Bright Laser Technologies Reaches 100,000 Copper Parts Milestone — Industrial Metal 3D Printing Comes of Age

BLT Hits 100,000 Copper Parts Milestone

Bright Laser Technologies (BLT), one of China's leading metal additive manufacturing companies, has announced that its BLT-S400 platform has surpassed 100,000 units of copper alloy components in cumulative production as of March 2026. This milestone marks what the company describes as the first evidence of repeatable, industrial-grade copper additive manufacturing at scale.

Why Copper Matters

Copper is one of the most challenging materials to 3D print due to its high thermal conductivity and reflectivity, which interfere with laser-based printing processes. The BLT-S400 is an eight-laser powder bed fusion system specifically optimized for copper applications.

The 100,000th copper part was printed in March 2026, demonstrating that copper AM has moved beyond experimental prototyping into genuine production capabilities. This is particularly significant for industries like aerospace, defense, and electronics that require high-conductivity copper components.

Industrial Applications

Copper 3D printing enables:

• Heat exchangers — Complex internal geometries for better thermal performance
• Electric vehicle components — Conductive parts with optimized flow paths
• Aerospace tooling — Lightweight components with embedded cooling channels
• RF/microwave components — High-conductivity waveguides and antennas

What This Means for the Industry

BLT's milestone signals that metal AM is truly entering the production phase for copper materials. While other manufacturers have demonstrated copper printing capabilities, achieving consistent, repeatable production at this scale sets a new benchmark for the industry.

As demand for electric vehicles, renewable energy systems, and advanced electronics continues to grow, the ability to produce copper components at scale through additive manufacturing will become increasingly valuable.
