The 3D printer, also known as a three-dimensional printer, is a cumulative manufacturing technique that creates three-dimensional objects by printing a layer of bonding material. At this stage the three-dimensional printer is used to make samples. Since 2003, sales of three-dimensional printers have grown and prices have begun to fall.
The technology can be used in jewelry, footwear, industrial design, construction, engineering and Construction (AEC), automotive, aerospace, dental and medical industries, education, geographic information systems, civil engineering, and many other areas.
3D Printer Working step is this: Use CAD software to create items, if you have a ready-made model can also, such as animal models, people, or miniature buildings and so on.
Then the SD card or USB flash drive to copy it to 3D printer, printing settings, the printer can print them out, its work structure breakdown diagram is as follows.
The working principle of 3D printer is basically the same as the traditional printer, which consists of control components, mechanical components, print heads, consumables and media, and the printing principle is the same. 3D printer is designed on the computer before printing a complete three-dimensional model, and then print output.
3D Printing and laser molding technology, the use of layered processing, overlay molding to complete the 3D entity printing. Each layer of the printing process is divided into two steps, first in the area of need to spray a layer of special glue, glue droplets itself is very small, and not easy to diffuse.
Then spraying a layer of uniform powder, the powder encountered glue will quickly solidify bonding, and no glue area remains loose. In this way a layer of glue in a layer of powder alternately, the solid model will be "printed" molding, after printing, as long as the removal of loose powder can be "planing" the model, and the remaining powder can be recycled.
3D printers can be applied to any industry, as long as these industries need models and prototypes. Objet, a company in Israel, believes that 3D printers are in great demand in sectors such as government, aerospace and defense, medical equipment, technology, education and manufacturing.
Medical industry. A 83-year-old man with a chronic bone infection, so replaced by 3D printer "print" Out of the jawbone, this is the world's first use of 3D printing products to do the human skeleton case.
Bone Print according to foreign media reports, in the near future surgeons may be able to use print equipment to print out various sizes of bones for clinical use in surgery. This magical 3D printer has been created, and the printing material used to replace the real human skeleton is being tested.
