Cu 3D Printing: Unleashing Copper's Potential in Additive Manufacturing

Why Cu 3D Printing Stands Out in Metal Additive Manufacturing

Copper (Cu) is a material powerhouse—boasting 98% IACS electrical conductivity, 401 W/m·K thermal conductivity, and exceptional ductility. Yet, its unique properties (high laser reflectivity, thermal conductivity) made it a "difficult metal" for 3D printing until recent advances.

 


Cu 3D printing changes this narrative by overcoming traditional manufacturing limits:

l Design Freedom: Unlike CNC machining, 3D printing creates Cu parts with internal lattices, micro-channels (≤0.5mm), and conformal geometries—critical for heat sinks and high-frequency coils.

l Performance Preservation: Additive manufacturing retains copper's natural conductivity, outperforming cast or welded Cu parts (which lose 5-10% conductivity due to impurities).

l Material Efficiency: 3D printing uses 70% less Cu than subtractive methods, aligning with sustainability goals in aerospace and EV industries.

 

For engineers, Cu 3D printing isn't just a process—it's a way to maximize copper's inherent advantages in high-performance systems.
