Now the 3D printing industry are mainly used in which areas

3D printing technology, also known as "rapid prototyping technology", "additive manufacturing technology". That is: a with the traditional material removal processing method diametrically opposed, by increasing the material, based on three-dimensional model data, usually using layer-by-layer manufacturing method, direct manufacturing and the corresponding digital model is completely consistent with the three-dimensional physical entity model of the manufacturing method. And 3d printer is a medium of 3d printing technology. 3d printer equipment can print three-dimensional model into solid. Currently 3d printing technology according to different molding principles are divided into: FDM, SLA, 3DP, SLS, etc., corresponding to the molding principle of different raw materials used as well as the application of different industries. Currently 3d printing technology is used in jewelry, footwear, industrial design, architecture, engineering and construction, automotive, aerospace, dental and medical industries, education, geographic information systems, civil engineering and other fields.

3d printers are mainly based on the size of the product they want to print, so the printer according to the size of the molding, printing accuracy, printing raw materials are different, different industries can also be targeted to choose the right 3d printer equipment for their industry.

FDM 3D printer - fused deposition molding technology, printing raw materials: plastic linear consumables PLA/ABS, equipment according to the configuration and molding size of the different prices in the thousands to tens of thousands of dollars. Disadvantages: general printing accuracy; Advantages: plastic application range is relatively wide, can be secondary processing. Is currently more popular a 3d printer. The main print size in 10mm - 1000mm products, larger can choose to splice molding.

SLA 3D printer - light-curing molding technology, printing raw materials: photosensitive resin, mostly imported machines, prices ranging from tens of thousands of dollars to hundreds of thousands of dollars. Disadvantages: brittle, not easy to save; Advantages: high printing accuracy. Suitable for printing teeth, rings jewelry and other small things.

In addition, there are also some other print printing metal powder or something, laser molding. At present, the domestic manufacturers are relatively few, imported machines and too expensive late maintenance is not convenient, so, generally, is also a large industrial enterprises to buy more.
