Abstract
Examples disclosed herein relate to synchronize a thermal image and a 3D print process. In one implementation, a processor synchronizes a thermal image with a step in a 3D printing process based on an occluded region detected in the thermal image. The processor may output thermal information associated with the 3D print process step.
Claims15
A system, comprising:
- a thermal camera positioned to capture thermal images of a 3D printer build area;
- a processor to:
- identify occlusion in a first thermal image captured by the thermal camera during a 3D print process based on a comparison of the first thermal image to a previously captured second thermal image;
- associate a 3D print process stage with the first thermal image based on a 3D printer movement indicated by the identified occlusion;
- and
- output information about the thermal characteristics of the 3D print process based on the associated first thermal image.
3 more elements
A method, comprising:
- comparing, by a processor, a first thermal image of a 3D print build area during a 3D print process to a previously captured thermal image to detect occlusion within the first thermal image;
- determining a first 3D print process step associated with the first thermal image based on a 3D printer movement indicated by the detected occlusion in the first thermal image;
- detecting occlusion within a second thermal image of the 3D print build area during the 3D print process;
- determining a second 3D print process step associated with the second thermal image based on a 3D printer movement indicated by the detected occlusion in the second thermal image;
- and
- outputting information about the thermal characteristics of the 3D print process based on the first and second thermal images and associated 3D print process steps.
3 more elements
A machine-readable non-transitory storage medium comprising instructions executable by a processor to:
- synchronize a thermal image in a set of thermal images with a step in a 3D printing process based on an occluded region detected in the thermal image;
- and
- output thermal information associated with the 3D printing process step.
