Problems solved by technology

This molding method has the characteristics of fast molding in theory, but in fact it is very difficult to realize. On the one hand, this 3D stereoscopic projection technology is still in the experimental stage and the technology is not mature. It controls the laser in three-dimensional space. The strength is not easy to achieve, which has a negative impact on the accuracy of the molding process
Moreover, for three-dimensional objects with voids and cavities inside, the effect of this three-dimensional molding method is not ideal, especially the molding around the surface of the cavity, sometimes it cannot be realized

[0045] 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.

[0046] 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 photo-cured three-dimensional printer and a forming method of a three-dimensional object. The photo-cured three-dimensional printer comprises a photosensitive resin tank; plane laser units are arranged on the outer sides of at least two side surfaces of the photosensitive resin tank; at least a part of each side wall, corresponding to one plane laser unit, of the photosensitive resin tank is a transparent part; each plane laser unit is provided with a laser and a focusing lens; the lasers generate plane type laser beams; the focusing lenses are arranged in light paths of the corresponding lasers; and focusing positions of plane type laser beams in the photosensitive resin tanks can be adjusted. The forming method of the three-dimensional object adopts the photo-cured three-dimensional printer to print and realizes the effect of photocuring. The photo-cured three-dimensional printer realizes the effect of layer-by-layer curing of photosensitive resin, the forming efficiency is improved, a control process of the plane type laser beams is simple, and the operation is easy.

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] The existing three-dimensional (3D) printing technology uses a variety of materials according to different forming principles. These materials include photosensitive resin, acrylonitrile-butadiene-styrene plastic (ABS), wax type and other materials. It also includes 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] For example, if the printed object is figure 1 As shown in the object 80, the object 80 includes a plurality of vertically extending boards 81, 82, and also includes a horizonta...
