PROBLEM TO BE SOLVED: To provide a laminate formative apparatus capable of forming a laminate formed article a part of which projects.SOLUTION: The laminate formative apparatus of the embodiment comprises a nozzle device, an optical system, and a control device. The nozzle device includes: a nozzle for supplying powder to an object and irradiating the object with energy rays; and a supplying device for selectively supplying a powdery formative material for forming a layer which forms a formed article, and a powdery support material having a melting point higher than that of the formative material and provided with a bind layer composed of a material having a melting point lower than itself on the surface, for forming a support layer on the upper surface having a layer composed of the formative material formed thereon to the nozzle. The optical system outputs energy rays capable of melting the formative material supplied to the object, and partially melting the support material supplied to the object to the nozzle. The control device drives the nozzle, and can control a supplying amount of the formative material supplied to the nozzle and a supplying amount of the support material to laminate a layer composed of the formative material and a support layer on the object while controlling a power density of the energy rays.SELECTED DRAWING: Figure 1 【課題】一部が張り出す積層造形物の造形可能な積層造形装置を提供する。【解決手段】実施形態の積層造形装置は、ノズル装置、光学系、制御装置を含む。ノズル装置は対象物に粉体を供給し、対象物に対してエネルギー線を照射するノズル、造形物を造形する層を形成する粉体状の造形材料及び造形材料による層をその上面に形成するサポート層を形成する粉体状であって、造形材料よりも高い融点を有し、その表面に自身よりも低い融点の材料によるバインド層を備えるサポート材料を選択的にノズルに供給する供給装置を含む。光学系は対象物に供給された造形材料を溶融可能、対象物に供給されたサポート材料を部分的に溶融させるエネルギー線をノズルに出力する。制御装置はノズルを駆動し、ノズルに供給する造形材料の供給量及びサポート材料の供給量を制御可能で、対象物上に造形材料による層及びサポート層をエネルギー線のパワー密度を制御しつつ積層する。【選択図】図１
