Controllability: Interface Manipulation for Printing Three‐Dimensional Microstructures Under Magnetic Guiding (Small 16/2015)

Three-dimensional microstructures of hat, cone, pillar, and spindle shapes are prepared by Y. Song and co-workers based on interface manipulation by inkjet printing. On page 1900, the 3D morphologies are precisely controlled by the 2D interfacial properties of the substrate. Accurately positioned and oriented patterning of 3D arrays are facilely achieved, demonstrating the high controllability of this strategy to fabricate uniform 3D microstructures on a large scale. This advance will present significant insight and promising applications in controllable 3D manufacturing.
