3D Printing
3D printing technology is a rapid prototyping technology, is based on a mathematical model file, the use of powdery metal or plastic and other adhesive materials, through the layer by layer to build the way the object technology. Often in the mold manufacturing, industrial design and other fields are used to manufacture the model, after the gradual use of some products for the direct manufacture, has been used to print out the use of this technology components. The technology is used in jewelry, footwear, industrial design, construction, engineering and construction (AEC), automotive, aerospace, medical industry, education, geographic information systems, civil engineering, firearms and other fields.
Principle: DLP equipment contains a resin can accommodate the tank, can be placed in a specific wavelength of UV light can be cured after the resin, DLP imaging system placed under the tank, the imaging surface is located in the bottom of the tank, through the Energy and graphics control, each can cure a certain thickness and shape of the thin layer of resin (the layer of resin and the front section of the cross-sectional profile is exactly the same). A pulling mechanism is arranged above the tank, and each time the cross-sectional exposure is completed, a certain height is raised (the height is the same as the thickness of the layer), so that the solidified resin which is currently solidified and separated from the bottom of the tank and bonded to the puller or On the last molding of the resin layer, so that by layer exposure and lift to generate three-dimensional entities.
