Introduction to 3D printing technology

Last news about 3D Printing -Cyber security Risks In 3D Printing

The first 3D printing general electric commercial jet engine, has been certified by the Federal Aviation Administration of the United States.Scientists found that 3D printing in the direction of printing and insertion, there are network security impact.They reported that the orientation of the product during 3D printing could make as much as a 25 percent difference in its strength.And economic concerns also influence how a manufacturer prints a product.Due to the existence of this problem, 3D printed parts, such as metal molds use in injection molding for high temperature and pressure conditions, may eventually lead to failure of product development.This may be a good thing for all injection mold manufacturers, should be for the company’s business will not give too much to steal 3D printing, is a rapid prototyping technique, which is a digital document based on the model, it was used powdered metal or plastic materials and bonded by the printed layer by layer technology way to construct the object.

3D printing materials are usually printers using digital technology to achieve. Often in the mold manufacturing, industrial design and other fields are used to make the model, and then gradually for direct manufacturing of some products, there have been made using this technique to print parts. The technology in the jewelry, footwear, industrial design, architecture, engineering and construction (AEC), automotive, aerospace, dental and medical industries, education, GIS, civil engineering, guns, and other fields have applied.

Everyday life of ordinary printer can print flat items used computer design, and the so-called ordinary printers and 3D printer works basically the same, but somewhat different printing materials, printing materials are ordinary printer ink and paper, while the 3D printer built with metal , ceramic, plastic, sand and other different “printed materials”, are real materials, the printer connected to the computer through computer control can be “printed material” layer laminated together, eventually became the blueprint on your computer kind. In layman’s terms, 3D printer can “print” of a 3D object in real devices, such as printing a robot toy car printing, printing of various models, and even food, etc.. The reason colloquially called “printer” is a reference to the technical principles of ordinary printer, because the process of layering and ink-jet printing process is very similar. The three-dimensional printing technology called 3D printing technology.

There are many different 3D printing techniques. They differ in the way that the material is available, and to create build parts with different layers.

[3] 3D printing materials are commonly used in fiberglass nylon, durable nylon material, gypsum materials, aluminum, titanium, stainless steel, silver, gold, rubber-like material.

3D printing technology is not used in mass production, so some experts advocate 3D printing is the third industrial revolution, this argument is just agimmick. Foxconn OEM for Apple iPhone has been for many years. Gou made with 3D printing phones to illustrate 3D printing products can not only see, because we can not add electronic components, electronic product scan not be produced as the amount of these products. 3D printing even without the production of electronic products,but by material constraints,other products can be produced very little, “even if the products produced, can not mass production, but also on the broken Yishuai.
“3D printing is indeed more suitable for some small-scale manufacturing,especially high-end customized products, such as auto parts manufacturing, although the main material is plastic, but the future of metallic materials will certainly be applied to 3D printing in the past,” said Crump, 3D printing technology has entered the dental, jewelry, medical industry,the scope of future applications will be more widely available.
