3D printing technology and its application Paul G
Abstract
万能角钢
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 rise of the Global 3D printing market, Global industrial Analysis company (Global Industry Analysis Inc) research report predicts Global 3D printing market in 2021 will be $2.99 billion. Keywords: 3D printing; Application; Trend 1 3D printing and 3D printers
贴片三极管 3D printing and 3D printing are two entirely different concepts.3D printing is separated 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 glasses 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 increase step by step a material to generate a 3D entity, meet with 3D models, such as laser forming technology of manufacturing the same real 3D object digital manufacturing technology.3D printers, depending on the technology used by its working principle can be divided into two categories: 1.1 3D printer based on 3D printing technology
Based 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 po
wder remain loose state. After each spray layer, the processing
擀筋棒 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 loose powder can obtain required for manufacturing three-dimensional physical.
1.2 3D printers based on fused deposition manufacturing technology
Based on fused 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 section contour information in printed planar motion on the plane, at the same time by thermoplastic filamentous material for wire agency sent to the hot shower, and after the nozzle to add heat and melt into a liquid extrusion, and spraying in the corresponding work platform. Spray thermoplastic material on the platform after rapid cooling form the outline of a thickness of 0.1 mm wafer, forming a 3D printing section. The process cycle, load, decrea
se of bench height then layers of cladding forming stacked 3D printing section, ultimately achieve the desired three-dimensional object.
气泵接头 2 The application of 3D printing needs
The 3D printing technology support for a variety of materials, can be widely used in jewelry, footwear, industrial design, construction, automotive, aerospace, dental, medical, and even food, etc. Different areas., according to the requirements of application targets used 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. 2.1 Industrial applications
\cycling\is located in Bristol, UK the European aeronautic defense and Space Company using 3D printers, application of 3D printing technology to create the world's first print bike. The bike to use as strong as steel and aluminum alloy material of nylon, the weight is 65% lighter than metal materials. More interestingly, \chain wheels and beari
ngs are printed at a time, without the original manufacture parts
first, and then the parts together of assembly 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 use 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 used to replace the necrosis of blood vessels, combined with artificial organs, partly replacing experimental animals in drug development. Biotechnology in Germany in October 2021 show, Biotechnical Fair), using 3D printers print artificial blood capillary to attract the attention of the participants, these artificial capillary has been applied in clinical medicine.
2.3 application of daily life
\University in New York, the United States food manufacturing equipment. The \food printer%used 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 \out\For many chefs, the new kitchen cooking means that they can create new dishes make food more individuality, higher food value. Using the \products can significantly reduce the link, so as to avoid the pollution in the links of food processing, transportation, packing and so on and preservation, etc. Because of the cooking materials and ingredients must be placed in the printer, so food raw materials must be liquid or other can \2.4 IT applications
