Problems solved by technology

Since the two print heads are fixed together, their X-axis and Y-axis coordinates are almost identical, and only one print head is working at any time, so its improvement in printing efficiency is extremely limited

Embodiment Construction

[0024] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the accompanying drawings and specific examples.

[0025] The motion locus of the print head of the 3D printer in the prior art is a plane, so if you want to set up multiple independent print heads, you must make the motion locus planes of these print heads non-overlapping, for example, figure 1 Shown is a 3D printer with 3 print heads. And the far ends of these print heads must be on a plane, so that a print surface of the workpiece (that is, a cross section of the workpiece) can be printed simultaneously by multiple print heads. The principle of the 3D printer using two print heads is the same, and there will also be a problem of conflict between the print heads during the work process.

[0026] Therefore, the embodiment of the present invention divides the printing area into several conflic...

Abstract

The invention provides a printing area control method and printing method of a double-printing-head 3D printer. The printing area control method comprises the steps that the shape of a section of a workpiece is obtained, and at least one middle conflict area and non-conflict sub areas outside the middle conflict areas are determined from the section. According to the printing area control method and printing method of the double-printing-head 3D printer in the technical scheme, the phenomenon that in the printing process, printing heads conflict with each other can be avoided, the two printing heads can be adopted to perform printing at the same time, and therefore the printing efficiency is improved. Preferably, the round middle conflict areas can be adopted, the calculation method of the circle center and the radius is provided, and therefore the conflict areas can be minimized, and the non-conflict areas are maximized. When the non-conflict areas are maximized, a printed area can be maximized, and therefore the printing efficiency can be maximized.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a method for controlling the printing area of ​​a multi-print head 3D printer and a printing method. Background technique [0002] 3D printing is a new type of molding technology, among which filler accumulation printing technology is the most commonly used 3D printing technology. The structure of the 3D printer in the prior art is generally divided into upper and lower layers, the upper layer is the printing head and the XY transmission structure, and the lower layer is the loading platform. The XY transmission structure of the upper layer includes a printing head capable of moving on the plane formed by the X axis and the Y axis, and the lower layer is provided with a loading platform. The loading platform of the 3D printer in the prior art can rise or fall along the Z-axis direction, so as to print the 3D workpiece layer by layer. [0003] When printing, the filler accum...
