UV curing process, also known as stereo lithography, is a relatively early developed rapid prototyping technology. It uses photosensitive resin as raw material and is solidified by computer controlled ultraviolet laser. This method can easily and automatically produce complex three-dimensional shapes that have been difficult to produce by various processing methods. Next, let's talk about the forming process and characteristics of Shandong Rapid Prototyping UV curing technology.
Molding process of UV curing molding process:
The liquid tank is filled with liquid photosensitive resin. Under the control of the control system, the ultraviolet laser beam from the helium-cadmium laser or argon ion laser scans the surface of the photosensitive resin point by point according to the information of each layer section of the part, so that the thin layer of the resin in the scanned area can be solidified by photopolymerization reaction, forming a thin layer of the part.
After the first layer is cured, the workbench moves down a layer of thickness to make a new layer of liquid resin on the surface of the previously cured resin. The scraper scrapes the liquid level of the resin with high viscosity, and then carries out the scanning processing of the next layer. The newly cured layer is firmly bonded to the previous layer. Repeat until the whole part is manufactured, and a three-dimensional solid prototype is obtained.
The molding process is highly automated. The SLA system is very stable. After processing, the forming process can be completely automated until the prototype is completed.
High dimensional accuracy. The dimensional accuracy of SLA prototype can reach ± 0.1mm.
Excellent surface quality. Although steps may appear on the side and surface of each layer during curing, the upper surface can still get a glass-like effect.
You can make models with very complex structures.
It can directly produce the lost foam with hollow structure for investment casting.
