Abstract: A three-dimensional printing apparatus includes a liquid tank capable of accommodating a photosensitive liquid. The liquid tank includes a film, a plurality of side walls, a plate and a motor. The film has a workpiece curing area. The plurality of side walls surrounds the film. The plate is capable of supporting the film and having at least one fluid tunnel extending from a first surface of the plate contacting the film to a second surface of the plate. The motor is connected to the liquid tank to incline the liquid tank. A gap is formed between the plat and one of the plurality of side walls of the liquid tank, and the film is communicated with an outside space via the gap.

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 three-dimensional printing apparatus includes a liquid tank and a motor. The liquid tank includes a film and a plate. The film has a working area, and the plate supports the film and has at least one fluid tunnel extending from a first surface of the plate contacting the film to a second surface of the plate. The motor is disposed on the liquid tank, providing dragging-down traction to incline the liquid tank. The embodiments of the present invention facilitate the separation of workpieces from the film. Another three-dimensional printing apparatus and a three-dimensional printing method are also provided.

Abstract: A three-dimensional printing apparatus includes a liquid tank. The liquid tank includes a release layer and a plate. The release layer has a workpiece curing area, and the plate supports the release layer and has a first area corresponding to the workpiece curing area and a second area adjacent to the first area; the second area has at least one fluid passage extending from a first surface of the plate contacting the release layer to a second surface of the plate. The embodiments of the present invention facilitate the separation of workpieces from the release layer. Another three-dimensional printing apparatus and a three-dimensional printing method are also provided.

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.
