A kind of horizontal two-way printing three-dimensional printer

Abstract

The invention discloses a three-dimensional printer for horizontal bidirectional printing. A first suspension rod and a second suspension rod are respectively slidably installed on the sliding rods, and a second driving mechanism and a third driving mechanism can drive the first suspension rod and the second suspension rod respectively. Move horizontally and synchronously in the opposite direction on the sliding rod; the first spray head and the second spray head are respectively installed at the lower ends of the first hanger and the second hanger, and the fourth drive mechanism and the fifth drive mechanism can respectively drive the first spray head It moves up and down synchronously with the second spray head, the first spray head and the second spray head are arranged obliquely, and the starting points of the nozzles of the first spray head and the nozzles of the second spray head coincide; the control unit is used to control the first spray head and the second spray head The ejection heads respectively print half the area in the cross-section of a layer. In the present invention, two jetting heads are used to print at the same time, and each of the two jetting heads prints half of the cross-section area of ​​a layer, which shortens the printing stroke and speeds up the printing speed, thereby improving the three-dimensional printing efficiency.

Description

technical field [0001] The invention relates to the technical field of three-dimensional printers, in particular to a three-dimensional printer with horizontal bidirectional printing. Background technique [0002] 3D printer is a process of rapid prototyping. It adopts layer-by-layer accumulation to produce 3D models. Its operation process is similar to that of traditional printers, except that traditional printers print ink onto paper to form two-dimensional plane drawings. , while the 3D printer is to stack liquid photosensitive resin materials, molten plastic filaments, gypsum powder and other materials through spraying binder or extrusion to form a three-dimensional entity. According to the three-dimensional model of the product constructed by CAD, it is sliced ​​in layers to obtain the outline of the cross-section of each layer. According to these outlines, the laser beam is selectively injected to solidify layers of liquid resin or the injection source selectively inj...

Problems solved by technology

[0005] In the prior art, when printing the section of each layer, multiple lines are printed to form the section. Generally, printing starts from one end and then walks to the other end, and then turns around and prints another line, and so on. Continuously print multiple lines to complete One-layer section, so the printing stroke is longer and the printing efficiency is lower
