Quantum dot matrix printer creates 3D structures

Quantum dots have been turned into 3D printer ink by researchers in China. The technique could be used to make advanced light-emitting devices or photodetectors.

3D printing offers new ways to make all sorts of different products, but the technique generally relies on traditional polymers. Many researchers hope that incorporating inorganic materials into 3D printer ink could make it possible to print more functional products with advanced electronic and optical properties. While some methods do exist where hybrids of organic and inorganic materials can be used in 3D printing, the organic components can reduce electronic conductivity and thermal stability.
