  • INQUIRY

3D printing is a rapid prototyping technology, it is a digital model based on the file, the use of powdered metal or plastic and other adhesive materials, through the layers of printing to build objects in the way of technology.

3D printing is usually done using a digital technology material printer. 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, dental and medical industries, education, geographic information systems, civil engineering, firearms and other fields.

The main types are: light curing rapid prototyping STL, selective laser sintering SLS and direct metal powder laser sintering DMLS.

Stereolithography((STL)


"Stereo lithography Apparatus" abbreviation, that is, three-dimensional light curing molding method.
With a specific wavelength and intensity of the laser focused to the surface of light-cured material, so that from point to line, from line to surface sequence solidification, to complete a level of drawing operations, and then lift the vertical movement of a layer in the height, Another layer. This layer is superimposed to form a three-dimensional entity.

Selective laser sintering (SLS)


Selective laser sintering is the SLS method using infrared lasers for energy, the use of modeling materials are mostly powder material. In the process of processing, the powder is preheated to a temperature slightly below its melting point and then the powder is paved by the action of a flattened stick. The laser beam is selectively sintered under the control of the layered section according to the layered section information. And then the next layer of sintering, all sintering finished after removing the excess powder, you can get a sintered parts. At present the mature process materials for the wax powder and plastic powder.More>>


Direct metal laser sintering( DMLS)


Laser sintering laser sintering, with laser as the heat source of the powder compacting sintering technology. This technology has unique advantages to sintering materials that are not readily available for conventional sintering furnaces. As the laser beam concentration and penetration capacity is small, suitable for small area, thin product sintering. It is easy to sinter the powder or sheet compact different from the matrix component together. The use of laser can achieve high melting point metal and ceramic bonding. Compared with other rapid prototyping technology, laser sintering prepared parts, with good performance, production speed, material diversification, low cost. Europe and the United States and Japan have gradually recognized laser sintering for the next generation of rapid manufacturing technology standards.More>>
