Abstract
Method for producing arrays of free standing, three dimensional structures on material surfaces by establishing contact with a template, moving the template and the surface in contact relative to one another, inducing an increase in viscosity such that the structures are self-supported, and removing the template, leaving a negative of the template geometry at the tip of the object.
Claims31
A method of structure formation from a viscous composition comprising:
- changing the relative distance between a template and an upper surface of a viscous composition with first flow characteristics from a distal position to a proximate position closer than the distal position;
- and
- forming free-standing structures of the viscous composition with second flow characteristics, the structures extending a height from a base portion to a tip portion;
- wherein second flow characteristics of the viscous composition comprise rheological properties that are sufficient to retain the structure as free-standing.

A system comprising:
- a template;
- an amount of viscous composition with first flow characteristics;
- a base that holds the viscous composition;
- and
- a relative motion mechanism configured to change the relative distance between a template and an upper surface of the viscous composition;
- wherein the template is selected from the group consisting of a plate with surface features and a roller with surface features.
