Abstract
3D printing technology in the industrial product design， especially the application of digital product model manufacturing is becoming a trend and hot topic。 Desktop level gradually mature and application of 3D printing devices began to promote the ri of the Global 3D printing market， Global industrial Analysis company （Global Industry Analysis Inc） rearch report predicts Global 3D printing market in 2018 will be $2。99 billion。

1 3D printing and 3D printers
3D printing and 3D printing are two entirely different concepts.3D printing is parated into different angles the picture of the red, blue two images， then the two images according to the regulation of parallax distance overprint together， using special glass to create the 3D visual effect， or after special treatment， the picture printed directly on the special grating plate， thus rendering 3D visual effect of printing technology。 And 3D printing refers to the 3D ink—jet printing technology, stacked with hierarchical processing forms， print increa step by step a material to generate a 3D entity， meet with 3D models， such as lar forming technology of manufacturing the same real 3D object digital manufacturing technology.3D printers, depending on the technology ud by its working principle can be divided into two categories:

Bad on 3D printing technology of 3D printer, by stored barrels out a certain amount of raw material powder， powder on processing platform is roller pushed into a thin layer，
then the print head in need of forming regional jet is a kind of special glue. At this time， met the adhesive will rapidly solidified powder binder， and does not meet the adhesive powder remain loo state. After each spray layer, the processing platform will automatically fall a bit， according to the result of computer chip cycle， until the real finished。 After just remove the outer layer of the loo powder can obtain required for manufacturing three—dimensional physical。

保护大自然Bad on fud deposition manufacturing technology of the working principle of 3D printer is first in the control software of 3D printers into physical data generated by CAD and treated generated to support the movement of materials and thermal spray path. Then hot nozzle will be controlled by computer according to the physical ction contour information in printed planar motion on the plane, at the same time by thermoplastic filamentous material for wire agency nt to the hot shower， and after the nozzle to add heat and melt into a liquid extrusion, and spraying in the corresponding work platform。 S
pray thermoplastic material on the platform after rapid cooling form the outline of a thickness of 0.1 mm wafer, forming a 3D printing ction。 The process cycle， load， decrea of bench height then layers of cladding forming stacked 3D printing ction， ultimately achieve the desired three-dimensional object。
2 The application of 3D printing needs
青春童话
The 3D printing technology support for a variety of materials, can be widely ud in jewelry， footwear, industrial design， construction, automotive, aerospace， dental， medical, and even food, etc。 Different areas。， according to the requirements of application targets ud by material with resin， nylon, gypsum， ABS， polycarbonate （PC） or food ingredients， etc.3D printers of rapid prototyping technology has a distinct advantage in the market, the huge potential in the production application, hot applications outlined below。
新闻题目2。1 Industrial applications
"Air cycling" is located in Bristol， UK the European aeronautic defen and Space Company using 3D printers, application of 3D printing technology to create the world’s first print bike. The bike to u as strong as steel and aluminum alloy material of nylon, the weight is 65% lighter than metal materials。 More interestingly, "air bike"， chain wheels and bearings are printed at a time， without the original manufacture parts first, and then the parts together of asmbly process， after printing， bicycles will be able to move freely。 Bicycle manufacturing process like printing discontinuous in graphic print as simple lines， 3D printer can print out the object space is not connected to each other。
2.2 Medical applications
In medicine， the u of 3D printing will two—photon polymer and biological functional materials combination modified into the capillaries, not only has good flexibility and compatibility of human body, also can be ud to replace the necrosis of blood vesls， combined with artificial organs, partly replacing experimental animals in drug developmen
t. Biotechnology in Germany in October 2011 show, Biotechnical Fair)， using 3D printers print artificial blood capillary to attract the attention of the participants, the artificial capillary has been applied in clinical medicine.
2。3 application of daily life
”3D food printer" is developed by Cornell University in New York， the United States food manufacturing equipment. The "3D food printer" ud similar routine computer printers， the working principle of ingredients and ingredients in the container (cartridge) in advance only need to enter the required recipe, by supporting the CAD software can keep the food ”print out". For many chefs, the new kitchen cooking means that they can create new dishes make food more individuality, higher food value. Using the "3D food printer" making food， from raw materials to finished products can significantly reduce the link， so as to avoid the pollution in the links of food processing, transportation, packing and so on and prervation, etc. Becau of the cooking materials and ingredients must be placed in the printer， so food raw materials must be liquid or other can ”print” state。
香水行动2。4 IT applications
Recently, a group of rearchers in Disney's u of 3D printing in the same effect with the organic glass high pervious to light plastic， at low cost to print out the LCD screen with a variety of nsors, realize the new breakthrough in the IT applications。 Using 3D printing light pipe can produce high—tech international chess； the chess pieces can detect and display the current location。 Although the monochrome screen compared with in the daily life, rich and colorful display some insignificant， but it has a 3D printing the advantages of low cost， simple manufacturing process。 In addition to the display screen, the u of 3D printing will also be able to print out a variety of nsors。 The nsors can be through the stimulation such as infrared light to detect touch， vibration, and the results output.3D printing will create more for life and wisdom city of IT applications.
