"deposited during 1-step 3D printing: self-assembles before being heat-treated into porous crystalline superconductor... at the atomic scale, atoms line up into a crystalline lattice; block copolymer self-assembly directs mesostructured lattice formation; 3D printing macroscopic lattices, including coils/ helices... printed niobium-nitride material superconductor with 40 to 50 Tesla magnetic field (future: titanium nitride)... compound superconductors in quantum devices, superconducting magnets such as those used in MRI"
