Abstract
According to an example, an apparatus may include an image capture device, a controller, and a computer readable storage medium. The computer readable storage medium may include instructions that may cause the controller to receive, from the image capture device, an image of a testing agent deposited in a testing pattern onto a layer of build materials, in which the layer of build materials is to form a section of a three-dimensional printed part. The instructions may also cause the controller to determine a condition of the deposited testing pattern in the received image, wherein the determined condition is to be used to determine a quality level of the layer of build materials based upon the determined condition.
Claims13
An apparatus comprising:
- an image capture device;
- and
- a controller;
- a computer readable storage medium on which is stored instructions that are to cause the controller to:
- receive, from the image capture device, an image of a testing agent deposited in a testing pattern onto a fusing agent that has been deposited onto a layer of build materials, wherein the layer of build materials is to form a section of a three-dimensional printed part, wherein the fusing agent has a radiation absorbing property, wherein the build materials on which the fusing agent and the testing agent have been deposited have undergone a fusing operation, and wherein the received image is an image of the deposited testing pattern following the fusing operation;
- and
- determine a condition of the deposited testing pattern in the received image, wherein the determined condition is to be used to determine a quality level of the layer of build materials.
A method for determining a quality level of a layer of build materials, said method comprising:
- depositing a fusing agent in areas of the layer of build materials that are to be fused together;
- depositing a testing agent in a testing pattern onto an area of the layer of build materials;
- applying radiation to fuse the build materials in the areas of the layer of build materials on which the fusing agent and the testing agent have been deposited;
- receiving an image of the testing agent deposited in the testing pattern onto the layer of build materials, wherein the layer of build materials forms a section of a three-dimensional printed part, wherein the received image of the deposited testing agent is captured following application of the radiation;
- determining a condition of the deposited testing pattern in the captured image;
- and
- outputting the determined condition of the deposited testing pattern, wherein the quality level of the layer of build materials is to be determined from the determined condition.
A non-transitory computer readable medium on which is stored machine readable instructions that when executed by a processor, cause the processor to:
- receive an image of a testing agent deposited in a predetermined arrangement onto a fusing agent that has been deposited onto layer of build materials, wherein the layer of build materials is to form a section of a three-dimensional printed part, wherein the fusing agent has a radiation absorbing property, and wherein the build materials on which the fusing agent and the testing agent have been deposited have undergone a fusing operation;
- determine a condition of the deposited predetermined arrangement from the received image;
- and
- output the determined condition of the deposited predetermined arrangement, wherein a quality level of the layer of build materials is to be determined from the determined condition.
