From 99.95% Purity to Custom Parts – Advancing Thermal & Electrical Performance

In industries demanding uncompromising thermal and electrical conductivity, pure copper (≥99.95% Cu) stands unrivaled. However, its high laser reflectivity (over 90% for infrared lasers) and rapid heat dissipation have long made pure copper 3D printing a technical challenge. XiaoJiao has mastered this complex process, delivering pure copper components that redefine performance standards in electronics, aerospace, and energy sectors.

Why Pure Copper 3D Printing Outperforms Alternatives

Pure copper’s unique properties—thermal conductivity up to 398 W/m·K and electrical conductivity of 101% IACS—make it irreplaceable in high-performance applications. Unlike copper alloys (which sacrifice conductivity for printability), 3D printed pure copper retains these traits while offering:

· Design Freedom: Intricate structures (e.g., 0.1mm micro-channels, lattice heat sinks) impossible with machining.

· Material Purity: 99.95%+ copper content, avoiding alloying elements that reduce conductivity.

· Performance Consistency: Uniform grain structure from additive manufacturing, eliminating defects in cast or forged pure copper.

XiaoJiao’s Breakthroughs in Pure Copper 3D Printing

Overcoming pure copper’s print challenges requires specialized technology—areas where XiaoJiao leads:

· Blue Laser Technology: 515nm wavelength lasers boost copper absorption rate to 45% (vs. 10% for standard infrared lasers), ensuring full melting and 99.9%+ part density.
