Concept of embedded ink writing (EIW). A polysiloxane ink is printed by a direct ink writing (DIW) 3D printer in Newtonian fluids as embedding media. The surrounding liquid media allow the inks to maintain larger contact angles (> 100o) on the substrates. Inks for EIW can be functionalized by suspending functional microparticles (e.g., embedding thermochromic leuco dye microparticles).
