Classification: CPC G  B  Y | IPC B  G

Claim 4:
5. A three-dimensional (3D) metal object manufacturing system comprising:
a printhead configured to eject drops of melted metal toward a platform;
an optical sensor configured to generate image data of a metal object being formed by the 3D metal object manufacturing system on the platform prior to completion of the metal object; and
a controller operatively connected to the optical sensor and the printhead, the controller being configured to:
compare the generated image data of the metal object to original 3D object design data to identify a difference;
identify a displacement error as the identified difference when the identified difference is outside a predetermined difference range;
modify machine-ready instructions by changing drop spacing parameters identified in the machine-ready instructions for forming metal object layers not yet formed to compensate for the identified displacement error, the drop spacing parameters being changed by using a linear function; and
operate the 3D metal object manufacturing system using the modified machine-ready instructions.
