , further comprising: a heater to heat a surface of the object, on which the small-diameter-particle powder is supplied, wherein the heater sinters the small-diameter-particle powder on the surface of the object and heats the surface of the object to bind the small-diameter-particle powder to the surface of the object. 6 . The apparatus as claimed in claim 1 , wherein the small-diameter-particle powder supplier includes a sprayer to spray the small-diameter-particle powder on the surface of the object. 7 . The apparatus as claimed in claim 1 , wherein the small-diameter-particle powder supplier includes a container to store the small-diameter-particle powder, and the container accommodates the object inside the container to supply the small-diameter-particle powder to the surface of the object. 8 . The apparatus as claimed in claim 1 , further comprising: a recovery apparatus to recover the fabrication powder scattered during forming the object, wherein the small-diameter-particle powder supplier utilizes the fabrication powder, recovered by the recovery apparatus as the small-diameter-particle powder. 9 . A method for fabricating a three-dimensional object, the method comprising: binding particles of a fabrication powder to form an object; and supplying a small-diameter-particle powder to a surface of the object, wherein the small-diameter-particle powder and the fabrication powder have an identical composition, and an average particle diameter of the small-diameter-particle powder is smaller than an average particle diameter of the fabrication powder. 10 . The method as claimed in claim 9 , further comprising binding the small-diameter-particle powder to the surface of the object. 11 . The method as claimed in claim 10 , further comprising applying adhesive that adheres the small-diameter-particle powder to the surface of the object before supplying the small-diameter-particle powder on the surface of the object. 12 . The method as claimed in claim 11 , wherein the adhesive includes a binding agent to bind particles of the fabrication powder. 13 . The method as claimed in claim 10 , further comprising: heating the surface of the object, on which the small-diameter-particle powder is supplied, to sinter the small-diameter-particle powder on the surface of the object; and binding the small-diameter-particle powder to the surface of the object by heating the surface of the object. 14 . The method as claimed in claim 9 , wherein the supplying of the small-diameter-particle powder includes spraying the small-diameter-particle powder on the surface of the object. 15 . The method as claimed in claim 9 , wherein the supplying of the small-diameter-particle powder includes: storing the small-diameter-particle powder; and accommodating the object inside a container to supply the small-diameter-particle powder to the surface of the object. 16 . The method as claimed in claim 9 , further comprising: recovering the fabrication powder scattered during forming the object; and utilizing the fabrication powder recovered by the recovering as the small-diameter-particle powder.
