a Pictures to show the 3D-printed trefoil knot and boat based on the KCD/TA system. The 3D-printed objects were rinsed with ethanol and postcured under UV flood (50 mW cm−2) for 10 min. Color of the printed objects comes from KCD and KCD_2. b Model of the predesigned microscale hole and the corresponding SEM image based on the KCD/TA system.
