Abstract Scope Based on industrial screen printing technology, a 3D screen-printing process has been developed that offers interesting features for the additive manufacturing of metallic high-precision parts. The applied printing paste is applied layer-by-layer and is highly loaded with metallic particles. Once the printing process is completed, a heat treatment is carried out which removes the binder and eventually leads to dense metallic parts by sintering of the powder particles. 3D screen printing of fin-type heat exchangers from copper was investigated. The goal was to manufacture a compact water-air heat exchanger with a very small distance between the individual fins in one step. It was possible to include the manifold for the water circuit into the print and realize a fin thickness of 200 Ám and a fin spacing of 200 Ám. Furthermore, special care was taken to avoid swelling during debindering and minimize distortion during sintering.
