Abstract
The present invention relates to architected stamps having beneficial printing properties. In particular, negative Poisson ratio structures and/or porous reservoirs can be employed to control fluid dynamics and to provide metered ink transfer.
Claims22
An architected stamp comprising:
- a porous reservoir comprising a plurality of first pores and a contact surface disposed at a distal portion of the reservoir, wherein the plurality of first pores is in fluidic communication with the contact surface;
- and
- an ink transfer component comprising a plurality of printing elements, wherein each of the plurality of printing elements is in fluidic communication with the contact surface.
An architected stamp comprising:
- a reservoir comprising a contact surface disposed at a distal portion of the reservoir;
- and
- an ink transfer component comprising a plurality of printing elements, wherein each of the plurality of printing elements is in fluidic communication with the contact surface, and wherein each of the plurality of printing elements has a negative Poisson's ratio.
A method of printing comprising:
- providing an architected stamp, comprising
- a porous reservoir comprising a plurality of first pores and a contact surface disposed at a distal portion of the reservoir, wherein the plurality of first pores is in fluidic communication with the contact surface;
- and
- an ink transfer component comprising a plurality of printing elements, wherein each of the plurality of printing elements is in fluidic communication with the contact surface;
- applying an ink to the stamp, thereby delivering the ink to the plurality of first pores of the porous reservoir;
- and
- contacting a distal portion of the ink transfer component to a substrate, thereby transferring the ink from the plurality of pores to the plurality of printing elements and then to the substrate.
