Analysis of Melt Pool Monitoring Data for Evaluation of Material Properties and Process Stability in LMD#

How to analyze and correlate LMD melt pool monitoring data in a geometry-oriented approach with material properties?

 

Challenge and Motivation

  • Thermal process control in LMD is strongly influenced by process parameters and part geometry.
  • Systematic correlation between melt pool data and material properties has not yet been little studied for AM specimen.
  • Correlation is to be enabled by spatially resolved data acquisition and geometry-oriented analysis.

Objective

  • Complementation of melt pool temperature data with melt pool image KPIs.
  • Methodology for geometry-oriented measurement data analysis.
  • Correlation of measurement data & material properties.
