Abstract
A three-dimensional printing apparatus is provided, including a container, a display, a control unit and an optical film. The container contains a photosensitive material. The display has a plurality of display units. Each of the display units is capable of emitting a light beam. The control unit is capable of controlling the display units. The optical film is capable of projecting the light beams emitted from the display units onto the photosensitive material, forming a plurality of projected patterns. An arranging sequence and an arranging direction of the projected patterns are substantially the same as an arranging sequence and an arranging direction of the display units.
Claims17
A three-dimensional printing apparatus, comprising:
- a container, containing a photosensitive material;
- a display, having a plurality of display units, each of the display units being capable of emitting a light beam;
- a control unit, connected to the display and controlling the display units of the display;
- and
- an optical film, disposed between the display and the container, the optical film comprising a plurality of optical structures folined thereon and arranged in a direction perpendicular to a transmission direction of the light beams, and the optical structures respectively projecting the light beams emitted from the corresponding display units onto the photosensitive material to a plurality of projected patterns, wherein an arranging sequence and an arranging direction of the projected patterns are substantially the same as an arranging sequence and an arranging direction of the display units, and a dimension of each of the projected patterns is substantially equal to a dimension of each of the display units, so that the projected patterns are formed as not overlapping, and a distance between the display and the upper surface of the container is less than or equal to 3 cm.
A three-dimensional printing apparatus, comprising:
- a container, containing a photosensitive material;
- a display, having a plurality of display units, each of the display units being capable of emitting a light beam;
- a control unit, connected to the display and controlling the display units of the display;
- and
- an optical film, disposed between the display and the container and projecting the light beams emitted from the display units onto the photosensitive material to form a plurality of projected patterns, wherein an arranging sequence and an arranging direction of the projected patterns are substantially the same as an arranging sequence and an arranging direction of the display units, and the projected patterns are formed as not overlapping, wherein the container has a bottom, disposed between the display and the photosensitive material, the bottom is a light-transparent bottom, the bottom of the container has an upper surface facing the photosensitive material, and a distance between the display and the upper surface of the container is less than or equal to 3 cm.
