Abstract

The invention discloses a 3D (three dimensional) printing method and a 3D printer. The method includes the steps of: making use of 3D modeling software in a computer to conduct modeling for an object needing printing; controlling the rise of a lifting platform by the computer; controlling a constant upper surface height of the liquid UV light cured resin in a liquid storage tank by the computer; carrying out printing from a first layer to the shell of a last layer in order, and in the shell printing process, letting the computer control descending of the lifting platform by one layer height in order through a Z-axle motor, making the liquid UV light cured resin in the liquid storage tank flow into the shell, and filling the shell; at the end of shell printing, controlling a wire extrusion device and making it stop extruding pasty UV light cured resin by the computer, and controlling an ultraviolet lamp in terms of irradiating the shell for a period of time by the computer so as to make the liquid UV light cured resin in the shell cured. With high printing efficiency, the 3D printing method and the 3D printer provided in the invention can ensure that the printed object has high density and is easy to damage while guaranteeing the printing efficiency.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a 3D printing method and a 3D printer with high printing efficiency. Background technique [0002] The working principle of 3D printers is basically the same as that of ordinary printers. It is to superimpose "printing materials" layer by layer through computer control, and finally turn the blueprint on the computer into a real object. This is a technological revolution that subverts traditional manufacturing processes. [0003] Common 3D printers print very slowly and are expensive. If you want to improve the printing efficiency of common 3D printers, you need to reduce the filling rate of the filling rate parameter, and the reduction of the filling rate will lead to a decrease in the density and strength of the printed object. Difference. [0004] Therefore, common 3D printers can only be used in places such as scientific research institutions, and 3D printing technology c...
