Surface tension-assisted additive manufacturing. a Schematic of the material fabrication process. b The 3D-printed reticulated scaffold is dipped into a liquid precursor solution. c Surface tension forces suspend a liquid film on the surface of the scaffold as the scaffold is withdrawn from the solution. d The suspended liquid film is crosslinked into a solid film by, for example, photopolymerization. e A stable solid coating is formed on the 3D-printed reticulated material
