Problems solved by technology

However, this method itself will cause a large error. The wear of the feeding gear, the accuracy of the rubber strip itself, and the traction force of the printing head on the glue line in the moving mode will all lead to errors.
This also leads to the fact that the accuracy of the current hot melt adhesive printing method is generally not high.

Embodiment Construction

[0030] The present invention will be further described below in conjunction with specific embodiments and accompanying drawings.

[0031] See Figure 1-4 As shown, this is a 3D printer in the present invention, which includes: a print head 1, a printing platform 2, and a container 3 that provides printing materials for the print head 1, and the print head 1 can pass through in the X / Y / Z direction The upper moving mechanical arm 4 is suspended above the printing platform 2 .

[0032] The mechanical arm 4 used in the present invention is a delta robotic arm (Delta Robot), this mechanical arm generally has 3-4 degrees of freedom, can realize running on the X / Y / Z direction, and around the Z axis direction rotate. The triangular manipulator has been recorded in many patent documents as a technology that has been maturely used. See the US patent documents with patent publication numbers US 8621953 B2, US 20120103124 A1, US20120171383 A1, and 20130049261A1, all of which propose re...

Abstract

The invention discloses a printing method of a 3D product, a 3D printer used in the method, and a printer head of the 3D printer. The printing method of the 3D product comprises the following steps of: spraying material layers layer by layer through the printer head of the 3D printer; after finishing spraying of each of the material layers, performing light curing on a specified region on each of printing material layers through curing light heads arranged on the printer head; performing continuous stacking; and finally dissolving uncured regions of all material layers through a solvent to obtain a cured substance, namely the required 3D product. According to the printing method of the 3D product, which is disclosed by the invention, the flowability of gel type resins is utilized, heating set is not needed, and heating for melting does not need to be performed on raw materials; and besides, in order to overcome the flowability of the raw materials, a frame for assisting in printing operation is arranged to limit the raw materials to make sure that a height value is accurate when each material is sprayed. Compared with a conventional printing manner of a hot melt adhesive, the printing method disclosed by the invention is lower in manufacture cost and higher in precision.

Description

[0001] Technical field: [0002] The present invention relates to the technical field of a three-dimensional product manufacturing method and its equipment, in particular to a 3D product printing method, a 3D printer used in the method, and a print head in the 3D printer. [0003] Background technique: [0004] 3D printers have developed rapidly in the past few years. The existing 3D printers first need to use a computer to model before working, and then perform layered "slicing" of the built 3D model, and then "print" layer by layer from bottom to top. ” Each layer is sliced, resulting in a 3D product identical to the model built. According to this principle, the current 3D printing technology mainly includes the following two types, SLA stereolithography and hot-melt material spraying printing. The two 3D printing technologies will be introduced below. [0005] The principle of making 3D products by stereolithography is, first, design a three-dimensional solid model through...
