Abstract: On embodiment of the invention provides an optical lens includes a lens barrel, a first lens group and a photo interrupter disposed in the lens barrel, a light-shading sheet and a power machine. The photo interrupter has an optical transmitter and an optical receiver, the optical transmitter emits a light beam in a first direction, and the optical receiver receives the light beam. The light-shading sheet is disposed in a propagation path of the light beam and has two shading parts with mutually different lengths. The power machine is linked to a kinetic machine part, and the kinetic machine part is connected to the first lens group.

Abstract: A three-dimensional printing apparatus includes a liquid tank, a curing platform and a light source device. A bearing member of the liquid tank is air proof, and forms an accommodating space with a side wall of the liquid tank. The curing platform is disposed at a first side of the bearing member corresponding to the accommodating space for allowing a workpiece to be cured on a surface thereof. After the accommodating space accommodates a liquid material, a curing light beam provided by a light source device disposed at a second side of the bearing member opposite to the accommodating space cures at least part of the liquid material on a surface of the curing platform via the bearing member. The use of a solid release material between the curing platform and the bearing member may be omitted. Methods for printing and releasing a three-dimensional workpiece are also provided.

Abstract: A projection device is disposable into a display platform of a display rack having a plurality of display platforms, for directly projecting an image frame onto a projection screen of the display platform. The image frame projected to the projection screen is not reflected by any reflective mirror arranged between the projection device and the projection screen. A length of the image frame in a first direction is equal to at least ten times a length of the image frame in a second direction. Since no reflective mirror is arranged between the projection device and the projection screen, the projection device is more easily applicable to display racks.

Abstract: One embodiment of the invention provides a three-dimensional printing system includes a first projector, a second projector, and a solidification region. The solidification region accommodates a curable material and has a first area and a second area. The first projector projects a first image on the first area, the second projector projects a second image on the second area, and the first image and the second image are stitched together to form an image seam. The image seam is the only one overlapping area between the first image and the second image, and a width of the image seam is smaller than a span of five consecutive pixels arranged crossing the image seam.
