Classification: CPC C  B | IPC B  C

Claim 7:
8. A method comprising:
directing a first laser toward a target disposed within a chamber to perform in-situ ablation to form a laser plume, the chamber including a nozzle having an aperture;
supplying gas into the chamber, such that the gas interacts with the laser plume, causing the formation of nanoparticles, and directs a flow of the nanoparticles toward and through the aperture of the nozzle, wherein the gas increases pressure in the chamber to a first pressure, wherein the nanoparticles are jetted through the aperture of the nozzle; and
directing a second laser beam toward a substrate disposed at an outlet of the chamber, the second laser beam configured to sinter on the substrate the nanoparticles exiting the nozzle, wherein the substrate is arranged in an environment outside of the chamber and maintained at a second pressure,
wherein the second pressure is atmospheric pressure, and
wherein the first pressure is greater than the second pressure.
