Microstructured materials as strong as steel yet less dense than water
Scientists in Germany have created a lightweight, high-quality material motivated by the system structure of bones and wood and the shell structure of bumblebees' honeycombs. Made utilizing 3d laser polymer printing consolidated with an artistic covering, the material is less thick than water however, in respect to its size, brags quality tantamount to high-execution steel or aluminum. In spite of the fact that motivated by nature, the polymer microarchitecture prepared by a group at the Karlsruhe Institute of Technology (KIT) beats its characteristic partners as far as strength/density proportion. The underlying structure was processed utilizing a methodology of 3d laser lithography or polymer printing and solidifying. Various structures were tried, including triangular, hexagonal and honeycomb. These were then covered by gas statement to give additional quality, with coatings of a fired material and alumina both tried. The polymer structure measured about 50 µm long, wi...
