Novel 3D nanoprinting method enables complex metal oxide structures with high fidelity

The field of three-dimensional (3D) nanoprinting has long promised to revolutionize the fabrication of advanced materials and devices. This technology offers the potential to create intricate structures with nanoscale precision, opening up new possibilities in areas such as electronics, optics, energy storage, and sensing. However, progress in 3D nanoprinting of metal oxides has been hindered by several persistent challenges. These include limited material options, significant shape distortion during fabrication, and difficulties in creating heterogeneous structures combining multiple materials.
