Zusammenfassung:To provide a powder module device capable of attaining secure sealing between a powder module and an attending lid.SOLUTION: A powder module device 1 for an apparatus of additionally producing a three-dimensional object by continuously selectively irradiating and solidifying the layers of a powdery molding material 2 solidified with an energy beam comprises: a powder module 3 provided with a molding material receiving volume 9 composed so as to receive the molding material 2, a plurality of bottom wall elements 7 dividing the opening 10 thereof and at least one side wall element 8; a lid 4 provided with a lid-base body 11 composed so as to close the opening 10 in the closed state of the module device 1; and a sealing device 5 of sealing a space between the powder module and 3 and the lid 4 in a closed state, particularly, liquid-resistantly. The sealing device 5 includes an expandable sealing element, and the sealing element has an expandable volume.SELECTED DRAWING: Figure 1 【課題】粉末モジュールと付随するリッド(ふた)との間の確実な封止を可能にする粉末モジュール・デバイスの提供。【解決手段】エネルギービームで固化される粉末状の造形材料2の層を連続して層ごとに選択的に照射及び固化することで3次元の物体を付加製造する装置向けの粉末モジュール・デバイス1は、造形材料2を受け取るように構成される造形材料受取り体積9、その開口10を区切る複数の底壁要素7及び少なくとも1つの側壁要素8を備える粉末モジュール3と、モジュール・デバイス1の閉鎖状態で開口10を閉鎖するように構成されたリッド・ベース体11を備えるリッド4と、閉鎖状態で粉末モジュール3とリッド4との間を特に耐液性に封止する封止デバイス5とを備え、この封止デバイス5は膨張可能な封止要素を備え、封止要素は膨張可能な体積を備える。【選択図】図1
