Printed Absorbent: Inner Fluid Design with 3D Printed Object

Using 3D printing technology, it is possible to design objects wherein different regions have different material properties. Recently, researchers started exploring methods to control material properties by using microstructures. For example, metamaterial absorbers have been used with light and acoustics. Research on methods to add functionality by structural design to 3D-printed objects has been widely explored, and we aimed to further these efforts by embedding programmable absorbability into 3D-printed objects.

Printed Absorbent is a novel concept and approach to interactive material utilizing fluidic channels. In this study, we created 3D-printed objects with fluidic mechanisms that can absorb fluids to allow for various new applications. First, we demonstrated that capillary action, based on the theoretical formula, could be produced with 3D-printed objects under various conditions using fluids with different physical properties and different sizes of flow paths. Second, we verified this phenomenon using real and simulated experiments for seven defined flow channels. Finally, we described our proposed interaction methods, the limitations in the design of fluidic structures, and their potential applications. (edited)


Printed Absorbentは、流体チャネルを利用したインタラクティブな素材として、新しいコンセプトとアプローチを採用しています。本研究では、様々な新しいアプリケーションを可能にするために、液体を吸収することができる流体機構を備えた3Dプリントオブジェクトを作成しました。まず、理論式に基づいた毛細管現象が、物性の異なる流体や流路の大きさが異なる流体を用いた様々な条件下で、3Dプリントされた物体で生じることを実証しました。次に、7つに定義した流路構造に基づき、実際の実験とシミュレーションを行い、この現象を検証しました。最後に、我々が提案したインタラクション手法、流体構造設計の限界、およびその応用可能性について述べました。
