Zusammenfassung:	To provide a 3D printing system, methods and materials for the 3D printing of objects that include a cured hydrogel material, an uncured hydrogel material, and a support material.SOLUTION: The cured hydrogel material may define a scaffold for organs or other biological structures. The 3D printing system selectively deposits the hydrogel material and support material, dries the hydrogel material, and selectively applies a catalyst to the hydrogel material to selectively cure the hydrogel material. Once the 3D printing has been completed, the uncured hydrogel material may be drained and the support material may be melted or dissolved leaving a scaffold of the cured hydrogel material that may be infused with living cells of the desired organ or biological structure.SELECTED DRAWING: Figure 1 【課題】固化ヒドロゲル材料、未硬化ヒドロゲル材料、及び支持材料を含む物体の３Ｄプリンティングのための３Ｄプリンティングシステム、方法、及び材料が提供される。【解決手段】固化ヒドロゲル材料は、器官又は他の生物学的構造のための骨格を定めうる。３Ｄプリンティングシステムは、ヒドロゲル材料及び支持材料を選択的に堆積し、ヒドロゲル材料を乾燥させ、ヒドロゲル材料に触媒を選択的に塗布してヒドロゲル材料を選択的に硬化する。３Ｄプリンティングが完了すると、未硬化ヒドロゲル材料が排出されてもよく、支持材料は硬化ヒドロゲル材料の骨格を残して溶融又は溶解されてもよく、硬化ヒドロゲル材料は所望の器官又は生物学的構造の生体細胞を注入されてもよい。【選択図】図１
