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 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 device includes a plane, a projector, a separation mechanism, and a driving mechanism. The plane is used to put a first photocured material and a second photocured material. The projector emits a light to cure the first photocured material and the second photocured material. The separation mechanism is disposed on the plane and used for separating the first photocured material and the second photocured material, and the driving mechanism drives the separation mechanism to change a location of the first photocured material on the plane.

Abstract: A three dimensional printing mechanism includes a plane receiving a first photocured material and a second photocured material which is different from the first photocured material. A first photocured material supplying mechanism is used for inputting the first photocured material into the plane, whereas a second photocured material supplying mechanism is used for inputting the second photocured material into the plane.

Abstract: A three dimensional printing device includes a plane putting a photocured material. A pusher mechanism has a contact end above the plane, wherein the contact end is used to contact and remove a portion of the photocured material. The remnant thickness of the removed photocured material is larger than the thickness of a layer of cured pattern.
