Problems solved by technology

making the overall physical structure less stable
During the printing process, the back and forth movement of the print head, the cooling fan of the print head, and the operation of the feeder all bring vibrations.
Insufficient structure will affect printing accuracy comprehensively

Embodiment Construction

[0017] Such as figure 1 shown. The 3D printer uses a ball screw type serial structure rapid prototyping structure, and the Z-axis screw in the 3D printer uses a ball screw. It includes an X-axis mounting table, a Y-axis mounting table, and a Z-axis mounting table. The X-axis mounting table is provided with an X-axis optical rod 1 and an X-axis stepping motor 2. A 3D printing head 3 is slidably installed on the X-axis optical rod 1, and The X-axis stepping motor 2 drives the 3D printing head 3 to slide on the X-axis optical rod 1, the Y-axis mounting table is provided with the Y-axis optical rod 4 and the Y-axis stepping motor 5, and the X-axis mounting table is slidably installed on the Y-axis optical rod 4 , and the Y-axis stepping motor 5 drives the X-axis mounting table to slide on the Y-axis polished rod 4, and the Z-axis mounting table is provided with a Z-axis polished rod 6, a Z-axis ball screw 7, and a Z-axis stepping motor 8, and the Y-axis is installed The platform...

Abstract

The invention discloses a ball screw type serial structure rapid molding structure for a 3D printer. In the 3D printer, a Z-shaft screw adopts a ball screw. The ball screw type serial structure rapid molding structure provided in the invention can reduce the error of a printing head during micro-stepping, eliminate hysterisis error as far as possible, and simultaneously increases the stability of the whole structure.

Description

technical field [0001] The invention relates to the field of transmission structure of a printing head of a 3D printer, in particular to a rapid prototyping structure of a ball screw type serial structure for a 3D printer. Background technique [0002] 3D printers are a new type of rapid prototyping machine that has existed for a long time but has only recently entered the consumer market. The parts designed by people on the computer can be quickly "manufactured" without mold casting or milling. [0003] Consumer-grade 3D printers are limited by cost considerations, and have made great compromises in printing accuracy and printing speed. [0004] The printing accuracy is mainly determined by two aspects, the positioning accuracy (stepping) accuracy of the printing head and the extrusion accuracy of the printing head. [0005] The step accuracy of the print head, because it is a set of three-axis movable mechanical structure, has a greater weight than the print head. [00...
