1. A method for forming a physical object from a virtual model comprising:
within a working volume:
providing a build plate comprising an interface layer;
fabricating an object precursor, comprising a geometry corresponding to the virtual model, on the interface layer, wherein fabricating the object precursor comprises iteratively:
depositing a build material layer over the interface layer; and
machining the build material layer, wherein the interface layer retains the build material layer during build material machining; and
sintering the object precursor to form the physical object at a temperature between 400-1384° C., wherein the interface layer releases the physical object from the build plate during sintering.
