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.
Claims21
A print structure, comprising:
- a surface;
- a plurality of actuators embedded within the surface;
- and
- a pattern layer that selectively actuates one or more of the plurality of actuators to selectively form one or more wells in the surface to create a defined pattern on the surface in which a material is applied and subsequently transferred to another surface.
1 more element
A print structure for transferring materials, comprising:
- a first layer, including;
- a foil sheet,
- one or more apertures embedded 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 on a surface of the foil sheet;
- 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.
4 more elements
A method for printing viscous materials, comprising:
- deforming portions of a print surface with an electrostatic field in order to create one or more wells within the print surface;
- applying a viscous material to the surface;
- using pressure to push the viscous material into the wells;
- and
- transferring the material to another surface.
2 more elements
A print structure:
- including
- a layer;
- and
- a surface of the layer in which a static indentation is formed in the surface in response to one or more stimuli and the static indentation is removed from the surface in response to a second one or more stimuli.
