Embodiment Construction

[0065] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments to further understand the purpose, solution and effect of the present invention, but it is not intended to limit the scope of protection of the appended claims of the present invention.

[0066] A preferred embodiment of the present invention will be described in detail below in conjunction with the drawings.

[0067] The present invention discloses a low-melting-point material printing method of a 3D printer (hereinafter referred to as the printing method for short in the description), the printing method is mainly suitable for using low-melting point materials (such as polylactic acid (PolyLactic Acid, PLA) materials) for A 3D printer is printed, which is used to solve the problem that the low-melting point material is easily deformed by heat during the printing process, and the problem of dripping when the 3D printer mo...

Abstract

The invention discloses a low-melting-point material printing method of a 3D printer. The method includes: during printing of a print layer on a printing platform, firstly controlling the movement of a 3D printer nozzle to a position on a contour inner ring and printing the contour inner ring, then controlling the movement of the nozzle to a position on a contour outer ring and printing the contour outer ring; and at the end of the contour outer ring printing, firstly controlling the movement of the nozzle to the inner side and making it depart from the scope of the contour outer ring, then changing the relative position of the nozzle to the printing platform on an Z axis so as to print a next print layer. The printing method provided by the invention firstly controls the departure of the nozzle from the scope of the contour outer ring and then makes the nozzle or the printing platform move toward the Z axis, so that dripping of the low-melting-point material cannot occur on the contour outer ring, and the appearance of a well printed 3D model cannot be affected.

Description

technical field [0001] The invention relates to a printing method of a 3D printer, in particular to a printing method of a low melting point material of the 3D printer. Background technique [0002] In recent years, the development of 3D printing technology has become more and more mature, and the price of 3D printers has become cheaper and cheaper. Therefore, 3D models made by 3D printing technology are slowly filling the lives of ordinary people. [0003] Generally speaking, most 3D printing technologies today use acrylonitrile-butadiene-styrene copolymer (Acrylonitrile-Butadiene-Styrene, ABS) resin as the printing material. However, during the printing process, ABS resin will release toxic gas and smell bad. Therefore, many new 3D printers on the market have changed to polylactic acid (Poly Lactic Acid, PLA) material. PLA is an environmentally friendly material made of corn, which can be decomposed naturally, and will not produce odor or release toxic gas during the prin...
