The quest for light and stiff structures by industries such as the medical industry, the aerospace industry and other industries drives the progress in the additive manufacturing technology. This article is focused on the light-weight Schoen Gyroid cellular structure, which might offer a combination of the desired mechanical properties. The goal is to preserve the lightness of a particular structure while maintaining the desired properties like the rigidity and solidity. Additive manufacturing has a high potential for producing these otherwise hard to make structures. The results published in this article are the obtained mechanical properties which depend on the strut thickness of the Schoen Gyroid cellular structures. These structures were additionally compared with a sample of coherent material from the same steel.

The aim of this article was to assess the suitability of newly applied Ni-Mo cutting steel for machinery of common steels. The biggest asset of Ni-Mo cutting steel is an easy heat treatment in comparison with other cutting tool materials. The Ni-Mo cutting steel heat treatment saves time and lowers demands on the thermal procedure. The Ni-Mo cutting steel was exposed to a cutting test and the result of these test was compared with the common tool steel DIN S 6-5-2 (W.Nr. 1.3343). Non-contact optical metrology system IFM G4 was used for determining the wear of cutting tools. The results proved an affinity of Ni-Mo steel to machined material. Therefore measures have been accepted to suppress this property.
