3D printer

Abstract

The invention discloses a 3D printer. The 3D printer comprises a printing device, a base plate and an industrial control PLC, wherein the two sides of the base plate are provided with a gantry type bracket for mounting the printing device; the lower parts of supporting columns at the two sides of the gantry type bracket are hinged with the base plate which is provided with an object carrying platform for installing printed objects; a cross beam of the gantry type bracket is provided with a line supplying drum for supplying raw printing lines to the printer and a bearing plate; the two sides of the cross beam are vertically provided with two bearing plates for supporting the drum; and the lower parts of the two bearing plates are respectively hinged with the cross beam. The 3D printer disclosed by the invention has the advantages of easiness in folding, convenience in installation, storage and use, simple structure and easiness in implementation.

Description

technical field

[0001] The invention relates to a printer, especially a 3D printer. Background technique

[0002] Most of the existing 3D printers are bulky, and their installation and use take up a lot of space, which is inconvenient. Although some 3D printers use a folding structure, the folding structure used in them makes the structure of the printer tends to be complicated, which brings inconvenience to maintenance and maintenance. , Too many moving parts can also easily reduce the accuracy of 3D printing.

[0003] Publication No. 203876228U discloses a folding structure of a 3D printer. The folding part includes movable parts such as a box cover and a slider. When folding, it needs to be divided into multiple steps, and when folding, the X and Z axes must pass through the slider. Folding can only be realized by sliding on the Y-axis, which increases the number of moving parts, and it is easy to increase the mutual wear between the moving parts during frequent folding,...
