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
[0015] 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.
[0016] 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 2 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 by multiple print heads at the same time, that is, as image 3 as shown.
[0017] but also like image 3 As shown, the cooperative work of these three print heads will definitely make the motion tracks between the print heads cross. Since the far ends of these print heads are on the same plane, the print...

The invention provides printing heads of a 3D printer with multiple printing heads, a printing mechanism thereof and a 3D printer. The printing heads of the 3D printer comprise bases and extension heads, wherein the bases are connected with transmission mechanisms, and are controlled by the transmission mechanisms to move on movement locus planes; and the extension heads can be controlled in the vertical direction to extend outside / shrink in the bases. The printing mechanism of the 3D printer comprises at least two printing heads independent from each other; each of the printing heads is respectively connected with the transmission mechanisms, and is driven to move on the respective movement locus planes not overlapped with each other; the height of every of the printing heads after the extension head thereof shrinking in the base thereof is smaller than the gap of the printing head and the nearest another printing head under the printing head; and after the extension heads of all the printing heads extend outside the bases thereof, the bottommost ends of the extension heads are positioned on one plane.
Description
technical field [0001] The invention relates to the technical field of 3D printing, in particular to a printing head, a printing mechanism and a 3D printer of a multi-printing head 3D printer. 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 accumulation p...
