3D Printer, Which Make Anything True
What is 3D printer? Is it true? Nowadays, not anyone knows about this new technological machine, and some people think that is very far away from their daily life. However, the fact that it is opposite, “3D printing is any of various processes used to synthesize a three-dimensional object”(Joe, 2013). “In 3D printing, additive processes are used, in which successive layers of material are laid down under computer control”(Pirjan &Petrosanu). A 3Dprinter is a type of industrial robot. In other words, 3D printer is a type of industry robot. 3D printing is a technology, which makes it possible to build real objects from virtual 3D objects. “This is done by “cutting” the virtual object in 2D slices and printing the real object slice by slice. Slices are printed on top of each other and since each slice has a given thickness, e.g. 0.5mm, the real object gains volume every time a slice is added”(Createitreal, 2015).
Metal and plastic are the basic materials for 3D printer. With the progress of science and technology, there are some new materials came out, such as ABS plastics and photopolymers, offer greater flexibility and robustness to help 3D printers create a wider variety of objects. What can they do? That is a good question, they cannot be eaten, but they can help you make something to eat. For example, if you are preparing dinner tonight, you won’t need to do any chopping or peeling — ingredients just go straight into your kitchen fabricator. 3D printer makes the dream much easier to achieve, some husbands who want give a gift to their wives for anniversary. Even they are not very rich, they can design a special jewelry and make it for their wives. These accessories are unique, representing their unique and lasting love, it is very meaningful! It is not very far away from us, people can buy 3D printer in restore and shop online.
Finally, it seems like that people can use 3D printer to print anything you want could be as easy as pushing a button.
