Abstract
A method for additively manufacturing three-dimensional objects includes generating a laser beam with one or more laser beam sources and modulating the laser beam via one or more modulation devices to generate a modulated beam based on a set of one or more defined parameters where the modulated beam is directed onto a build plane. One or more sensor devices detect first data corresponding to one or more measured parameters of the modulated beam and second data corresponding to reflected radiation from the build plane. The set of the one or more defined parameters is modified based on the first data and the second data.
Claims20
A method for additively manufacturing three-dimensional objects, the method comprising:
- generating a laser beam with one or more laser beam sources;
- modulating the laser beam via one or more modulation devices to generate a modulated beam based on a set of one or more defined parameters;
- directing the modulated beam onto a build plane;
- detecting, via one or more sensor devices:
- first data corresponding to one or more measured parameters of the modulated beam;
- and
- second data corresponding to reflected radiation from the build plane;
- and
- modifying the set of the one or more defined parameters based on the first data and the second data.
An apparatus for additively manufacturing three-dimensional objects, the apparatus comprising:
- one or more laser beam sources configured to generate a laser beam;
- one or more modulation devices disposed downstream of the one or more laser beam sources and configured to receive the laser beam and generate a modulated beam based on a set of one or more defined parameters;
- one or more optical devices disposed downstream of the one or more modulation devices and configured to direct the modulated beam onto a build plane;
- one or more sensor devices configured to detect:
- first data corresponding to one or more measured parameters of the modulated beam;
- and
- second data corresponding to reflected radiation from the build plane;
- and
- a controller configured to manipulate the set of the one or more defined parameters based on the first data and the second data.
A non-transitory computer-readable medium comprising computer-executable instructions, which, when executed by a processor associated with an additive manufacturing machine, cause the processor to perform a method comprising:
- generating a laser beam with one or more laser beam sources;
- modulating the laser beam via one or more modulation devices to generate a modulated beam based on a set of one or more defined parameters;
- directing the modulated beam onto a build plane;
- detecting, via one or more sensor devices:
- first data corresponding one or more measured parameters of the modulated beam;
- and
- second data corresponding to reflected radiation from the build plane;
- and
- modifying the set of the one or more defined parameters based on the first data and the second data.
