Fig. 1: Conceptual illustration of patterning liquid with the 3D printed micromesh.

A Schematic explanation of the liquid patterning of post-based 2D microchannels to 3D micromesh guided patterning using Hy-MAP. The liquid was patterned in 3D mesh channel structure by surface tension. B Photograph and scanning electron microscope images of a cubic trefoil and Möbius’ twisted structure, which were difficult to fabricate with conventional manufacturing methods. The size of the gap is 800 μm and the thickness of the line structure is 200 μm.
