Copper ETP heat exchanger

TRUMPF employs Additive Manufacturing to produce heat exchangers used for heat dissipation of electronics in their high-power laser sources. Copper, renowned for its excellent heat-conducting properties, is a valuable material for applications like heat exchangers. Utilizing AM allows for the creation of intricate geometries that enhance heat transfer efficiency. In these applications, TRUMPF uses pure copper ETP (Electrolytic Tough-Pitch) alloy. Notably, TRUMPF utilizes a “green” laser in their Laser Powder Bed Fusion process. This specific “green” wavelength demonstrates higher absorption in copper compared to typical infrared lasers, making it advantageous for their manufacturing process.
