Embodiment 1

[0022] When printing an infinitely long object, the assembly line 14 needs to be moved forward by a distance corresponding to the height of the layer for each layer of printing. A 45° nozzle is used and the slicing direction is 45°.

Embodiment 2

[0024] When printing batch products, each gantry can be operated separately, the same object can be printed at the same time, and different objects can be printed independently. After the object is printed, the assembly line 14 moves forward. When the printed object moves to the edge due to the curvature, it can be Automatic peeling.

Embodiment 3

[0026] When multiple gantry cooperate to print the same object at the same time, the object is divided into several copies when slicing, and the number of copies is determined according to the number of gantry. At this time, the installation angle of the nozzle 3 is required to be in the vertical pipeline direction, parallel to the printing plane. Algorithmic stitching is performed on the boundaries of the segmented regions.

Abstract

The invention relates to variable printing sprayer angle printing equipment of an assembly line gantry structure based on FDM. The variable printing sprayer angle printing equipment comprises a base. The base is provided with an assembly line. One or more portal frames capable of moving back and forth in the assembly line advancing direction are erected on the assembly line. The portal frames are provided with sprayers capable of moving in the plane perpendicular to the assembly line advancing direction. The equipment has the beneficial effects that firstly, FDM printing of an object with the length in one direction far larger than the length in the other two directions is achieved; secondly, the problem about combination of the assembly line and an FDM printing method is solved, and the printed object can be automatically peeled off; thirdly, the printing slice angle can be switched, but the equipment is not limited to the changeable angle slice, and accordingly supports can be reduced; and fourthly, the situation that the multiple sprayers print the same object in a coordinated printing manner can be achieved.

Description

Technical field [0001] The invention relates to a 3D printer, in particular to a printing device with an FDM-based assembly line gantry structure and a variable printing nozzle angle. Background technique [0002] The existing 3D printer uses the XYZ three-coordinate linear guide printing mode, and the nozzle and the printing plane move in parallel. Existing printers cannot print infinitely long objects, cannot automatically peel off the entities that have been printed, cannot achieve batch printing, and cannot print the same object simultaneously with multiple nozzles. Summary of the invention [0003] The present invention aims to solve the above-mentioned shortcomings of the prior art, and provides a printing device with a variable printing nozzle angle based on an FDM-based assembly line gantry structure. [0004] The technical solution adopted by the present invention to solve its technical problems: this FDM-based assembly line gantry structure variable print nozzle angle pri...
