[0039] The method for forming a three-dimensional object includes the following steps. First, a feeding step is performed to add a photosensitive resin into a photosensitive resin tank. The photosensitive resin may be an existing photosensitive resin used for forming a three-dimensional object. The photosensitive resin can be a liquid, preferably, the liquid has a certain viscosity. The adding method of photosensitive resin can be added at one time or adopt automatic adding system to realize the continuous replenishment of the photosensitive resin in the photosensitive resin tank. In such an embodiment, the notch of the photosensitive resin tank may be closed.

[0040] Next, the planar laser generation step is performed, the laser emits a planar laser beam, and the planar laser beam enters the inside of the photosensitive resin tank. At the same time, the focusing lens moves relative to the laser to adjust the focus position of the laser beam. The intensity of the planar lase...

Abstract

The invention relates to a photocuring three-dimensional printer and a three-dimensional object molding method. The photocuring three-dimensional printer comprises a photosensitive resin groove; plane laser units are respectively arranged in at least two side surface directions of the photosensitive resin groove; the photosensitive resin groove has a transparent part; the plane laser units have lasers and focusing lenses; the lasers can generate plane laser beams; the focusing lenses are arranged on optical paths of the lasers; and focusing positions of the plane laser beams in the photosensitive resin groove are adjustable. The photocuring three-dimensional printer realizes the layer-by-layer curing of photosensitive resins, so that the molding efficiency is improved; and the control process of the plane laser beams is simpler and easy to operate.

Description

technical field [0001] The invention relates to the field of rapid prototyping, in particular to a photocuring three-dimensional printer and a three-dimensional object forming method. Background technique [0002] At present, three-dimensional (3D) printing uses a variety of materials according to different forming principles. These materials include materials such as photosensitive resin, acrylonitrile-butadiene-styrene plastic (ABS), wax type, and metal materials such as stainless steel, cobalt-chromium-molybdenum alloy, and aluminum alloy. However, the existing printing methods generally can only print line by line and layer by line, and cannot realize rapid forming of one layer or multi-layer printing at one time, so there is a problem of slow printing speed. [0003] The laser has the advantages of short wavelength, high resolution, concentrated energy, and stability. The energy density of the laser at a certain position is related to the size of the laser spot. The sm...
