The new neubau frames feature the latest 3D printing technology using 100% organic material. The frames are printed using a material based on castor beans. For the first time a metal inlay is integrated in the 3D printed temples, so that they can be adjusted without heat and stay in shape permanently. A newly developed surface finish prevents the risk of bleeding out and fungi while also creating a smooth tactile grip. This, together with the compact logo-hinge, makes for a bold and super-lightweight frame.
