Abstract
A method for laser transfer and deposition of a rheological fluid wherein laser energy strikes a target substrate comprising a rheological fluid, causing a portion of the rheological fluid to evaporate and propel non-evaporated rheological fluid onto a receiving substrate.
Claims29
A method for laser deposition comprising the steps of:
- providing a receiving substrate;
- providing a target substrate;
- wherein a gap exists between the receiving substrate and the target substrate;
- wherein the target substrate comprises a laser-transparent support coated with a coating on a surface facing the receiving substrate;
- and
- exposing the coating to laser energy through the laser-transparent support at a defined target location comprising a rheological fluid to evaporate a portion of the rheological fluid adjacent to the laser-transparent support at the defined target location;
- wherein the non-evaporated rheological fluid at the defined target location is propelled by the evaporated rheological fluid away from the laser-transparent support and toward the receiving substrate;
- and
- wherein the non-evaporated rheological fluid is deposited at a defined receiving location on the receiving substrate to form a deposit.
