| Abstract Scope |
The coaxial photodiode signal collected during laser powder bed fusion printing on our GE M2 series 4+ machine, has become important for multiple projects related to building feed forward models, predicting defects and optimizing parameters. To help justify our heavy use of this sensor data, more than a thousand single tracks were generated on titanium, stainless steel and aluminum, while varying power, speed and spot size. The experiment was then repeated after a year of time. We will report the trends in sensor data observed across these parameters, like increasing signal with laser power, decreasing signal with scan speed, and an unexpected, peaked signal with spot size, and the variation from the two, time separated experiments.
