This disclosure describes various system and methods for monitoring photons emitted by a heat source of an additive manufacturing device. Sensor data recorded while monitoring the photons can be used to predict metallurgical, mechanical and geometrical properties of a part produced during an additive manufacturing operation. In some embodiments, a test pattern can be used to calibrate an additive manufacturing device.

In an example implementation, a sintering system includes optical fiber installed into a sintering furnace. A support structure inside the furnace is to support a token green object in a predetermined position and to hold a distal end of the fiber adjacent to the predetermined position. A light source is operably engaged at a proximal end of the fiber to transmit light through the fiber into the furnace. A light detector is operably engaged at the proximal end of the fiber to receive reflected light through the fiber that scatters off a surface of the token green object.

Embodiments of the present disclosure generally relate to methods for detecting end-points of cleaning processes for aerospace components containing corrosion. The method includes exposing the aerospace component to a first solvent, exposing the aerospace component to a first water rinse, and analyzing a first aliquot of the first water rinse by absorbance spectroscopy to determine an intermediate solute concentration in the first aliquot, where the intermediate solute concentration is greater than a reference solute concentration. The method further includes exposing the aerospace component to an aqueous cleaning solution to remove corrosion from the aluminum oxide layer, exposing the aerospace component to a second solvent, and exposing the aerospace component to a second water rinse, and analyzing a second aliquot of the second water rinse by absorbance spectroscopy to determine a post-clean solute concentration in the second aliquot, where the post-clean solute concentration is less than the intermediate solute concentration.
