- the light source 3 includes a LED light array 31 and a reflector 32 disposed around the LED light array 31 . Since the optically-transmissive wall 111 of the tank body 1 and the LCD display unit 14 in the present application have a large size or an ultra large size of 20 ⁇ 120 inches, the area of the LED light array 31 should match this size. That is, when the optically-transmissive wall 111 reaches the maximum size of 120 inches, in general, the size of the LED light array 31 is no larger than 120 inches; in other words, the size of the LED light array is smaller than or equal to the size of the optically-transmissive wall 111 .

- the control unit 4 again turns the light source 3 on to irradiate the liquid photosensitive resin in the tank body 11 , to allow a post-cured thin layer to be accumulatively superposed on the previous thin layer.
- a completed printed object is formed by repeating the above procedure.
- the printed object is finally formed transversely on the load-bearing element 13 and is always immersed in the liquid photosensitive resin in the tank body 11 .
- the buoyancy provided by the liquid photosensitive resin can substantially offset the weight of the printed object, so that the printed object is not apt to fall off the load-bearing element 13 , and will not apply an excessive shearing force on the load-bearing element 13 , thus avoiding the problem in the conventional art that the printing platform produces an offset in the vertical direction because the printed object is oversized. Therefore, compared with the conventional art, the size of the cross section of the printed object may obviously increase to 20 ⁇ 120 inches.
- the present application can be used to print an object with a larger cross-sectional size, such as 20 ⁇ 120 inches, apparently it also can print an object with a size equal to or smaller than 20 inches, like the conventional object of 14 inches.
- the present application is not intended to limit the definition of the size of the resin tank, and referring to the above description, the size of the optically-transmissive wall of the resin tank 1 may actually select any size below 120 inches, including a size of 20 ⁇ 120 inches and a size equal to or smaller than 20 inches.
- the buoyancy provided by the liquid photosensitive resin can substantially offset the weight of the printed object, the resin tank of the present application can adopt a longer dimension in the direction in which the transverse guide element extends, thereby enabling the 3D printer of the present application to print higher (or longer) objects.
