Extended Data Fig. 7: 3D printing of BIN gels.
a, Models for 3D printing of BIN gels. b, Structure and a demonstration of mechanical properties of the printed gel. The printed gel, 10 mm in outer diameter, 7 mm in inner diameter, and 2 mm in thickness, was post-cured by exposing to 395-nm light for 30 seconds (0.5 W/cm2 power), which conferred a material that could then sustain a load of 0.5 kg. c, 3D printed conical and hollowed-out structures composed of the BIN gel material. The Rw was 0.22. These structures demonstrated the high precision and the unlimited types of patterns that can be achieved via 3D printing of BIN gels.
