| Abstract Scope |
Laser scan speed is a fundamental process parameter for laser powder bed fusion (LPBF) that can be difficult to verify. For a measurement method to be feasible it must deliver accuracy, precision, and reproducibility. One approach for verifying scan speed is to measure laser scanner timing across a commanded distance. In trials of scanner timing, a bias was observed throughout time measurements. Key variables from the operating software and geometric model definition affected the magnitude of the bias. Greater awareness of these challenges can enable improved reproducibility through statistical process control. |
