3D Printing: 3D Printed Tubulanes As Lightweight Hypervelocity Impact Resistant Structures (small 52/2019)

This cover shows Tubulane structures made up of bio-degradable soft polymer created by 3D printing. It can handle ballistic impact. The bullet stops in the second layer of the tubulane structure with no significant structural damage while bullet fire with the same speed propagates the crack through the whole reference cube. More details can be found in article number 1904747 by Douglas S. Galvão, Chandra Sekhar Tiwary, Pulickel M. Ajayan, and co-workers.
