Standard Practice for Additive Manufacturing — Powder Bed Fusion — Condition-Defined Maintenance for Optical Systems

Importancia y uso:

4.1 The overall objective of this practice is to provide recommendations for the systematic acquisition of image data that indicate the health condition of the wear-sensitive SPW in PBF-LB/M machines. These data may allow a user to determine calibration and maintenance cycles based on the actual health condition of the SPW.

4.2 The recommendations are intended for original equipment manufacturers (OEMs) of PBF-LB/M machines to provide guidance for the implementation of sensor systems to acquire spatially resolved data about the health condition of the SPW.

4.3 The recommendations are intended for users of PBF-LB/M machines to provide guidance for the assessment of the actual health condition of the SPW to:

4.3.1 Flag when a calibration or maintenance of the optical system is needed and alert the user or OEM to perform the calibration or maintenance and

4.3.2 Generate statistical estimates for the useful life, or critical health state, of the SPW based on data recorded over the long term. The statistics may be used to derive maintenance cycles that allow a better utilization of the useful life of the SPW than current predetermined maintenance cycles.
