High conductivity high strength copper 3D printing

Using our proprietary powders and patented production method, we provide unprecedented thermal, electrical and mechanical properties for complex-shaped heat and electrical conduction components.



Our approach

At Amnovis, our copper and copper alloy 3D printing approach is built on a deep understanding of the laser powder bed fusion process. We developed a unique technology that allows us to produce high-end copper components with Additive Manufacturing using our mature 3D printing technology without the use of green or high-power lasers. This unique approach leads to unique properties:

  • Improved electrical and heat conductivity; electrical conductivity up to 90% IACS

  • Improved mechanical performance; ultimate tensile strength up to 500 MPa

  • High material density (>99%)

  • Tunable conductivity and mechanical properties

  • Robust and reliable results thanks to a broad processing window

  • Copper alloy powders with excellent flowability and resistance against oxidation

Your benefits

  • Unprecedented combination of thermal and electrical conductivity and mechanical strength

  • High feature resolution; wall thickness below 200 micrometer (0.0078 inch)

  • Potential for weight reduction and material consumption by design for AM

  • Single step-process with immediate part strength and without debinding or sintering

  • Our approach has been validated with well-known alloys like CuCr1Zr

  • More than 6 years’ experience in copper 3D printing

Applications

We support our customers with the development and manufacturing of high thermal and electrical conductivity components like:

  • Heat dissipation and exchange components; cool plates, heat sinks, heat pipes, heat exchangers, CPU and datacenter cooling devices, conformal cooling mold inserts, etc.

  • Electrical conductivity components; induction coils, EV motor windings, electromagnetic coils, waveguides, and antennas, etc. 

  • Space propulsion systems; rocket engines components

Other applications

Our approach has unique benefits for Directed Energy Deposition (DED) and 3D laser cladding applications too. Besides, we can possibly apply our proprietary and patented approach to your specific copper alloy.
