Imaging devices for use with additive manufacturing systems and methods of imaging a build layer

An additive manufacturing system comprising:

• a material for forming a component;
• and
• an imaging device comprising:
• a light source comprising a plurality of LED lights, said plurality of LED lights comprising a first portion of LED lights positioned at a first angle relative to a build layer within the material and a second portion of LED lights comprising a first array positioned at a second angle relative to the build layer and a second array positioned at a third angle relative to the build layer, said plurality of LED lights configured to highlight a contoured shape feature of the build layer, wherein the first angle is a right angle, and wherein the second angle and the third angle are acute angles;
• a high resolution imaging bar displaced from the material along a first direction and extending along a second direction, said high resolution imaging bar comprising a first end and a second end opposite said first end, said light source coupled to said high resolution imaging bar, said first array positioned adjacent said first end and said second array positioned adjacent said second end, wherein said high resolution imaging bar is configured to generate an image of the build layer, said high resolution imaging bar comprising:
• at least one detector array;
• and
• an imaging element positioned between said at least one detector array and the material.

A method of imaging a build layer of a material within an additive manufacturing system, said method comprising:

• positioning an imaging device including a high resolution imaging bar such that the imaging device is displaced from the material in a first direction and extends along a second direction, the high resolution imaging bar including at least one detector array and an imaging element positioned between the at least one detector array and the material, the high resolution imaging bar having a first end and a second end opposite the first end;
• lighting the build layer using a light source coupled to the high resolution imaging bar, wherein the light source includes a plurality of LED lights, including a first portion of LED lights positioned at a first angle relative to the build layer and a second portion of LED lights including a first array positioned at a second angle relative to the build layer and a second array positioned at a third angle relative to the build layer, the first array positioned adjacent the first end and the second array positioned adjacent the second end, the plurality of LED lights configured to highlight a contoured shape feature of the build layer, wherein the first angle is a right angle, and wherein the second angle and the third angle are acute angles;
• moving the imaging device along a third direction;
• and
• generating an image of the build layer.
