Metal 3D Screen Printing is a sinter-based metal additive manufacturing technique that utilizes a printable suspension of metal powder and a binder and the screen printing process. This layer-on-layer printing is repeated until a three-dimensional part is manufactured. A first heat treatment is applied to remove the organic binder; subsequently the remaining metal powder is sintered to structures with high precision and good mechanical stability. The residual minimal wall thickness and channel width amounts about 100 µm. In contrast, the maximal structure height may add up to a couple of centimeters. Hence, exceedingly high aspect ratios are feasible. The method enables the production of three-dimensional structures with horizontal apertures or closed channels. The 3D Metal Screen Printing process allows for high resolution production of high volume production of components that are not realizable at all or only at very high costs compared to conventional methods.
