Abstract
A method of calibrating an apparatus for generating a three-dimensional object is described in which a calibration substrate is generated by depositing build material and applying energy to the build material to form a fused surface; a calibration pattern is generated on the calibration substrate by depositing an agent on the calibration surface according to a predetermined pattern; and an attribute of the calibration pattern is measured.
Claims15
A method of calibrating an apparatus for generating a three-dimensional object, the method comprising:
- generating a calibration substrate by depositing build material and applying energy to the build material to form a fused surface;
- generating a calibration pattern on the calibration substrate by depositing an agent on the calibration substrate according to a predetermined pattern;
- and
- measuring an attribute of the calibration pattern.
An apparatus for generating a three-dimensional object, the apparatus comprising:
- a build material deposition system to deposit build material;
- an energy application system to apply energy to deposited build material;
- an agent deposition system to deposit an agent;
- a measurement system;
- and
- a processing unit to:
- control the build material deposition system and the energy application system to generate a calibration substrate by depositing first build material and applying energy to the first build material to form a fused surface;
- control the agent deposition system to generate a calibration pattern on the calibration substrate by depositing an agent on the calibration substrate according to a predetermined pattern;
- and
- control the measurement system to measure an attribute of the calibration pattern.
A non-transitory machine-readable storage medium encoded with instructions executable by a processor, the machine-readable storage medium comprising:
- instructions to generate a calibration substrate by depositing build material and applying energy to the build material to form a fused surface;
- instructions to generate a calibration pattern on the calibration substrate by depositing an agent on the calibration substrate according to a predetermined pattern;
- and
- instructions to measure an attribute of the calibration pattern.
