A 3D shape with all straight edges and flat faces ... This is shown in the formula \(E\) = \(V\) + \(F\) – 2 The flat surface of a cube is a face. Each face of a cube is a square.

the 3D-printing process allowed the researchers to create complex shapes that could be customized in manufacturing applications. To demonstrate the proof-of-concept, they produced foam in the ...

Recyclable plastic objects can be 3D-printed using light 1. 3D printing can quickly make objects with complex shapes. But recycling those products into ones that are equally tough is a challenge.
