Abstract
Examples of methods for monitoring additive manufacturing by an electronic device are described herein. In some examples, a predicted thermal image is calculated for a layer. In some examples, a captured thermal image is obtained for the layer. In some examples, a risk score is calculated for the layer based on the predicted thermal image and the captured thermal image. In some examples, a mitigation operation is performed in response to determining that the risk score is outside of a threshold range.
Claims13
A method for monitoring additive manufacturing by an electronic device, comprising:
- calculating, for a layer, a predicted thermal image;
- obtaining, for the layer, a captured thermal image;
- calculating, for the layer, a risk score based on the predicted thermal image and the captured thermal image;
- and
- performing a mitigation operation in response to determining that the risk score is outside of a threshold range, wherein the risk score is calculated with weightings based on a shape map, and wherein the weightings include a first weighting corresponding to a first area including an expanded object area and a second weighting corresponding to a second area that is complementary to the first area, wherein the first weighting is greater than the second weighting.
A three-dimensional (3D) printing device, comprising:
- a print head to print a fusing agent based on a fusing contone map and to print a detailing agent based on a detailing contone map;
- a thermal projector;
- a thermal sensor;
- and
- a controller, wherein the controller is to:
- calculate, for a layer, a predicted thermal image based on the fusing contone map, the detailing contone map, and captured thermal images of previous layers from the thermal sensor;
- obtain, for the layer, a captured thermal image of the layer from the thermal sensor;
- calculate, for the layer, a risk score based on the predicted thermal image and the captured thermal image;
- and
- perform a mitigation operation in response to determining that the risk score is outside of a threshold range, wherein the risk score is calculated with weightings based on a shape map, and wherein the weightings include a first weighting corresponding to a first area including an expanded object area and a second weighting corresponding to a second area that is complementary to the first area, wherein the first weighting is greater than the second weighting.
A non-transitory tangible computer-readable medium storing executable code, comprising:
- code to cause a processor to calculate, for a layer, a predicted thermal image;
- code to cause a processor to obtain, for the layer, a captured thermal image;
- code to cause a processor to calculate, for the layer, a risk score based on the predicted thermal image and the captured thermal image;
- and
- code to cause a processor to perform a mitigation operation in response to determining that the risk score is outside of a threshold range, wherein the risk score is calculated with weightings based on a shape map, and wherein the weightings include a first weighting corresponding to a first area including an expanded object area and a second weighting corresponding to a second area that is complementary to the first area, wherein the first weighting is greater than the second weighting.
