Overview

Demonstrates enhanced reusability in PA12 nanocomposites with MWCNTs, suggesting improved part properties.

Key Points

  • To investigate the usage of MWCNTs to enhance the properties and reusability of PA12 nanocomposites in P-LPBF.
  • Preparation of nanocomposite powders with MWCNTs and end-passivated PA12.
  • P-LPBF processing with modified powder bed temperature settings.
  • Comprehensive energy density calculations performed to assess impact on part properties.
  • End-passivated PA12s showed ~90% reusability, significantly higher than open-chain equivalents.
  • Innovative process control strategies eliminated previous challenges in processing.
  • Effective Mass Energy Density (EMED) provided insights into material and process interactions.
