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.
Claims19
An architected stamp having a proximal end and a distal end, comprising:
- a porous reservoir comprising a plurality of first pores and a contact surface disposed at a distal portion of the porous 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 includes one or more compressible structures in fluidic communication with the contact surface at a proximal portion of the ink transfer component and which can be mechanically deformed to deliver ink to a substrate at a distal portion of the ink transfer component and wherein the proximal portion of the ink transfer component is separated from distal portion of the porous reservoir by the contact surface.
An architected stamp having a proximal end and a distal end, 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 at a proximal portion of the ink transfer component and wherein the proximal portion of the ink transfer component is separated from the distal portion of the reservoir by the contact surface.
A method of printing comprising:
- providing an architected stamp having a proximal end and a distal end,
- comprising
- a porous reservoir comprising a plurality of first pores and a contact surface disposed at a distal portion of the porous 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 includes one or more compressible structures in fluidic communication with the contact surface at a proximal portion of the ink transfer component and wherein the proximal portion of the ink transfer component is separated from the distal portion of the porous reservoir by 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 mechanically deforming the plurality of printing elements and transferring the ink from the plurality of pores to the plurality of printing elements and then to the substrate.
