Enhancing vibration damping through controlled porosity in PBF-LB/M-manufactured parts: an experimental investigation

Key Points

• Enhanced vibration damping is observed with increased controlled porosity in manufactured parts.
• A significant 30% increase in vibration damping effectiveness was recorded in tests of PBF-LB/M components.
• Experimental investigation on vibration response was conducted using varying levels of controlled porosity in parts.
• Findings indicate potential benefits for engineering applications requiring optimized damping properties.
