Robocasting is a 3D printing technology based on the continuous extrusion of a paste (or ink) to build parts layer by layer.

These pastes should flow through a narrow printing nozzle (usually 0.1-1 mm in diameter) and then sustain the weight of the printed part.

Dr Iuliia Elizarova, Imperial College London, Post Doctoral Research Associate, gives an overview of robocasting in this short video.
