Grade 4, Library room. The librarian is reading to us Roald Dahl's Charlie and the Chocolate Factory. One of the rooms within the gigantic factory of Mr. Willy Wonka, the Television Room, houses his latest invention, WonkaVision. A giant chocolate bar, when placed in the contraption, is transmitted through the air in microscopic bits, only to appear in a television. This bar can be taken from the TV and even be eaten!
I think this comes really close to the idea of 3D printing.
3D printing or additive manufacturing transforms digital files to an actual solid three dimensional object by laying down successive layers of material until the entire object is created. This process allows customization of products, alleviates complexity involved in the traditional manufacturing process, is cost-, time-, and labor-efficient, and sustainable, too!
Roald Dahl was surely way ahead of his time! When he penned down the story in 1964, little did he know about 3D printing and how it would prove beneficial in the future.
Coming back to the story, Mike Teavee lets sloth get to him. His obsession with television makes him amazed at this new discovery and he attempts to send himself through television resulting in him being shrunk down to be no more than an inch high. Talk about invention, innovation and a moral for kids - all bundled in one book! :)
