Embodiment Construction

[0026] The 3D printer proposed by the present invention will be further described in detail below with reference to the drawings and specific embodiments. According to the following description and claims, the advantages and features of the present invention will be clearer. It should be noted that the drawings are in a very simplified form and all use imprecise ratios, which are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0027] The core idea of ​​the present invention is to provide a 3D printer, which can operate simultaneously through two X-direction displacement mechanisms or two Y-direction displacement mechanisms during printing, and drive the base and the print nozzle assembly above it along the X-direction or Y-direction It can also be moved through the action of a single X-direction displacement mechanism or Y-direction displacement mechanism to drive the base and the print head assembly above it t...

Abstract

The invention provides a 3D printer. In the printing process, simultaneous movement can be achieved through two X-direction displacement mechanisms and two Y-direction displacement mechanisms, and a base and a printing spray assembly head above the base can be driven to move in the X direction or the Y direction. Through the movement of one single X-direction displacement mechanism or the single Y-direction displacement mechanism, the base and the printing spray head assembly above the base can be driven to rotate with the other X-direction displacement mechanism or the other Y-direction displacement mechanism, so that the purpose of adjusting the moving direction is achieved. Accordingly, the 3D printer can move to any position in a plane. In theory, the plane printing range of the 3D printer is limitless, in practical application, the advantage of the 3D printer on the printing range is also very obvious compared with an existing printer of the same size, the cost is lowered, and the space utilization rate is also improved.

Description

Technical field [0001] The invention relates to the field of 3D printing, in particular to a 3D printer. Background technique [0002] 3D printer is a kind of rapid prototyping technology. It is based on a digital model file, using powdered metal or plastic and other bondable materials to construct objects by printing layer by layer. The 3D printer is used to print the model, without the need for traditional cutting machine tools and molds, and the 3D entity can be directly formed according to the 3D model of the workpiece under the control of the computer. [0003] The printing nozzle is a component used to output consumables in a 3D printer. During the printing process, the printing nozzle is required to be able to move arbitrarily in the space to deal with workpieces with different external contours. Most of the print head transmission mechanisms of the existing 3D printers use the transmission mechanism of the traditional three-axis linkage machine tool, that is, the moving sh...
