The tank is filled with liquid photosensitive 3d printed resin, and the 3d sla resin solidifies quickly when exposed to a uv laser beam emitted by the laser .
At the beginning of molding, the lifting table is below the liquid level, just a height of the cross-section layer thickness.
Through the laser beam focused by the lens, the section profile is scanned along the liquid level according to the machine instructions.
The table drops the height of one layer of section layer thickness and solidifies the other layer of section.
After a Long development time, mature process, widely used. Uv curing molding systems account for about 60% of the rapid forming machines installed worldwide.
The molding speed is fast and the system works stably.
High precision, can be done micron level, such as 0.025mm.
Good surface quality, relatively smooth,suitable for fine parts.
