To provide a new binder solution enabling the monitoring of an additional production process and a method for producing a green body component with the binder solution.SOLUTION: A method for producing a green body component comprises a step in which the layer of powder 202 is deposited on a work plane 204 and a step in which a binder solution 206 comprising a thermoplastic binder 216, a fluorescent material 220 and a binder medium is selectively applied to the layer of the powder in a pattern representative of a structure of the layer of a green body component. The thermoplastic binder comprises one or more polymer strands dissolved in a solvent medium and having the average molecular weight of 7,000 or more to 100,000 g/mol or less. Also provided are a binder solution comprising a fluorescent material and a green body component adhered together with the same.SELECTED DRAWING: Figure 2 【課題】付加製造プロセスのモニタリングを可能にする新たなバインダ溶液、および該バインダ溶液を使用したグリーン体部品の製造方法を提供する。【解決手段】グリーン体部品の製造方法は、作業面２０４上に粉末２０２の層を積層させることと、前記粉末の層にグリーン体部品の層の構造を表すパターン状に熱可塑性バインダ２１６、蛍光材料２２０、及びバインダ媒体を含むバインダ溶液２０６を選択的に付与することであって、前記パターンはグリーン体部品の層の構造を表す、バインダ溶液を選択的に付与することと、を含む。前記熱可塑性バインダは、溶媒媒体に溶解した７，０００ｇ／ｍｏｌ以上１００，０００ｇ／ｍｏｌ以下の平均分子量を有する１又は複数のポリマーストランドを含む。蛍光材料を含むバインダ溶液、及びこれを用いて一緒に接着したグリーン体部品も提供される。【選択図】図２
