1. A method for additive manufacturing comprising:

  • fabricating an object based on a three-dimensional model with a printer, wherein the printer is a three-dimensional metallic printer configured to additively manufacture the object with a number of droplets of liquefied metal as a build material using a metallic liquid expeller;

    acquiring surface data from the object with one or more sensors during fabrication, the surface data characterizing a location on a layer of a build material of the object deposited by the printer;

    estimating a target surface shape for the build material at the location based on the three-dimensional model;

    comparing the surface data to the target surface shape at the location; and

    adjusting a fabrication process when a discrepancy is identified between the surface data and the target surface shape.
