My Life in 3D
If we would have been asked at the end of the 70s if it could be possible a printer reproducing objects in three dimensions, just right after the first IBM computer came out and marked the beginning of a new technological era, definitely we would have replied: of course not.
Four decades later, it became a reality. 3D printing has come out from laboratories and although it isn’t as popular as inkjet or laser printers, everything point that it is just a matter of time until price and operating costs go down at prices that people can afford.
3D printing is a technique that allows us to create any design with height, width, and length from a previously created design saved in a computer or directly downloaded from the Internet, through a device called 3D printer. It can create objects such as clothes, tools, houses, spare parts, medical equipment, food, and even organs for the human body.
The main difference between the printers we know, as the Inkjet and the laser printers, is that instead of injecting ink through their nozzles, they inject a special molten plastic, which immediately dries once expelled, forming the wanted figure with high precision. It's a device designed to create three-dimensional solid physical bodies by adding layer to layer of a material, usually PLA or ABS thermoplastics, but also resins, photopolymers. So, without needing any mold, it allows us to create an object we can take in our hands.
The automotive industry, jewelry, and the construction sector have found significant savings in this technology due to the reduction in molding times for different processes, mainly, for the spare parts production.
Another difference between conventional ways of producing objects and 3D printing is that in the first method, you'll have to remove amounts you don't need to mold the final product, while in 3D printing only the necessary material is used, which means significant savings and less pollution.
