How Does 3D Printing Actually Work and What Can You Make?

Three-dimensional (3D) printing, also known as additive manufacturing or rapid prototyping, is the process of creating three-dimensional objects from digital files. Working on one layer at a time, 3D printers can create complex shapes at a speed that rivals traditional manufacturing methods. A short list below shows what 3D printers can make and scientists are already working on making human organs and skin:
