Classification: CPC B  G | IPC B  G

Claim 10:
11. A three-dimensional (3D) printer configured to print a 3D object, the 3D printer comprising:
a nozzle;
a camera configured to capture a plurality of real images of a plurality of drops of liquid metal while the drops are positioned at least partially within the nozzle, wherein each drop comprises a meniscus; and
a computing system configured to:
generate a parametric model of motion of the menisci of the drops positioned at least partially within the nozzle based at least partially upon the real images;
generate a plurality of simulated images of the drops positioned at least partially within the nozzle based at least partially upon the parametric model;
generate a labeled dataset that comprises the simulated images and a first set of parameters;
inverse map the real images to a second set of parameters, based at least partially upon the labeled dataset;
reconstruct the menisci of the drops in the real images based at least partially upon the second set of parameters;
extract one or more metrics from the reconstructed menisci of the drops, wherein the metrics comprise a carrier oscillation frequency, a pulse-to-pulse covariance, a waveform decay rate, or a combination thereof; and
adjust one or more parameters of the 3D printer based at least partially upon the one or more metrics to adjust the menisci of the drops positioned at least partially within the nozzle.
