To understand 3D printing, it is helpful to compare it with regular ink-paper printing. Did you know that with regular printers, the ink does not stain the paper? It actually sits on the paper or is “bonded” to it. In the case of 3D printing, ink is replaced by different materials such as functional plastics, metals, ceramics, sand and even biological materials like sugar and chocolate.
3D printing is also referred to as additive manufacturing - the processes by which a physical object is created by adding material layer by layer. We've handpicked the resources in this unit to give you the best overview- from input to output- that will shed some light on how something as mind-blowing as 3D printing actually works!
