Problems solved by technology

[0005] In view of this, it is necessary to provide a lamination method of 3D printing materials to solve the deformation of the material during the lamination process. In the process of layer-by-layer printing, there is insufficient pressure applied to the upper layer of material, and the lamination between material layers loose issue

Embodiment

[0056] Embodiment: A method of changing the pressing force by changing the distance between the pressure roller and the print head.

[0057] The height of a single layer of printing material is 0.6mm, that is, the initial distance between the printing nozzle and the printing plate is 0.6mm, the distance between the pressing point and the printing plate is 0.3mm, and the distance between the pressure roller and the printing nozzle is also 0.3mm. Assuming that the diameter of the material is 0.6mm, the layer height of the first printing without pressure is 0.6mm, and under the pressure of the pressure roller, the layer height of the first layer becomes 0.3mm after printing. After the first layer is printed, both the print nozzle and the pressure roller will rise to a layer height of 0.6mm, which will cause the print nozzle to rise to 1.2mm, and the pressure roller to rise to 0.9mm. At this time, the first cured layer will have been printed As a printing plate for printing on the...

Abstract

The invention relates to a pressing method for 3D printing materials. The pressing method comprises the steps that information of the printing materials is input; the current printing layer number is acquired; the pressing force is adjusted according to the current printing layer number and the information of the printing materials; materials of the current printing layer number are printed, and the current layer is pressed through the adjusted pressing force. The problems that the materials are deformed in the pressing process, pressure applied to the upper-layer material is insufficient in the layer-following printing process, and pressing between the material layers is not tight are solved.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a pressing method of 3D printing materials. Background technique [0002] 3D printing is a kind of rapid prototyping technology, also known as additive manufacturing. It is a technology based on digital model files and using bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing. , ordinary printers used in daily life can print flat objects designed by computers, and the so-called 3D printers are basically the same as ordinary printers, but the printing materials are somewhat different. The printing materials of ordinary printers are ink and paper, while 3D printers are equipped with Different "printing materials" such as metal, ceramics, plastic, sand, etc. are real raw materials. After the printer is connected to the computer, the "printing materials" can be superimposed layer by layer through computer control, and finally the b...
