Abstract
In one example in accordance with the present disclosure, a method is described. The example method determining parameters for a pulsed laser to generate a melt pool pattern in a three-dimensional (3D) object to produce different phases in the 3D object that vary according to the melt pool pattern. The example method also includes controlling the pulsed laser to form the 3D object in an additive manufacturing process based on the determined parameters and the melt pool pattern.
Claims15
A method, comprising:
- determining parameters for a pulsed laser to generate a melt pool pattern in a three-dimensional (3D) object to produce different phases in the 3D object that vary according to the melt pool pattern;
- and
- controlling the pulsed laser to form the 3D object in an additive manufacturing process based on the determined parameters and the melt pool pattern.
A method, comprising:
- generating a first melt pool in a first region of a build material with a pulsed laser set to a first set of parameters to control phase properties in the first region;
- adjusting the pulsed laser to a second set of parameters;
- and
- generating a second melt pool in a second region of the build material with the pulsed laser set to the second set of parameters to produce phase properties in the second region that differ from the phase properties in the first region.
An additive manufacturing system, comprising:
- a build material distributor;
- a pulsed laser;
- a controller;
- and
- a non-transitory computer readable medium having stored thereon computer executable instructions to cause the controller to:
- utilize the build material distributor to dispense the build material in a plurality of layers;
- and
- control the pulsed laser to generate a melt pool pattern in the plurality of layers of the build material to form a three-dimensional (3D) object having different phases that vary according to the melt pool pattern.
