Abstract

The invention discloses an inversion type restricted ultraviolet light 3D (three-dimensional) printer, which comprises a machine frame, wherein the machine frame comprises an upper base and a lower base; a plurality of support posts are arranged between the upper base and the lower base; an upright post is arranged at one side of the upper base; the upright post is vertical to the upper base; a curing work table is fixed at the side surface of the upright post through an ascending and descending mechanism; the ascending and descending mechanism is connected with a control system; a resin groove is formed in the upper base arranged under the curing work table; the curing work table is parallel to the resin groove; a laser system is arranged on the lower base arranged under the resin groove. The structure is reasonable; the stability and the accuracy of equipment are greatly improved; the printing performance is good; the printing formed layer thickness is uniform; the fault rate is low.

Description

technical field [0001] The invention relates to a three-dimensional printer, in particular to an inverted constrained ultraviolet three-dimensional printer. Background technique [0002] 3D printer, also known as three-dimensional printer (3DP), is a kind of additive manufacturing technology, that is, a machine of rapid prototyping technology. It is based on a digital model file and uses printing materials such as photosensitive resin, powdered metal or plastic. Three-dimensional objects are created by printing layers of adhesive materials. With the diversified development of 3D printing materials and the innovation of printing technology, 3D printing not only shows extraordinary development potential in the traditional manufacturing industry, but also extends its potential to medical care, food manufacturing, luxury clothing, film and television media, and education. Many fields are closely related to people's life. [0003] 3D printing technology alleviates the forming p...
