Abstract
Examples include an apparatus for generating a three-dimensional object. The apparatus comprises at least one energy source, at least one build layer temperature sensor, and a controller. The controller is to control the at least one energy source to pre-fuse a portion of a build layer in a build area when a build layer temperature is less than a first temperature threshold. The controller is further to, after pre-fusing the portion of the build layer, control the at least one energy source to fuse the portion of the build layer in the build area when the build layer temperature is less than a second threshold.
Claims15
An apparatus for generating a three-dimensional object, the apparatus comprising:
- at least one energy source;
- at least one build layer temperature sensor;
- and
- a controller to:
- control the at least one energy source to pre-fuse a portion of a build layer in a build area of the apparatus when a build layer temperature is less than a first temperature threshold, and
- after pre-fusing the portion of the build layer, control the at least one energy source to fuse the portion of the build layer in the build area when the build layer temperature is less than a second temperature threshold.
A method for an apparatus for generating a three-dimensional object, the method comprising:
- monitoring temperature of a build layer in the build area of the apparatus with at least one build area temperature sensor;
- when the temperature is less than a first temperature threshold, pre-fusing at least a portion of the build layer with at least one energy source;
- and
- after pre-fusing the at least a portion of the build layer and when the temperature is less than a second temperature threshold, fusing the at least a portion of the build layer in the build area with the at least one energy source.
An apparatus for generating a three-dimensional object, the apparatus comprising:
- an energy source;
- and
- a controller to:
- monitor temperature of a build layer in a build area of the apparatus to determine when the temperature is less than a first temperature threshold,
- in response to determining that the temperature is less than the first temperature threshold, control the energy source to thereby pre-fuse a portion of the build layer in the build area,
- after pre-fusing the portion of the build layer, monitor the temperature of the build layer to determine when the temperature is less than a second temperature threshold, and
- in response to determining that the temperature is less than the second temperature threshold, control the energy source to thereby fuse the portion of the build layer.
