What is it about?

A novel liquid-in-liquid 3D printing technique is developed which enables the fabrication of robust constructs with internal phase nanostructures and with tunable mechanical behavior. Such approach is enabled through the use of surfactant self-assembly at water-oil interface.

Why is it important?

The printed constructs in this work are structured at nanoscale which can impart functionalities to them while their mechanical behavior can be tuned based on the composition of the printing phase. In this liquid-in-liquid technique the printing phase is low viscous aqueous solution and the support bath is interestingly an oil phase. For this approach, the surfactant self-assembly is the enabling factor rather than limiting rheological properties of the bath which is the case for other liquid-in-liquid 3D printing techniques.
