Engineers 3D print shape-shifting smart gel

Feb 2, 2018 United States
Engineers have invented a "4D printing" method for a smart gel that could lead to the development of "living" structures in human organs and tissues, soft robots and targeted drug delivery.
Bugatti 3D prints world's largest functional titanium car component

Bugatti 3D prints world's largest functional titanium car component

Jan 26, 2018 France
For the first time, the Bugatti developers have succeeded in designing a brake caliper that can be produced by 3-D printing. But that is by no means all. While the main material used for the additive production of vehicle components to date has been aluminium, the new brake caliper is made from titanium.
