2.1.1. History of 3D Printers

The conference organizers Alberto Corsín Jiménez and Adolfo Estalella state at the beginning of their invitation: “prototypes have acquired certain prominence and visibility in recent times”. (The long history of prototypes, Micheal Guggenheim,2006)

In 1920s, prototyping is become very important issue in developing manufacturing technology. Paper scales, wooden or clay models are used for describe inventors ideas. These methods are sufficient for these year but recent years, people want to constitute their ideas into being faster and more exact dimension. So, In 1980s, Rapid Prototyping technologies began to developing.

Rapid prototyping (RP) is a group of methods used to rapidly fabricate a model of a physical part or assembly using 3 D computer aided design (CAD) model. RP is construction type of a scale which usually done using 3D printing or additive layer manufacturing technology.

The first methods for RP became obtainable in the early 1980s and were used to generate models and prototype parts. The first model of 3D printing was developed by Charles Hull in 1984. Mr. Hull was an inventor of over 60 U.S. patents in the fields of ion optics and rapid prototyping. He defined stereo lithography as a method and apparatus for making solid objects by successively “printing” thin layers of the ultraviolet curable material one on top of the other.

In 1996, the world saw the first major release of 3d printers by Z Corporation. Lack of Cad software, this model cannot be used widely. In course of further development over the next decade, printer technology developed in resolution and software capability. In 2005, the first high resolution, color capab...

...ained briefly in this report. In conclusion, 3D printers will be used to begin in many areas. Despite concerns of users and governments about gun producing, many companies are already using the technology to repeatedly produce complex components of their design. As I mention, medical and automotive and aviation industries is commonly used techniques for develop their design. As 3D printers become more affordable, the small scale manufacturing will impossible to avoid use this technology which obtain them a change against large supply manufacturer for many types of product. Consumer units for home use will even become feasible, allowing end users to simply download a design for the product which they require and print it out. Because of its advantages, it will became more popular in recent year. I guess that everybody will have a 3D printer in future in their home.
