Additive nanomanufacturing system and method

A device comprising:

• a chamber defined by a housing including at least one aperture;
• one or more targets disposed within the chamber;
• at least one first laser configured to generate a first beam directed through the housing and into the chamber toward the one or more targets to perform in-situ ablation to form a plume;
• a gas flow system configured to supply at least one gas into the chamber and flow through the chamber such that the at least one gas interacts with the plume and causes the formation of nanoparticles that flow out of the chamber through at least one aperture, wherein the gas increases pressure in the chamber to a first pressure greater than atmospheric pressure;
• and
• at least one second laser configured to generate a second beam toward a substrate disposed in an environment outside the housing maintained at atmospheric pressure, the at least one second laser beam configured to sinter the nanoparticles passing through the aperture on the substrate.

A method comprising:

• directing at least one first laser beam toward a target disposed within a chamber to perform in-situ ablation to form a laser plume;
• supplying at least one gas into the chamber such that the at least one gas interacts with the laser plume, causing the formation of nanoparticles, and directs a flow of the nanoparticles toward and through an opening of the chamber, wherein the at least one gas increases pressure in the chamber to a first pressure;
• and
• directing at least one second laser beam toward a substrate disposed adjacent to the opening of the chamber, the at least one second laser beam being configured to sinter on the substrate the nanoparticles exiting the opening in the chamber,
• wherein the substrate is arranged in an environment outside of the chamber that is maintained at atmospheric pressure, and
• wherein the first pressure is greater than atmospheric pressure.
