21st Century Technology

The technology I want to talk about is 3D printing. I think it is amazing how far 3D printing has gotten this day and age, with devices that can make largescale creations or even little pens that allow for freehand creation. It is crazy to think of where this technology started, as humanity once only thought we could create prints in 2D. We could go all the way back and talk about the early days, where paper was invented in China in AD 105. People were only able to use ink to hand write their messages and texts. Paper evolved from parchment to scrolls, then to books. Then we could flash forward to the creation of the printing press by Johannes Gutenberg in 1440. Now we were able to use the press to make many copies of texts and distribute them to the populace. Over time this device got more advanced, and now most people own a printer in their own home. Finally, we made it to around today, where we have printers that can print not on paper, but instead an object from code input to a computer. It is amazing to think of the possibilities that this technology could produce once humanity gets a deep understanding of it. Organs could be produced for patients at hospitals, industry production would increase, almost anything we can think of. I bet one day everyone might have a 3D printer in their house that could even print organic material like food. The concepts are there, all we need is the evolution and development of 3D printers for it to happen.
