Zusammenfassung:	To provide a method for application of a binder and selective cure thereof in an addition production process.SOLUTION: The method for layer-by-layer production of a constituting element 76 includes the steps of: accumulating a layer of a particulate material P having a first area on a build platform 14; applying a radiation energy-curable binder B to the layer in a manner that a selected part of the first area is coated uniformly with the binder B; selectively curing a second area of a layer smaller than the selected part of the first area by application of a radiation energy of a specified pattern for defining geometry of a cross section layer of the constituting element 76; and repeating steps of accumulation, application, and cure of a plurality of layers until the constituting element 76 is completed.SELECTED DRAWING: Figure 1 【課題】付加製造プロセスでバインダを適用して選択的に硬化させるための方法の提供。【解決手段】構成要素７６をレイヤーバイレイヤーで生産するための方法は、第１のエリアを有する粒子材料Ｐの層をビルドプラットフォーム１４上に堆積させるステップと、放射エネルギ硬化性のバインダＢを層に、第１のエリアの選択した部分がバインダＢで均一に被覆されるように、適用するステップと、第１のエリアの選択した部分よりも小さい層の第２のエリアを、構成要素７６の断面層のジオメトリを画定する特定のパターンでの放射エネルギの適用を用いて、選択的に硬化させるステップと、複数の層のために、構成要素７６が完了するまで、堆積させる、適用する、および、硬化させるというステップを繰り返すステップと、を含む方法。【選択図】図１
