Scientists from The Hebrew University of Jerusalem have created wood ink that can be extruded into flat wooden structures, self-morphing into complex 3D shapes as they dry and shrink. The researchers ...

Wood shavings have been turned into 3D printer ink to make objects that start off as damp, flat sheets and then twist and warp into shape as they dry. This method of 3D printing could make wood sturdy ...

3D shapes can be made from 2D shapes called nets. Watch the video to learn how 3D shapes, such as a cube, can be created from nets, an arrangement of 2D shapes. Let's talk about nets. More ...

A 3D shape with all straight edges and flat faces is a polyhedron. Other 3D shapes with least one curved surface are not polyhedra. A 3D shape with regular polygonal faces, meeting at equal angles, is ...
