SLA rapid prototyping technology, also known as light curing rapid prototyping technology, is based on the principle of liquid photosensitive resin photopolymerization work. This kind of liquid material will be in a certain wavelength and intensity of ultraviolet light (such as λ = 325nm) irradiation can be rapid photopolymerization reaction, the molecular weight of the sharp increase in material colleagues from the liquid into a solid state. SLA's core technology is computer technology and materials technology. SLA laser rapid prototyping technology to abandon the traditional mechanical processing methods, according to the CAD generated parts geometric information, control of the three-dimensional CNC molding system, through the laser beam material accumulation and the formation of parts. Molded in this way, without the need for time-consuming, costly molds or special tools for the design and machining, greatly improving the production efficiency and manufacturing flexibility.
In the resin tank filled with photosensitive resin liquid, in the ultraviolet laser beam irradiation it will quickly cure. At the beginning of the molding process, the elevatable table is in the height of the next section of the liquid level, and the laser beam after focusing is scanned by the computer and scanned along the surface according to the requirements of the cross- Of the resin is cured, thereby obtaining a cross-sectional profile of the resin sheet. The table down a layer of the height of the sheet to cure the resin sheet was a layer of new liquid resin covered, so easy to carry out the second layer of laser scanning curing, the new layer of curing must be firmly bonded to the previous layer, So repeat, until the entire product molding is completed. Finally, the lifting platform lifted the surface of the liquid resin, remove the workpiece, to clean, remove the support, secondary curing and surface treatment.
