Austrian sports equipment manufacturer Zweikampf is releasing their first 3D printed product on Kickstarter this week, the Zweikampf Shin Guard. They are available in three different sizes, and each pair is made from three individual layers of materials, but it is the outer 3D printed shell where the real innovations are. The unique Y honeycomb structure of the surface was designed to absorb and diffuse shocks and hits by distributing the force throughout the entire structure. At 75 grams and only 7 mm thick, the complex geometry is only possible using 3D printing.
