Can Binder Jetting Produce Copper Parts, and What Are Its Advantages?

Feasibility of Copper in Binder Jetting

Yes, Binder Jetting is a highly effective method for producing copper parts, especially when high electrical or thermal conductivity is required at scale. Copper grades such as Copper C101, Copper C110, and CuCr1Zr can be printed using this technology. After printing, parts undergo debinding and sintering to achieve densities above 90%, with conductivity suitable for industrial, electronics, and heat management applications.

Key Advantages of Binder Jetting for Copper

1. High Throughput and Cost Efficiency

Binder Jetting builds entire layers at once, enabling rapid print speeds ideal for batch production. It is significantly faster and more scalable than laser-based copper printing and eliminates the need for support structures, reducing post-processing time and cost.

2. Excellent Design Flexibility

The process allows for the creation of complex internal geometries, thin walls, and nested assemblies without supports. This is beneficial for printing lightweight heat exchangers, bus bars, and electronic housings with integrated cooling channels.

3. Lower Energy Consumption

Since Binder Jetting doesn’t rely on high-energy lasers or melting during printing, it consumes less energy during the build phase. Final densification is achieved through sintering, which can be optimized for batch processing.

4. Material Reusability and Reduced Waste

Unused powder remains unbound and can be recycled with minimal degradation, improving overall material efficiency—important when using high-purity copper powders.
