Copper 3D Printing Services

Copper’s high thermal conductivity makes it difficult to process as heat dissipates quickly from the melt pool. This requires specialized laser systems with higher power and optimized parameters. Our advanced DMLS equipment and process expertise enable successful production of dense, high-conductivity copper parts.

Our pure copper parts achieve 90-100% IACS electrical conductivity and thermal conductivity up to 400 W/m·K. Post-processing heat treatments can optimize properties. We provide conductivity test reports with all copper components to verify performance specifications.

Yes, copper 3D printing excels at creating conformal cooling channels that follow part geometry for optimal heat transfer. This is ideal for injection mold inserts, heat exchangers, and electronics cooling where traditional machining cannot achieve the desired cooling efficiency.

We offer pure copper (99.9% Cu) for maximum conductivity and CuCrZr alloy which provides higher strength while maintaining 80% of pure copper’s conductivity. The alloy is ideal for applications requiring both good conductivity and mechanical strength. We help select the optimal material for your requirements.

Surface finishes include as-printed, machined, polished, electroplated (nickel, tin, silver), and chemical treatments. For electrical contacts, we can provide specific surface treatments to minimize contact resistance. Protective coatings prevent oxidation and maintain conductivity over time.

Copper 3D printing enables complex internal geometries like conformal cooling channels impossible with traditional manufacturing. It eliminates brazing joints that reduce thermal efficiency. While material costs are higher, the ability to optimize heat transfer paths and consolidate assemblies often provides superior performance and cost savings for thermal management applications.
