TiAl6V4 is one of the most commonly used titanium alloys and is characterized by high specific strength and excellent corrosion resistance. Also due to its good weldability, the titanium alloy is mostly used in the aerospace industry, in the automotive industry but also in medical technology due to its very good biocompatibility. Additive manufacturing technology, in conjunction with the titanium alloy, offers a wide range of possibilities for functional lightweight construction.

The cobalt-chromium alloy 2.4979 is particularly corrosion-resistant and at the same time biocompatible. Therefore, the alloy is particularly common for the production of implants in medical and dental technology. In addition, the material impresses with its temperature resistance and high ductility combined with equally high hardness. Due to the large proportion of cobalt in the alloy, machining presents a challenge. Therefore, processing with LPBF methods represents an ideal symbiosis between material and manufacturing process for complex component geometries.

AlMgty80 is a material system consisting of the alloying elements aluminum and magnesium. The material is therefore a cost-effective but equally value-added alternative to other aluminum alloys for the additive manufacturing process. The material is corrosion resistant, polishable and can be anodized.
