Overview

Observational analysis shows enhanced tensile strength in support structures with increased laser power, indicating optimal parameters for AISI 316L.

Key Points

  • Support structures become more robust as laser power increases, while high scanning speeds reduce their strength.
  • The combination of 150 W laser power and 500 mm/s scanning speed yields the highest tensile resistance in AISI 316L supports.
  • Defects were found at the interfaces of bulk and support regions, which were critical in the failure of tensile test specimens.
  • This work highlights the crucial role of processing parameters in the effectiveness of support structures in additive manufacturing.
