Abstract: Robocasting is a directed assembly technique, which involves assembly via a layer-by-layer
deposition of colloidal inks. So it offers a powerful alternative for producing complex 3D structures, including space-filling solids and
structures with high aspect ratio walls or spanning (unsupported) elements. Recent advances of this technique were reviewed with an
emphasis on the rheology theory bases and developments of aqueous colloidal gel-based inks. This approach opens up a novel avenue for
engineering complex 3D structures, which may be relevant for a broad range of technological applications.
