Abstract
A method includes generating correction data for a construction material that is used by an additive-manufacturing machine to manufacture an object. This correction data compensates for an interaction of the construction material with first radiation that has been used to illuminate the construction material.
Claims11
An apparatus for using instructions representative of an object to selectively deposit construction material to manufacture said object, said apparatus comprising:
- a printhead having a nozzle that ejects said construction material towards said object and a controller that controls operation of said printhead based at least in part on a depth to a surface of said object,
- wherein said controller is configured to receive first information and second information about said object,
- wherein said first information incorrectly characterizes a depth to a surface of said object, and
- wherein said controller is configured to use said second information in connection with said first information to estimate said depth.
