Rapid prototyping (RP) is an innovative technology, which can be used in a few hours to directly produce a complex part of the graphic design of three-dimensional CAD. The technology of laser rapid prototyping (SLA),

 rapid prototyping (LOM), rapid prototyping (SLS), rapid prototyping (FDM), 3D printing and so on. Since the first rapid prototyping system in 1988, more than twenty kinds of systems have been developed, each of which

 has some small differences. Initially, these systems are used in the automotive and aviation fields, and later in many other areas, such as toys, computers, jewelry and medicine, etc..
Three dimensional (SLA): SLA method is the earliest commercialization, market share of the highest RP technology, which is based on photosensitive resin as raw material, the computer control ultraviolet laser according to

 the parts of the different layer cross section information on the surface of the photosensitive resin surface, so that the thin layer of the resin layer of the scanning area, forming part of a thin film. After the completion of

 a layer of curing, the working table moves down a layer thickness, in order to make a new layer of liquid resin on the surface of the original cured resin, and then the next layer of the scanning process can be carried out.

 The newly solidified layer is firmly glued to the top of the front, so that it is repeated until the entire prototype is finished.

FDM (FDM): the invention of the invention in 1988. The molten material in the spray nozzle is driven by the X-Y working platform, which is based on the shape of the cross section. Commercial FDM 

equipment used in a wide range of materials, such as casting paraffin, nylon, thermoplastic, ABS, etc.. In addition to improve the efficiency of the use of multiple nozzles.

Laser selective sintering (SLS): the SLS method is used in the energy of the infrared laser, and the use of the material is more than the powder materials. When processing, the powder preheating

 to slightly lower than its melting point temperature, and then under the action of the scraping stick, the laser beam under the computer control, according to the layered cross section information

 to have a selective sintering, a layer of the next layer of sintering, after all, remove excess powder, then you can get a good sintering parts. At present, the process of the mature technology is the 

wax powder and plastic powder, the sintering process is still under study.

Laminated method (LOM): the LOM method appears in 1985. First on a substrate covered with a layer of foil material (such as paper) and with a certain power of the infrared laser under the control

 of the computer according to the hierarchical information cut out contours, while the non parts according to the grid of a certain shape into pieces in order to remove the finished a layer, and then

 covered with a layer of foil, hot roller, new shop on a layer in the role of the adhesive stick in molded body, cutting the layer shape, so repeatedly until the processing is completed. In the last part, 

we can get the whole part.
