Problems solved by technology

In addition, in order to ensure that the print head has sufficient formation during the movement process, sufficient length must be reserved for the power line and signal line. However, the reserved length is prone to interfere with the printed three-dimensional entity during printing. Especially for large-scale 3D printers, when the 3D printer is printing, the power lines and signal lines connected to the print head are likely to touch or interfere with other components on the print head or the 3D entities being printed, affecting the 3D printing. The printing of solids will cause "destruction" to the printed 3D solids, or lead to unsuccessful printing

Abstract

The invention provides a three-dimensional printer and a printing method thereof. The three-dimensional printer comprises a frame; the frame comprises an upper support base and a lower support base oppositely arranged, and three sets of driving devices; and the three sets of driving devices are uniformly arranged between the upper support base and the lower support base in the peripheral direction of the upper support base. The three-dimensional printer further comprises a printing platform and a first printing head; the first printing head is fixedly mounted on the upper support base; each set of driving devices comprises a guide rail, a connecting block, a support arm and a driving module; the guide rail is connected between the upper support base and the lower support base; the connecting block is slidingly connected with the guide rail in the extension direction of the guide rail; two ends of the support arm are respectively hinged with the printing platform and the connecting block; and the driving module drives the connecting block to move back and forth along the guide rail. The invention further discloses a printing method of the three-dimensional printer. The three-dimensional printer and the printing method thereof can prevent touch and interference with a power supply wire and a signal wire connected with the printing head and a printed three-dimensional solid during printing.

Description

technical field [0001] The present invention relates to the technical field of printing, in particular to a three-dimensional printer and a printing method of the three-dimensional printer. Background technique [0002] A three-dimensional printer is a device that uses rapid prototyping technology to print three-dimensional objects. It is based on a digital model and uses materials such as plastic or powdered metal to print three-dimensional objects layer by layer. The process of 3D printing is firstly modeled by computer-aided design (CAD) or computer animation modeling software, and then the built 3D model is "divided" into layer-by-layer sections, and then the processing path is obtained according to the analysis section information, so as to guide the printer step by step. layer printing. According to different working principles, the rapid prototyping technologies used include melt extrusion molding, laser selective sintering molding, and photocuring molding. [0003]...
