Diabatix webinar and white paper with Amnovis

Discover how to gain 55% in cooling with DfAM of a copper 3D printed CPU cooler.

A CPU cooler with 22% better performance? We joined forces with Diabatix to develop and manufacture a novel liquid CPU cooler. The goal was to develop and manufacture a 3D printed copper cooler which is able to keep the CPU within permissible operating temperature limits. Diabatix's ColdStream provided a fully manufacturable 3D-printing custom cooler design that enhances the cooling performance by 22% while reducing the pressure drop by 15%. And Amnovis manufactured the complex copper design generated by ColdStream, delivering a high-end 3D printed component with Additive Manufacturing (AM). 

The high conductivity of copper makes it an attractive material in light of  thermal management. The copper CPU cooler with custom microchannels is designed by Diabatix through topology optimization, taking DfAM (Design for Addictive Manufacturing) rules into account. The copper 3D printing of the cooler design is challenging. We succeeded in manufacturing the cooler through our high conductivity and high strength copper 3D printing technology. Using our patented AM copper powder and proprietary production method, we provided unprecedented thermal and mechanical properties for this complex-shaped cooler component.

White paper

Find more detailed information about this fascinating collaboration that culminated in a superior copper CPU cooler in this white paper publication. The document was written by specialists from Diabatix and Amnovis. Suraj Dinkar Jadhav, Amnovis' Senior Materials Engineer: "Our copper 3D printing process supports the ability to form thin-walled and complex-shaped structures with thickness down to 200 microns. The broad processing window of this technology, ensures repeatable and reproducible build quality."
