Embodiment Construction

[0033] figure 1 It is a structural diagram of the main hardware of the device of the present invention. The computer 1 is equipped with layered data processing software, the main function is to send the cross-sectional graphics to the digital projector, and control the graphics projection mode of the projector; the digital projector 2 receives the image data from the computer, and according to the set exposure mode , the graphic projection is irradiated onto the resin surface; the ultraviolet lamp 4 arranged in the ellipsoid reflector 5, the light emitted by the ultraviolet lamp 4 is reflected by the ellipsoid reflector 5, and forms parallel ultraviolet light through the lens 3 and enters the digital projector 2; The molding system includes a resin tank 6, on which a screen 7 driven by a lifting device 8 is arranged, and above the screen 7 there is a scraping device 9, which is used to remove the liquid resin layer on the screen 7 Or the surface of the molded workpiece forms ...

Abstract

The invention discloses a digital projection photofixation quick molding device which includes the computer, the digital projecting apparatus, the lens, the ultraviolet light, the ellipsoidal reflector, the resin canal, the screen, the lifting motion and the striking device. It projects the figure of the CAD section on the surface of the liquid photosensitive resin by the digital projecting apparatus. When the forming layer reaches a solidified degree, the forming platform falls down to the height of a layer thickness, and the surface of the forming layer is covered with the liquid photosensitive resin, then to solidify the next layer. The invention has the high precision and simple process, so it can be used for the quick forming field.

Description

technical field [0001] The invention belongs to the advanced manufacturing technology field of the manufacturing industry, and relates to a novel digital projection photocuring rapid prototyping method and device. Background technique [0002] Rapid prototyping technology is an advanced manufacturing technology developed in the 1980s. Rapid prototyping manufacturing technology is the result of integrating modern numerical control technology, CAD / CAM technology, laser technology and new material science. It quickly turns abstract CAD design data into real objects without molds and tooling.
