Principle of 3D Printing
UV curing additive manufacturing resin curing materials cure by UV high resolution projector layer by layer UV curing additive manufacturing resin to create a 3D printed piece. Molding process: The LCD/DLP printers contain a liquid tank that can hold the resin and resin storage, the LCD/DLP imaging system is placed below the tank and its imaging surface is located at the bottom of the tank. By energy and graphic control, a thin layer of resin (50μm/25μm) of a certain thickness and shape can be cured each time (this layer of resin is exactly the same as the section obtained from the previous section). A lifting mechanism is set above the liquid tank. After each section exposure, it is lifted to a certain height (the height is consistent with the thickness of the layer). The current cured solid resin is separated from the bottom of the liquid tank and bonded to the pull-plate or the resin layer formed last time. In this way, through layer by layer exposure and lifting to generate three-dimensional entities, the final result is the washed resin cured piece after curing.
