Can you name the promising future technology nowadays? You can say many things such as flying cars, working robots, and AI. Among them, 3D printing is one of the most important future technologies. It has changed our life into tangible ones. If you have anything to have, you just draw the first sketch and make it real through printing, which means people can make whatever they want in the future without taking some time and making an effort. Since this amazing technology was created in 1981, Nagoya institute of industrial research, Japan, we have used and experienced 3D printing.

The 3D printer is the closest machine to 3D printing, and it makes things by laid melted materials by moving the X, Y, and Z axes. Most printers are used at people's homes, and individuals use plastic as the main ingredient, but it does not mean that printers use only plastic as materials. Depending on the type of printer, printers are possible to use different materials, like iron and glass that we well know. 3D Printing Material Developer, Mark forged CEO Greg Mark said that they made the materials hard by adding carbon to the existing plastic. So, it can fly but it is very strong.

Why has 3D printing become one of the most important future technologies? It is because we can make things by modeling and printing at a lower price. 3D printing export, MakerBot CEO Bre Pettis said that design and manufacture taking a few days. So, innovation speed is quick. A 3D printers can use for medical purposes, for example, printing people's teeth and bones, and transplanting instead of broken or unusable. It can also print people's organ models and then use them to determine how and where to operate.

However, 3D printers can be abused by people. A 3D printer that can print things with modeling files is beneficial, but sometimes it can be bad. If the file of the gun has distributed, downloaded, and printed, then you can use the gun. The printer that is used in the house or by an individual uses plastic as the main material, so you can take it to other countries because metal detectors cannot find this gun. This gun is made up of plastic, so nobody can detect it.

The 3D printer has been developing, so there are many jobs in 3D printing. We are able to get 3D printers at a cheap price. 3D printing is one of the most important technologies, so we learn how to use it, and it can be useful to get jobs in 3D printing. Using 3D printing is beneficial, but not abusing 3D printing is important.
