Abstract
A print structure includes a pattern layer that selectively actuates one or more of a plurality of actuators to selectively form one or more wells in a print surface to create a defined pattern on the print surface. A material is applied to the one or more wells and subsequently transferred to another surface in order to transfer the pattern.
Claims6
A print structure for transferring materials, comprising:
- a first layer, including;
- a foil sheet,
- one or more apertures within the foil sheet, and
- one or more pistons that move within the one or more apertures to form one or more wells for holding a material within said one or more wells, wherein the one or more pistons are in electrical communication with the foil sheet such that there is a flow of electrons between the foil sheet and the one or more pistons;
- an elastomer in which the one or more pistons are pulled into when forming the one or more wells;
- and
- a photoconductor that switches an electric field across the elastomer.
