LZH | The IMA Award of Excellence 2016 goes to Dr. Matthias Gieseke from the Laser Zentrum Hannover e.V. (LZH) for his work on the additive manufacturing of magnesium components by Selective Laser Melting (SLM®). His findings have significantly improved the quality of the parts.

The International Magnesium Association (IMA) recognizes scientific-technical advances in magnesium-based technologies, products and processes on an annual basis. Dr. Gieseke received this year’s award in the category "processes".

Magnesium is very well suited for lightweight construction and medical applications. Due to the high reactivity of magnesium, however, the pure metal powder oxidizes quickly. The low vaporization temperature of magnesium leads to process emissions that pollute the processing chamber and have a negative effect on the process. In addition, undesired particles adhere to the surface. By adapting the manufacturing parameters and carefully selecting the alloys used, Dr. Matthias Gieseke minimized these undesired effects.

Thus, the quality of SLM-manufactured magnesium parts can be increased significantly, and the additive manufacturing of parts made of magnesium or magnesium alloys with SLM can now be transferred into an industrial process.
